Description

Field of the invention The present invention relates to components for use in construction of structures, in particular a frame assembly for a window or door, and a modular roofing panel, and kits of parts related thereto. Background to the invention It is known to form temporary structures (typically buildings) from modular building blocks, such as those in WO 2004 / 052667. An opening can be defined in a wall of a structure formed from modular building blocks, such as to provide a window opening. When forming a temporary structure, there is often a need to provide a weatherproof shell, as well as internal walls with openings therein, such as for windows and closable doors. Typically, a temporary structure should be quick to assemble (and optionally disassemble). It is in this context that the present inventions have been devised. Summary of the invention In accordance with an aspect of the present invention, there is provided a kit of parts to form a frame assembly for framing an opening defined in a wall of a structure, the wall formed from modular building blocks. The kit of parts comprises: a first frame having a first frame inner portion to extend at least partially into the opening and a first frame outer portion. The first frame outer portion is to extend away from the opening, over a first surface of the wall. The kit of parts further comprises a second frame having a second frame inner portion and a second frame outer portion. The second frame outer portion is to extend away from the opening, over a second surface of the wall. The second surface is facing away from the first surface of the wall. The first frame is configured to be secured to the second frame via the first frame inner portion and the second frame inner portion to form the frame assembly and retain the frame assembly within the opening in the wall. Thus, a frame assembly can be provided to allow further components to be mounted within the opening defined in the wall of the structure. The frame assembly can be installed in a simple manner, during or after assembly of the wall from the modular building blocks. By securing the first frame to the second frame via the first frame inner portion and the second frame inner portion, and by having a first frame outer portion extending over a first surface of the wall, and a second frame outer portion extending over a second surface of the wall, the frame assembly is securely retained within the opening in the wall. The portion of the wall forming the boundary of the opening is sandwiched between the first frame outer portion and the second frame outer portion. Advantageously, this avoids a requirement for different types of modular building blocks to be manufactured - i.e., it is not necessary to separately fabricate modular building blocks with and without built-in frame functionality. The wall defines a wall plane in the plane of the wall, and a through-wall direction perpendicular to the wall plane. Typically, the first frame inner portion is arranged to extend in a direction having at least a component parallel to the wall plane. The first frame inner portion may be arranged to be provided recessed within the opening from the first surface of the wall. The first frame inner portion may extend directly from a first frame intermediate portion of the first frame, the first frame intermediate portion provided between the first frame outer portion and the first frame inner portion. The first frame intermediate portion may extend in a direction having a component perpendicular to a plane of at least one of the first frame inner portion and the first frame outer portion. The first frame inner portion may extend in a direction parallel to the first frame outer portion. The second frame inner portion may extend at least partially into the opening. The second frame inner portion may be arranged to extend in a direction having at least a component parallel to the wall plane. The second frame inner portion may be arranged to be provided recessed within the opening from the second surface of the wall. The second frame inner portion may extend directly from a second frame intermediate portion of the second frame, the second frame intermediate portion provided between the second frame outer portion and the second frame inner portion. The second frame intermediate portion may extend in a direction having a component perpendicular to a plane of at least one of the second frame inner portion and the second frame outer portion. The second frame inner portion may extend in a direction parallel to the second frame outer portion. It may be that the first frame and the second frame have the same shape. In other words, it may be that the first frame is substantially identical to the second frame. Thus, economies of scale and manufacturing simplicity can be realised because it is possible to manufacture both the first frame and the second frame by manufacturing two first frames. It may be that the first frame is formed from two or more first frame components, such as an upper first frame component and a lower first frame component. Each first frame component (e.g. the upper first frame component and the lower first frame component) can be assembled to form the first frame. Similarly, it may be that the second frame is formed from two or more second frame components, such as an upper second frame component and a lower second frame component. Each second frame component (e.g. the upper second frame component and the lower second frame component) can be assembled to form the second frame. Thus, even for relatively large openings, the frames can be formed from components smaller than the total size of the opening, thereby making it easier to transport components to form the frame assembly. The structure may be a building. The building may have a floor. The building may have a roof. The building may have foundations. The building may comprise a plurality of walls. The building may be a temporary shelter. It may be that the building can be disassembled for re-assembly at a different time and / or in a different location. It will be understood that the frame assembly may extend around one or more sides of the opening, such as around at least three sides of a four-sided opening, for example around each side of the opening. It may be that a further component is mounted to the first frame inner portion and the second frame inner portion. Thus, the frame assembly can be used to mount the further component within the opening. It may be that the further component is sandwiched between the first frame inner portion and the second frame inner portion. The further component may be configured to allow the opening to be selectively opened or closed. It will be understood that in some examples the opening can be considered closed when access therethrough that would be possible when the opening is open, is not possible, even if the closure of the opening is not air-tight. It may be that the further component comprises a pivot connection, such as a hinge. The frame assembly may be a window frame assembly. The frame assembly may be a door frame assembly. Thus, similar concepts can be used to provide both a door frame assembly and a window frame assembly within a building formed from modular building blocks. The further component may be at least partially translucent or transparent. In other words, the further component may comprise or be a windowpane, such as when the frame assembly is a window frame assembly. The further component may comprise one or more vents to allow airflow therethrough. The further component may be substantially any component desired to be installed within the opening in the wall, such as an air conditioning unit. The further component may comprise or may be for connection to an access member configured to selectively permit or restrict access therethrough. The further component may be a hinge portion. The frame assembly may be for connection to the access member via the hinge portion. The access member may be a door. The access member may be a gate. It may be that the access member is formed in one or more parts, such as at least two parts, for example an upper door member and a lower door member. It will be understood that other types of access member are possible, such as a roller blind, a roller door, and strip curtains. The first surface of the wall may be an external surface of the structure. The second surface of the wall may be an internal surface of the structure. Thus, the frame assembly may be for framing an opening in an external wall of the structure. In some examples, it may be that both the first surface and the second surface of the wall are internal surfaces of the structure, and therefore the frame assembly may be for framing an opening in an internal wall of the structure. The first frame outer portion may comprise an edge region angled towards the first surface of the wall. Thus, the edge region reduces the potential for ingress of unwanted matter between the first surface of the wall and the first frame outer portion, which may be particularly relevant when the first surface of the wall is an external surface of the structure (or when the first surface of the wall is a surface of the structure likely to be exposed to matter which should not be permitted to enter through the opening via any opening between the first frame outer portion and the first surface of the wall). By being angled towards the first surface of the wall, this ensures that the edge region is closer to the first surface of the wall than at least one other region of the first frame outer portion. Alternatively or additionally, it may be that the edge region of the first frame outer portion is arranged to contact the first surface of the wall when the frame assembly is installed. The kit of parts may further comprise at least one sealing member. A first frame sealing member may be configured to be provided between a boundary region of the opening defined in the wall and the first frame. A second frame sealing member may be configured to be provided between the boundary region of the opening defined in the wall and the second frame. Thus, the kit of parts may include sealing member(s) to restrict ingress of unwanted matter (e.g. water) around the edge of the frame assembly. It may be that the first frame sealing member is configured to be provided between the first surface of the wall and the first frame, such as the first frame outer portion. It may be that the second frame sealing member is configured to be provided between the second surface of the wall and the second frame, such as the second frame outer portion. Any of the sealing members may be formed as a loop. In some examples, it may be that a sealant paste is configured to be provided to form the sealing member once set during installation. The kit of parts may further comprise one or more inner frame fasteners to secure the first frame to the second frame. Specifically, the inner frame fasteners may be to secure the first frame to the second frame via the first frame inner portion and the second frame inner portion. It may be that at least one of (e.g. each of) the first frame inner portion and the second frame inner portion have defined therein one or more openings to receive the inner frame fasteners. In other examples, it may be that the one or more inner frame fasteners are pre-mounted to (e.g. integrally formed with) at least one of the first frame inner portion and the second frame inner portion. At least one of the first frame and the second frame may be configured to be secured to the wall using outer frame fasteners. It may be that the kit of parts comprises one or more outer frame fasteners. It may be that at least one of (e.g. each of) the first frame outer portion and the second frame outer portion have defined therein one or more openings to receive the outer frame fasteners. It may be that the outer frame fasteners are arranged to be inserted into an end member of the wall, secured to a lower side of a row of modular building blocks forming an upper side of the opening around which the frame assembly is to be provided. It may be that the one or more openings defined in the at least one of the first frame outer portion and the second frame outer portion may be defined in fewer than all sides of the outer portion(s), such as in only a top side of the outer portion(s). The present invention extends to a first frame for use in the kit of parts described hereinbefore. In particular, the first frame comprises a first frame inner portion to extend at least partially into an opening and a first frame outer portion, the first frame outer portion to extend away from the opening, over a first surface of the wall. The first frame may include any one or more of the features described in relation to the first frame in the kit of parts, as described hereinbefore. The present invention extends to a frame assembly formed from the kit of parts described hereinbefore. In accordance with another aspect of the present inventions, there is provided a modular roofing panel, configured to cooperate with one or more further modular roofing panels having substantially the same shape as the modular roofing panel, to form a roof (e.g. a pitched roof). The modular roofing panel has one or more openings defined therein. The one or more openings may be defined in a first region of the modular roofing panel. The first region of the modular roofing panel is to provide an outer surface of the pitched roof. The or each opening is configured to be covered by a cover member to secure the modular roofing panel to a roof support structure on which the modular roofing panel is to be mounted. Thus, a roof can be formed using a modular roofing system where the modular roofing panels cooperate to form the roof, and where the modular roofing panels include one or more openings to allow the modular roofing panel to be secured to an underlying roof support structure. In particular, by having a connection that passes through the modular roofing panel, the modular roofing panel can be clamped between the cover member and the roof support structure, ensuring a strong connection, and a roof that is easy to assemble. It may be that the first region of the modular roofing panel is to provide an outer surface of the pitched roof when the modular roofing panel is provided to partially overlay one or more further modular roofing panels to form the roof. It may be that one portion of the first region is to provide an outer surface of the roof, and another portion of the first region is to be overlayed by another modular roofing panel. In both cases, openings in the first region continue through any other modular roofing panels on which the modular roofing panel is overlayed, or where the other modular roofing panel overlays the modular roofing panel. Thus, in arrangements such as this, the cover member clamps two overlapping modular roofing panels to the roof support structure, and closes openings in both modular roofing panels. It may be that at least one roof sealing member is provided between the cover member and the modular roofing panel. Thus, it may be that a weathertight seal is ensured to reduce or even prevent ingress of water through the modular roofing panel through the opening. Any of the roof sealing member(s) may be formed as a loop. In some examples, it may be that a sealant paste is configured to be provided to form the roof sealing member once set during installation. Unlike roofing tiles which can be nailed onto the roof through holes in the tiles, the openings in the modular roofing panel are not covered by a further modular roofing panel installed thereon. In contrast, in previous roofing tiles, any holes in an underlying tile are covered by the tiles of the row above. The one or more openings may be a plurality of openings. The plurality of openings may be more than two openings, such as four openings. The or each of the one or more openings may each be at least 0.0004 square metres (4 square centimetres, such as a 2cm by 2cm square opening). The or each of the one or more openings may each be at least 0.0016 square metres (16 square centimetres, such as a 4cm by 4cm square opening). The or each of the one or more openings may each be no more than 0.04 square metres (400 square centimetres, such as a 20cm by 20cm square opening). The or each of the one or more openings may each be no more than 0.01 square metres (100 square centimetres, such as a 10cm by 10cm square opening). In other words, the holes are larger than nail-holes, but not so large as to permit access through the opening. Where there are a plurality of openings, the openings may be distributed on opposite sides of a central axis of the modular roofing panel. In other words, where there are at least two openings, a first opening is provided in a left region of the modular roofing panel, and a second opening is provided in a right region of the modular roofing panel. Alternatively or additionally, one opening may be provided in an upper region of the modular roofing panel and a further opening may be provided in a lower region of the modular roofing panel. Thus, the modular roofing panel can be secured effectively to the roof support structure using cover members over each of the openings, and to which the roof support structure is secured. It may be that the first region includes the left region and the right region. At least one of the one or more openings may be divided into a first sub-opening and a second sub-opening by a bridging member. The at least one of the one or more openings may be each of the openings. For the avoidance of doubt, it will be understood that any sub-openings to be covered by the same cover member are considered part of the same opening in the modular roofing panel. It may be that the cover member and the bridging member are together configured such that the cover member contacts the bridging member to secure the modular roofing panel to the roof support structure. Alternatively or additionally, it may be that the bridging member is arranged to contact the roof support structure when the modular roofing panel is secured to the roof support structure. Thus, the load to secure the modular roofing panel to the roof support structure can be spread onto the bridging member. A distance across the bridging member, between the first sub-opening and the second sub-opening, may be less than 0.1 metres. The width may be greater than 0.005 metres. It may be that the bridging member extends between a lower end of the opening and an upper end of the opening. It will be understood that the lower end of the opening is nearer the portion of the modular roofing panel to be closer to a lower edge of the pitched roof than the upper end. In other words, the upper end of the opening is nearer the portion of the modular roofing panel to be closer to a ridge of the pitched roof than the lower end. To put it another way, the bridging member can be considered to run up the modular roofing panel. In other examples, it may be that at least one of any plurality of bridging members is arranged to run laterally across the modular roofing panel. The bridging member may be provided inwardly of the first region of the modular roofing panel. In other words, the bridging member may be recessed within the modular roofing panel relative to the first region of the modular roofing panel providing the outer surface of the pitched roof. The modular roofing panel may define an upstand region around at least one of the plurality of openings, extending outwardly from the roof. In other words, the upstand region may protrude proud of the modular roofing panel relative to the first region of the modular roofing panel. Thus, water ingress through the opening can be reduced or even eliminated due to the provision of an upstand region. It may be that the upstand region comprises a ledge portion for contact by the cover member, via which the modular roofing panel can be secured to the roof support structure. The ledge portion may be substantially parallel to the first region of the modular roofing panel. The upstand region may extend at least 0.02 metres from the first region of the modular roofing panel. The upstand region may extend at least 0.05 metres from the first region. The upstand region may extend no more than 1 metre from the first region. The upstand region may extend no more than 0.3 metres from the first region. The modular roofing panel may comprise a water diversion member arranged to be upstream of one or more (e.g each) of the opening(s) when formed into a pitched roof. Thus, at least some of the water that would otherwise run over the portion of the modular roofing panel in which the opening is defined would be diverted elsewhere, so as to improve the roof’s resistance to water ingress through the opening(s). The water diversion member may be the upstand region. It may be that the water diversion member is separate to the upstand region. The modular roofing panel may further comprise a ridge region to provide a ridge of the pitched roof. Thus, the formation of a roof is simplified because the modular roofing panel already includes another essential element of a pitched roof, the ridge region. The modular roofing panel may further comprise a gutter region to provide a gutter of the pitched roof. Thus, the formation of a roof is simplified because the modular roofing panel already includes another common element of a pitched roof, the gutter region. In some examples, the modular roofing panel may comprise both the ridge region and the gutter region. Thus, the modular roofing panel includes all main parts of a roof on at least one side of a pitched roof. This in itself is believed to be novel and so, in accordance with another aspect of the present inventions, there is provided a modular roofing panel, configured to cooperate with one or more further modular roofing panels having substantially the same shape as the modular roofing panel, to form a roof (e.g. a pitched roof). The modular roofing panel comprises: a first region to define an outer surface of the roof; and a ridge region to provide a ridge of the roof. The modular roofing panel may further comprise a gutter region to provide a gutter of the roof. In accordance with another aspect of the present inventions, there is provided a modular roofing panel, configured to cooperate with one or more further modular roofing panels having substantially the same shape as the modular roofing panel, to form a roof (e.g. a pitched roof). The modular roofing panel comprises: a first region to define an outer surface of the roof; and a gutter region to provide a gutter of the roof. The ridge region may be configured to cooperate with a ridge region of at least one of the further modular roofing panels such that the ridge of the pitched roof is provided by the ridge regions of at least two modular roofing panels. The at least one of the further modular roofing panels may be connected to the modular roofing panel via the ridge regions of both the at least one further modular roofing panel and the modular roofing panel, but on an opposite pitch of the pitched roof to the modular roofing panel. The ridge regions of the modular roofing panel may be arranged to overlap with the ridge region of one of the further modular roofing panels to provide the ridge of the pitched roof. Thus, the ridge regions cooperate by overlapping. It may be that the shape of the ridge region allows the ridge region of a lower modular roofing panel to nest within the ridge region of an upper modular roofing panel to be installed onto the lower modular roofing panel. The ridge region may define an arc of a circle. The arc may have a constant radius of curvature around at least 10 degrees of the arc. The arc may have a constant radius of curvature around less than 180 degrees of the arc. The arc may have a constant radius of curvature around less than 100 degrees of the arc. Thus, a pitch of the roof can be altered, but the ridge regions can still cooperate to form a ridge of the pitched roof. It may be that the ridge region defines an angular shape having an acute ridge portion. The ridge region may have a different profile to the gutter region. The modular roofing panel may comprise a first side overlap region, at a first lateral side of the modular roofing panel, and a second side overlap region, at a second lateral side of the modular roofing panel, away from the first lateral side. The first side overlap region of a first modular roofing panel may be configured to cooperate with (e.g. overlap) a second side overlap region of a second modular roofing panel. The first side overlap region of a first modular roofing panel may be configured to cooperate with (e.g. overlap) a second side overlap region of a second modular roofing panel when the first modular roofing panel is installed next to (e.g. partially overlayed on) the second modular roofing panel. The first side overlap region and the second side overlap region may each comprise at least one of a hill portion and a trough portion. It may be that the openings are together provided in the first side overlap region and the second side overlap region. The gutter region may have at least one of: a fastener member provided at, and an opening defined in, one or both of a first lateral end and a second lateral end. The first lateral end is at the first lateral side of the modular roofing panel. The second lateral end is at the second lateral side of the modular roofing panel. Thus, adjacent gutter regions can be connected together to reduce or even substantially prevent escape of water at the joint between two gutter regions. The gutter region may be for connection to one or more downpipes. It may be that the gutter region is arranged so as to allow liquid to run between a first lateral end and a second lateral end. Thus, there may be no flow obstacles within a central channel of the gutter region that would prevent even a small amount of water flowing therethrough. Any of the fasteners described herein may be fir tree clips. The modular roofing panel may be formed substantially as a sheet material, having a substantially uniform thickness. The first region and at least one of the ridge region and the gutter region may be integrally formed. Thus, the first region at the at least one of the ridge region and the gutter region can be provided by a single piece, manufactured together. The modular roofing panel may have a length (up the roof) of at least 0.5 metres, such as at least one metre. The modular roofing panel may have a width (laterally across the roof) of at least 0.3 metres, such as at least 0.5 metres. It may be that each of the openings in the modular roofing panel is arranged such that they can be reached by a user standing at a gutter region of the modular roofing panel (or at an end of the modular roofing panel where no gutter region is provided). In other words, the cover members can be inserted through the openings without requiring a user to be above the modular roofing panels, making installation safer. A or the roof support structure on which the modular roofing panel is to be supported when formed into a pitched roof may be formed from a plurality of pole members connected by joint members. The roof support structure may be formed from a scaffolding arrangement. The pole members may be scaffolding poles. The joint members may be scaffolding joints. The present invention extends to a kit of parts for forming a pitched roof, the kit of parts comprising the modular roofing panel and the cover members. Each cover member may define a strap passage below an upper surface of the cover member. The strap passage may provide a route for a strap to be provided therethrough, for securing the cover member to the roof support structure via the strap. Thus, a strap can be used to secure the modular roofing panel to the roof support structure, when an installer is beneath the roof. This means that the installer need not work at height to secure the modular roofing panel to the roof support structure. It may be that the strap is a long strap reachable from the ground when the roof is on top of the roof support structure. The kit of parts may comprise the strap. A long strap may hang down by at least one metre from the roof. The strap may a webbing strap. The strap may comprise a clip to secure the strap in a loop. The clip is configured to resist or even prevent lengthening of the loop unintentionally. The clip may be a friction clip. The clip may be a D-clip. It may be that the pitched roof can be assembled without tools. Each cover member may comprise a resiliently deformable clip member. The resiliently deformable clip member may be configured to receive a pole of a roof support structure therein and to releasably retain the pole therein. The resiliently deformable clip member may comprise a first clip arm, arranged to resiliently deform, and opposing a second clip arm. It may be that the resiliently deformable clip member is configured to receive the pole of the roof support structure between the first clip arm and the second clip arm. Thus, the cover member can be retained against the roof support structure. The kit of parts may comprise the roof sealing member(s). The present invention extends to a structure comprising at least one of: the frame assembly; and the pitched roof formed from the modular roofing panel or from the kit of parts comprising the modular roofing panel. The present invention extends to a kit of parts for forming the structure, the kit of parts comprising the kit of parts for forming the roof, and one or more modular building blocks. It may be that the kit of parts comprises everything required to form the structure, including all fastenings. It may be each of the components of the kit of parts can be packed onto a pallet sized to be transportable by commercial air freight. It may be that all of the components of the kit of parts can be packed together onto a single pallet sized to be transportable by commercial air freight. It will be understood that commercial air freight is the freight carried by commercial airliners carrying passengers. In other words, when packed, it may be that the height of the pallet comprising all components necessary to form the structure is no higher than 1.6 metres, such as no higher than 1.5 metres. A width of the pallet may be no wider than 1.5 metres, such as no wider than 1.25 metres. A length of the pallet may be no longer than 3 metres, such as no longer than 2.1 metres. The pallet may be a liftable pallet. The invention extends to a pallet packed with the kit of parts for forming the structure. It may be that the kit of parts for forming the structure comprises at least four modular roofing panels, such as six modular roofing panels. The kit of parts may comprise at least 100 modular building blocks, such as at least 200 modular building blocks, such as 248 modular building blocks. The kit of parts may comprise at least two frame assemblies, such as at least two window frame assemblies, for example four window frame assemblies. The kit of parts may comprise at least one door frame assembly such as exactly one door frame assembly. The structure formed from the kit of parts may have a total width of at least 2 metres, such as 2.7 metres. The structure formed from the kit of parts may have a total length of at least 3 metres, such as 4.3 metres. The walls of the structure formed from the kit of parts may have a height of at least 1.8 metres, such as 2.3 metres. Unless expressly prohibited or otherwise incompatible, it will be understood that features described with reference to the first frame and / or portions thereof are to be considered disclosed in or with reference to the second frame, even if not explicitly described as such herein.

Detailed Description of Example Embodiments Figure 1 shows part of a structure 110 having a wall 1 with a frame assembly 200 installed therein. In this embodiment, the frame assembly relates to a window frame assembly 200. Figure 2 and Figure 3 show the window frame assembly 200 in more detail. As shown in Figure 1, the window frame assembly 200 frames an opening 5 defined in the wall 1, the wall 1 being formed from modular building blocks 3. The window frame assembly 200 comprises a first frame 201 having a first frame inner portion 203, a first frame outer portion 205, and a first frame intermediate portion 207 extending between the first frame inner portion 203 and the first frame outer portion 205. The window frame assembly 200 also comprises a second frame 211. In this embodiment, the second frame 211 has the same shape as the first frame 201. The second frame has a second frame inner portion 213, a second frame outer portion 215, and a second frame intermediate portion 217 extending between the second frame inner portion 213 and the second frame outer portion 215. The window frame assembly 200 further comprises a window pane 220, sandwiched between the first frame 201 and the second frame 211 to allow light to pass through the window frame, whilst reducing the passage of air and or water therethrough. The window pane 220 is formed from a transparent plastics material, such as Perspex ®. Although not visible, a sealing member is provided between an undersurface of the first frame outer portion 205 and the wall 1, and between an undersurface of the second frame outer portion 215 and the wall 1. Figure 3 shows a cross section through the window frame assembly 200 to show how the first frame 201 and the second frame 211 are connected. As shown, the first frame inner portion 203 is secured to the second frame inner portion 213 via inner frame fasteners 209 (also shown in Figure 2). The window pane 220 is sandwiched between the first frame 201 and the second frame 211. In this embodiment, the first frame outer portion 205 comprises an edge region 221 which will be angled away from the wall surface when the window frame assembly 200 is installed as shown in Figure 1. The second outer portion 215 also comprises an edge region 223 angled away from the wall surface when assembled. Figure 4 shows the first frame 201, separate from the window frame assembly 200. Apertures 219 for receiving inner frame fasteners 209 are provided around the first frame inner portion 203. To install the window frame assembly 200 in the wall 1, the first frame 201 and second frame 211 are connected at their inner portions 203, 213, with the window pane 220 therebetween, using the inner frame fasteners 209. As shown in Figure 1, the first frame outer portion 205 extends away from the opening 5 and over part of the surface of the modular bricks (i.e., over part of the surface of the wall 1). Although not shown, the first frame outer portion 215 will also extend away from opening 5 and over a second surface of the wall 1 facing away from the surface visible in Figure 1. In this way, the window frame assembly 200 is securely retained in the wall 1 to frame the opening 5. Figure 5 shows part of a structure 120 comprising a wall 2 and having a frame assembly 300 installed therein. In this embodiment, the frame assembly 300 facilitates the provision of an access member (e.g., a door) through the wall 2. That is, the frame assembly 300 is a door frame assembly 300. Figure 6 shows the door frame assembly 300 separate from the wall 2 and Figure 7 shows a cross-section through the door frame assembly 300. As shown in Figure 5, the wall 2 is formed from modular building blocks 4. The access member can be used to selectively permit access through an opening defined in the wall 2. The access member comprises an upper door member 306a and a lower door member 306b - this further degree of modularity facilitates easier transport. In this embodiment, there is no layer of modular building blocks between the access member and the ground. In other embodiments, providing a layer of modular building blocks beneath the access member may be advantageous - e.g., if the ground below the structure is frequently waterlogged, such that a raised floor of the structure is to be provided. Outer frame fasteners 360 are used to secure the door frame assembly 300 to the wall 2. The door frame assembly 300 comprises a first frame 301 having a first frame inner portion 303, a first frame outer portion 305, and a first frame intermediate portion 307 extending between the first frame inner portion 303 and the first frame outer portion 305. The door frame assembly 300 also comprises a second frame 311 having the same shape as the first frame 301. The second frame has a second frame inner portion 313, a second frame outer portion 315, and a second frame intermediate portion 317 extending between the second frame inner portion 313 and the second frame outer portion 315. Each of the first frame outer portion 305 and second frame outer portion 315 have openings 330 to receive outer frame fasteners 360. When assembled, the first frame inner portion 303 is secured to the second frame inner portion 313 via inner frame fasteners 309. A first hinge 320a and a second hinge 320b are both mounted between the first frame inner portion 303 and the second frame inner portion 313. In this embodiment, the access member can be secured in a closed position using a first locking bolt (not shown) movable into a first lock recess 322a and a second locking bolt (not shown) movable into a second lock recess 322b. The first frame inner portion 303 and second frame inner portion 313 are shaped to allow these hinges and locks to be accommodated. Figure 8 shows how a portion of each of the first frame inner portion 303 and second frame inner portion 313 are shaped so that a region for accommodating the hinge 320a is provided therebetween. The hinge 320a can therefore be securely mounted between the inner portions of each frame. Openings 350 are provided to allow additional fasteners (not shown) to be used to secure the frames to any further components, such as hinge 320a. Figure 9 shows the first frame 301, separate from the doorframe assembly 300. Figure 9 also shows how first frame inner portion 303 can be shaped to provide regions 340 for further components (such as locks and hinges). Apertures 319 for receiving inner frame fasteners 309 are provided around the first frame inner portion 303. Figure 10 shows a pitched roof according to an example of the present disclosure, formed from modular roofing panels, and with three of the modular roofing panels shown semi-transparent to provide visibility of the underlying structure. The pitched roof 400 covers a building having four walls 130 (formed from modular building blocks as described hereinbefore). The pitched roof 400 is formed from a plurality of modular roofing panels 410, partially overlapping to form a first pitch 402 of the pitched roof 400 and a second pitch 404. Each pitch 402, 404 is formed from six modular roofing panels 410. The two pitches 402, 404 meet at a peak, defining a ridge region 406. Each pitch 402, 404 terminates in a gutter region 408, at an opposite end of the pitch 402, 404 to the ridge region 406. The modular roofing panel 410 is illustrated and described in more detail with reference to Figures 11A and 11B hereinafter. The modular roofing panels 410 are each secured to a roof support structure 450. The roof support structure 450 is itself secured to the walls 130 and extends from an upper surface thereof. The roof support structure 450 comprises pitched roof support members 452 extending up the pitch of the roof 400, towards the ridge region 406. The roof support structure 450 further comprises ridge members (not visible in Figure 10) extending beneath the ridge region 406, as well as gutter lower members 454 extending parallel to the ridge region 406 above an upper surface of the wall 130, and lower connecting members 456 extending between the gutter lower members 454. The roof support structure 450 further comprises vertical support members 458 extending from the lower connecting member 456 to the ridge member at the ridge region 406. The modular roofing panels 410 are each secured to the roof support structure 450 using cover members 430 which extend through and cover openings defined in the modular roofing panels 410. In this way, the cover members 430 retain the pitched roof 400 in place on the walls 130 of the building. In this example, the pitch of the roof is 27.5 degrees from the horizontal, meaning that an angle between the two pitches at the ridge is 125 degrees. To avoid overcrowding the labelling of Figure 10, it will be understood that not every instance of the components described hereinbefore have been labelled in Figure 10. Figures 11A and 11B show two different views of a modular roofing panel used to form the pitched roof of Figure 10. The modular roofing panel 410 includes a ridge region 412 and a gutter region 414. A main region 416, elsewhere referred to as a first region of the modular roofing panel 410 extends between the ridge region 412 and the gutter region 414. In this instance, the modular roofing panel 410 has defined therein six openings 418a, 418b, 418c, 418d, 418e, 418f, specifically defined in the main region 416. In this example, each of the six openings 418a, 418b, 418c, 418d, 418e, 418f, are substantially identical in shape and configuration. The first opening 418a is provided towards the ridge region 412 of the modular roofing panel 410, and towards a first side of thereof. The second opening 418b is provided towards the ridge region 412 of the modular roofing panel 410, and towards a second side of thereof. The third opening 418c is provided towards a mid-point between the ridge region 412 of the modular roofing panel 410 and the gutter region 414, and towards a first side of thereof. The fourth opening 418d is provided towards the mid-point between the ridge region 412 of the modular roofing panel 410 and the gutter region 414, and towards a second side of thereof. The fifth opening 418e is provided towards the gutter region 414 of the modular roofing panel 410, and towards a first side of thereof. The sixth opening 418f is provided towards the gutter region 414 of the modular roofing panel 410, and towards a second side of thereof. The modular roofing panel 410 further comprises a plurality of surface protrusions 420a, 420b, 420c, 420d in an upper surface thereof, extending from the ridge region 412 through the main region and to the gutter region 414. The modular roofing panel 410 is formed as a sheet, with a substantially uniform thickness throughout. A protrusion on an upper surface of the modular roofing panel 410 therefore corresponds to a depression on an undersurface of the modular roofing panel 410. The ridge region 412 comprises a pitch-side portion 413a extending into the main region 416 of the modular roofing panel 401 and a far portion 413b extending away from the main region 416. An angle between the pitch-side portion 413a and the far portion 413b is 125 degrees. In this way, it can be understood that the modular roofing panels 410 having the ridge region 412 in this example is suitable to form a pitched roof having a pitch of 27.5 degrees. The modular roofing panel 410 further comprises a plurality of further protrusions to accommodate junctions of the roof support structure, as best illustrated in other figures herein. The region of the modular roofing panel surrounding the openings 418a, 418b, 418c, 418d, 418e, 418f includes an upstand and a bridging member, as best described with reference to Figure 11C, which shows opening 418b. Figure 11C shows a close-up view of the opening 418b in the modular roofing panel 410 of Figures 11A and 11B. Although the opening 418b is the second opening 418b described hereinbefore with reference to Figures 11A and 11B, the features to be described are applicable to each of the openings in the modular roofing panel 410. The opening 418b is divided into a first sub-opening 422a and a second sub-opening 422b by a bridging member 424. The portion of the modular roofing panel 410 defining the opening 418b comprises an upstand region 426, extending outwardly from the modular roofing panel 410. The upstand region 426 extends outwardly from the modular roofing panel 410 by 0.02 metres. The portion of the modular roofing panel 410 defining the opening 418b further comprises a recess region 428, extending inwardly from the upstand region 426 by 0.04 metres. The bridging member 424 extends between a recessed end of the recess region 428 in a direction transverse to a ridge direction of the modular roofing panel 410. In this example, a planar cap region provides a flat surface between the recess region 428 and the upstand region 426. Figure 12 shows a close-up of a region of the pitched roof 400 of Figure 10. A first modular roofing panel 410a is shown in solid render. A second modular roofing panel 410b is shown in transparent render, allowing interactions between the second modular roofing panel 410b and other components of the pitched roof 400 to be visible for illustrative purposes. As can be seen, the first modular roofing panel 410a is installed on the roof support structure 450 on a first pitch of the roof. The second modular roofing panel 410b is installed on the roof support structure 450 such that the ridge region 412b of the second modular roofing panel 410b overlays the ridge region 412a of the first modular roofing panel 410a. In this way, the ridge of the pitched roof 400 is formed by the ridge regions 412a, 412b of both the first and second modular roofing panels 410a, 410b. Cover members 430 are provided to close the openings defined in the modular roofing panels 410a, 410b and extend through the modular roofing panels 410a, 410b to secure to the roof support structure 450. As will be appreciated, the cover members 430 function to seal the openings in the modular roofing panels 410a, 410b to reduce or even prevent ingress of water therethrough. Further explanation of the form and operation of the cover members 430 is provided with reference to Figures 13 to 15 hereinafter. Figure 13 shows a cover member used in the pitched roof of Figure 10. The cover member 430 comprises a cap portion 432 and two clip members 434, 436 extending substantially normal from the cap portion 432. The cap portion 432 extends to prevent passage of the cover member 430 through the openings in the modular roofing panel 410. The cover member 430 further provides a lower surface 438 facing away from an upper surface of the cap portion 432 to contact against the bridging member 424 of the openings in the modular roofing panel 410, described with reference to Figure 11C hereinbefore. The two clip members 434, 436 include a first clip member 434 and a second clip member 436. An inner surface 435, 437 of each clip member 434, 436 defines a concave profile, to retain a cylindrical pole of the roof support structure 450 therebetween. The clip members 434, 436 are each resiliently deformable to allow the cover member 430 to be deformed temporarily to push onto the poles of the roof support structure 450, and then push back towards each other once the pole is within the portion of the inner surface defining the concave profile, as will be described further with reference to Figures 14 and 15 hereinafter. Figure 14 shows a cross-section through the cover member 430 of Figure 13, when used to secure a modular roofing panel 410 to a roof support structure 450. A roof sealing member 440 is provided between the cover member 430 and the modular roofing panel 410. Specifically, the roof sealing member 440 is provided between an underside of the cap portion 432 and the planar cap region 427 between the recess region 428 and the upstand region 426. Additionally, a strap 460 is provided passing through a strap passage 439 defined below the cap portion 432 of the cover member 430. Although not shown in Figure 14, the strap 460 can be closed beneath the pole of the roof support structure 450, by passing through a strap clip. As the strap 460 is tightened, this pulls the cover member 430 down towards the pole of the roof support structure 450, which acts to pull the modular roofing panel 410 down towards the roof support structure 450. In this way, the modular roofing panel 410 is secured to the roof support structure 450. Figure 15 shows another view of the cover member of Figure 14, from a different angle, with some components shown semi-transparent to aid visibility. Again, the strap 460 is shown open, but would be closed in use to form a loop and pull the cover member 430 towards the pole of the roof support structure 450. Figure 16 shows a flowchart illustrating a method of assembling a wall including a frame assembly. The method 500 comprises a first step of assembling 510 a wall of modular building blocks, having an opening defined therein. The opening is sized to match the frame assembly. The method 500 further comprises a second step of inserting 520 a first frame of the frame assembly into a first side of the wall, such that a first frame inner portion extends into the opening. The method 500 further comprises inserting 530 one or more intermediate components (e.g. a window pane for a window frame assembly, or one or more hinge members) against the first frame inner portion, and inserting 540 a second frame of the frame assembly into a second side of the wall, opposite the first frame. Finally, the method 500 comprises securing 550 the first frame to the second frame via the first frame inner portion and the second frame inner portion to form the frame assembly retained in the opening in the wall. The one or more intermediate components remain between the first frame inner portion and the second frame inner portion. Figure 17 shows a flowchart illustrating a method of assembling a pitched roof including the modular roofing panels of Figures 11A and 11B. The method 600 comprises a first step of assembling 610 a wall of a structure. The walls are formed from modular building blocks. The method 600 further comprises assembling 620 a roof support structure. The roof support structure is formed from scaffolding poles, joined by connectors to provide the support for a pitched roof. The roof support structure can be connected to the walls of the structure, typically later during assembly of the pitched roof. The method 600 further comprises providing 630 a first modular roofing panel on a first pitch of the pitched roof, providing 640 a second modular roofing panel on the first pitch of the pitched roof, partially overlapping with the first modular roofing panel. The first modular roofing panel and the second modular roofing panel each have openings defined therein which align to provide a through-opening in an overlap region of the first modular roofing panel and the second modular roofing panel. The method 600 further comprises inserting 650 a cover member through the opening in the overlap region of the first modular roofing panel and the second modular roofing panel and securing 660 the cover member to the roof support structure. The method 600 may further comprise repeating this with further modular roofing panels on the first pitch to extend the width of the roof. The method 600 typically further comprises providing another further modular roofing panel on a second pitch of the pitched roof. The another further modular roofing panel comprises a ridge region to overlap with a ridge region of the first modular roofing panel to form a ridge of the pitched roof. Typically, the modular roofing panels are formed from sheet plastics material, and are integrally formed. In summary, there is provided a kit of parts to form a frame assembly (200, 300) for framing an opening (5) defined in a wall (1, 2) of a structure (110,120), the wall formed from modular building blocks (3, 4).
