Description

[Technical Field]

[0001] The present disclosure relates to a multi-storey building having an exterior facade and a method for erecting or assembling the building and facade. [Background technology]

[0002] It is known to utilize prefabricated modular elements for the facade of a multi-story building that are attached to the multi-story building after the building is erected. In some configurations, known methods of constructing a multi-story building require safety rails or scaffolding to add prefabricated facade elements to floors at any height of the building to provide the building's walls and, in some configurations, windows. Known methods of erecting a multi-story building include the steps of: i) erecting scaffolding or perimeter screen; ii) erecting supports that extend upward from the ground or slab; iii) constructing formwork for the upper floor; iv) forming the upper floor; v) repeating until the building is at the required height; vi) removing the scaffolding or perimeter screen; and vii) attaching the exterior facade to the building. Alternatively, known methods may include erecting safety rails on any floor of the multi-story building and utilizing harnesses to prevent falls.

[0003] Where prior art is referenced herein, it should be understood that such reference is not an admission that the prior art forms part of the common general knowledge in the art in Australia or anywhere else. Summary of the Invention

[0004] In its broadest sense, a method for erecting a multi-story building is disclosed in which the facade is installed before the floors are installed. As such, this methodology reverses the traditional approach of constructing the building's floor structures first and then attaching the facade to the floor structures. Furthermore, the interior structure can be efficiently constructed from the inside out, with the facade forming a safety barrier envelope during construction.

[0005] The construction process can follow an iterative approach such that part of the facade is installed, a floor is erected, the facade is extended, and then the next floor can be erected.

[0006] This method has the advantage of allowing multi-story buildings to be constructed without the need to erect scaffolding or perimeter screens, which can save material costs during construction and significantly improve construction time. Because the facade precedes the construction of the multi-story building, allowing at least one subsequent floor to be erected within the facade envelope, a new construction process is provided that speeds up floor construction, eliminating the need to install separate safety barriers while the floor is being installed, while allowing construction crews and equipment to be built from inside the building to erect the subsequent floor. Furthermore, the facade may provide integrated connectors that allow subsequent floors to be quickly connected to the facade.

[0007] In one aspect, disclosed is a method of erecting a multi-story building having a facade disposed around at least a portion of the periphery of the multi-story building, wherein during construction at least a portion of the facade is positioned to extend at least two storeys above an upper work area of ​​the building and forms at least a portion of a safety barrier for that work area, and in erecting the multi-story building at least one further floor of the building is erected above the upper work area, the or each further floor forming a respective subsequent upper work area of ​​the building, and at least a portion of the facade is positioned to extend at least one storey above the top of the subsequent uppermost work area and forms at least a portion of the safety barrier for that topmost subsequent work area.

[0008] In some configurations, the floor or each further floor is formed such that the floor connects to the facade.

[0009] In some forms, once the top subsequent work area is formed, the facade is increased in height to extend at least two stories above the top subsequent work area, allowing at least one additional floor of the structure to be erected while providing a safety barrier for its construction.

[0010] In a further aspect, a method of constructing a multi-story building is disclosed, the method comprising: positioning a first facade assembly around at least a portion of the perimeter of the multi-story building, the facade assembly comprising a facade structure of at least one story height, the facade structure positioned so that it extends upwardly over an upper work area of ​​the building and forming part of a safety envelope for that work area; positioning a second facade assembly so that it extends upwardly from the first facade assembly, the second facade assembly comprising a second facade structure; and connecting a floor to at least one of the first facade assembly and the second facade assembly such that the floor forms a top floor erected above the upper work area.

[0011] In some configurations, a further facade assembly is positioned to extend upwardly from the second facade assembly such that an exterior facade of at least two storeys height extends above the top floor.

[0012] Also disclosed is a facade assembly configured to be positioned around at least a portion of the periphery of a multi-story building during construction and arranged to extend beyond an upper work area of ​​the building and form part of a safety envelope for that work area, the facade assembly further configured to be connected to at least one further floor erected above the upper work area, the facade assembly including a facade building configured to connect to at least one further facade assembly disposed above the facade building.

[0013] In some configurations, the facade assembly includes a support system that supports the facade construction before connecting additional floors to the facade assembly.

[0014] In some configurations, the support system is adjustable to allow for angular adjustment of the facade construction relative to the upper work area.

[0015] In some embodiments, the facade is formed from a plurality of panels, and the panels form at least a portion of the safety barrier.

[0016] In some forms, the facade is formed as a framework. In some forms, the framework is formed from multiple frames connected to each other. In some forms, the frames form part of the facade panels. In other forms, these frames are formed as part of interconnected modules (with more three-dimensional shapes).

[0017] The advantages of using frame construction for facades are that they have a higher strength-to-weight ratio than panels, can be arranged to be easily connected to each other (using mechanical fasteners and the like), and can support a variety of infill materials and constructions. For example, the infill can be windows or doors, or replaceable barrier materials. The frames can also be used to support or carry other components such as services, loading platforms, balconies, and the like.

[0018] In one form, the modules are freestanding, which has the advantage of allowing for faster construction of the facade, eliminating the need for props and the like.

[0019] In some configurations, the facade assembly may include temporary support members that are used during initial installation and floor construction, but that are removed after the floors are erected and therefore do not form part of the final building structure. These temporary supports may allow the facade assembly to stand on its own while it is being installed.

[0020] A method of constructing a multi-story building is also disclosed, the method comprising positioning a first facade assembly around at least a portion of the perimeter of the multi-story building, the facade assembly being in the form of a module and including a facade construction at least one story high, the facade construction being positioned so that it extends upwardly over an upper work area of ​​the building and forms part of a safety envelope for that work area.

[0021] In some configurations, the facade assembly modules are freestanding and configured to be placed alongside and on top of other facade assembly modules.

[0022] In some configurations, the facade panels or modules are arranged so that they are on the order of floor height of the building, which, depending on the height, can be on the order of 3 to 4 meters, but in certain circumstances can be higher or lower depending on the design specifications of the building.

[0023] Where the facade assembly is a more modular structure, the modules may come in a variety of depths. In some configurations, these depths are 300 mm, 600 mm, 1.2 m, or 2.4 m. In some configurations, the modules may form part of the remaining floor construction of the building.

[0024] In some embodiments, the building floor is positioned to rest on the upper or lower edges of the panels or modules. In some embodiments, the floor may span the joints between adjacent panels. In some embodiments, the facade assembly may include connectors to facilitate connection of the floor to the facade.

[0025] This method has the advantage that multi-storey buildings can be constructed without the need to erect expensive scaffolding or perimeter screens. This method also has the advantage of increasing safety, as the facade acts as a perimeter screen or scaffolding to prevent falls from the structure. This method means that the scaffolding can essentially be integrated with the exterior or facade of the building.

[0026] In some configurations, the facade panels are made of a material strong enough to function as a permanent facade, including fall protection and windows.

[0027] In some configurations, the facade panels prevent people from falling off the structure during and after construction.

[0028] Embodiments will now be described, by way of example only, with reference to the accompanying drawings in which: [Brief explanation of the drawings]

[0051] This method allows workers to work safely in the upper work area without the need for a separate fall barrier or scaffolding. The facade assembly is designed so that during construction, at least a portion of the facade panels forming the facade extend above any work area to prevent falls from the work area.

[0052] In some configurations, the upper floor connection members include hooks or bars or other types of connections that extend from the inner surface of the facade assembly.

[0053] In some configurations, the upper floor connections are welded to the facade assembly.

[0054] In some configurations, the upper floor connections are bolted to the facade assembly.

[0055] In some embodiments, the method further includes attaching lower edges of the plurality of second story facades to upper edges of the plurality of facade panels.

[0056] In some configurations, the facade panels are positioned adjacent to one another.

[0057] In some embodiments, the facade panels are made of structural steel. In some embodiments, the facade panels include ventilation openings. In some embodiments, the facade panels are in the form of slats, grids, or perforated steel. In some embodiments, the facade panels are decorative.

[0058] In some embodiments, the facade panel includes a structural frame and an exterior surface that engages with the structural frame. In some embodiments, the exterior surface is waterproof. In some embodiments, the facade panel further includes an interior surface that engages with the structural frame. In some embodiments, insulation is disposed between the exterior surface and the interior surface. In some embodiments, the facade panel includes a window or glass.

[0059] In some embodiments, the facade assembly is formed as a modular frame structure having an inner frame and an outer frame. In some embodiments, the facade structure is formed on the outer frame. In some embodiments, the facade structure is formed on the inner frame, and the outer frame is configured to be an exterior feature of the building.

[0060] In some forms, the facade panels may be solid composite panels.

[0061] In some embodiments, the facade panel or module is made of aluminum, glass, a combination of aluminum and glass, aluminum, composites, concrete, steel, steel and glass, or other construction materials. In some embodiments, the facade panel or modules can be load-bearing. In some embodiments, when the panels are load-bearing, they are made of concrete, structural steel, or other load-bearing materials.

[0062] In some configurations, the panels are configured to function as a fall protection system and a permanent facade for the structure.

[0063] 1, a method for constructing a building having a facade, such as a multi-story parking garage, apartment complex, high-rise structure, etc. In the illustrated form, the multi-story building may be a parking garage.

[0064] As shown in Figure 1A, facade assembly 10 is being installed on top of previously installed facade assembly 11, with 10 and 11 joining to form a two-story facade assembly that stands upright and extends upward from upper floor 17. Once facade assembly 10 is installed, the exterior facade 100 of the entire building extends two stories above the top floor.

[0065] The facade assembly 10 is installed as a module and includes a facade construction 12 (in the form of steel panels) and a lower horizontal section 13. The facade assembly also includes a support construction 15, which includes supports and columns for supporting and aligning the facade assembly.

[0066] The facade assembly 10 further includes a connector 16. In the illustrated form, the connector is in the form of a rebar extending outwardly from the lower horizontal portion 13.

[0067] An upper work area 17 is located on the top floor. The facade assembly extends two floors above the work area 17.

[0068] As shown in FIG. 1B, once the modules 10 are installed, an additional floor 18 is constructed above the upper work area 17 and connected to the facade assembly with connectors 16. Additional temporary supports 22 may be included when constructing the floor. In the illustrated embodiment, the connectors extend to the connection between the facade assembly 10 and the previously installed facade assembly 11. The connectors 16, in the form of rebar, are encapsulated in concrete and poured as the upper floor 18 is constructed. Also, as shown in FIG. 1B, the supports 15 may be temporary in some embodiments and may be removed.

[0069] As shown in Figure 1C, once the new top floor is constructed, a further facade assembly 21 is placed on top of the facade assembly 10, with the exterior facade 20 remaining two storeys above the top floor.

[0070] As each subsequent floor is erected, the temporary supports that form part of the facade assembly on the floor below are removed, leaving behind the final facade panels 12 and horizontal sections 13 that form part of each floor.

[0071] In the embodiment shown in Figure 1, safety guardrails 19 and wheel chocks 20 may be integrated into the facade assembly.

[0072] The facade assembly shown in the diagram is constructed to be in the order of the floor height of the building. Depending on the height, this may be in the order of 3 to 4 metres, but in certain circumstances it may be higher or lower depending on the design specifications of the building.

[0073] Where the facade assembly is a more modular construction as shown, the modules may come in a variety of depths, in some configurations these depths being 300mm, 600mm, 1.2m or 2.4m.

[0074] In some configurations, these modules may form part of the construction of the remaining floors of the building. In the case of Figures 1a to 1C, the facade assembly is arranged to have a depth of approximately 1.2 m.

[0075] The facade assemblies 10, 11 can be delivered to the site as an integrated unit and hoisted into place as a single unit. Temporary supports for the frame assembly are required while it extends over the upper work area, but once the floors are installed, the temporary supports are removed, leaving the facade, floors, and other fixtures with the structure.

[0076] The multi-story building 10 includes a plurality of facade panels 12 that form the exterior facade 13 of the multi-story building. Floors 14 of the multi-story building are contained within the facade 13. The facade panels 12 include panel engagement portions 15 formed to allow the facade panels 12 to engage with facade panels above and below within the exterior facade 13. The facade panels 12 further include floor connections adapted to connect or engage the floors 14 with the facade panels 12.

[0077] Figure 1 shows one version of a method for constructing a multi-story parking garage or other structure that includes guardrails. Alternative embodiments may be utilized.

[0078] Referring now to Figure 2, one embodiment of a method for constructing a multi-story building having an exterior facade is shown. The multi-story building may include a school, apartment building, office, shopping center, hospital, parking garage, high-rise building, or any type of building. The method includes installing a facade assembly such that a facade panel of the facade assembly extends two stories above the top floor before work is performed on the top floor.

[0079] As shown in FIG. 2A, facade assembly 10 is installed atop previously installed facade assembly 11, joining assemblies 10 and 11 to form a two-story facade assembly that stands above and extends from upper floor 17. Facade assembly 10 includes facade panels 12 and a lower horizontal section 13. The facade assembly also includes a support structure 15, which may be comprised of supports and braces for supporting and aligning the facade assembly. Facade structure 12 may include a support frame 24 and an exterior infill structure, which may be glass or the like, that forms the exterior of the structure.

[0080] The facade assembly shown in Figure 2 is positioned so that it is on the order of floor height of the building. Depending on the height, this may be on the order of 3 to 4 metres, but in certain circumstances it may be higher or lower depending on the design specifications of the building.

[0081] As shown, where the facade assembly is of a more modular construction, the modules may be provided in a variety of depths, in some configurations these depths being 300mm, 600mm, 1.2m, or 2.4m.

[0082] In some configurations, these modules may form the remaining floor construction of the building. In the case of Figures 2A to 2C, the facade assembly is arranged to have a depth of approximately 600 mm.

[0083] The facade assembly 10 further includes a connector 16. In the illustrated form, the connector is in the form of a rebar extending outward from the lower horizontal portion 13.

[0084] An upper work area 17 is provided on the top floor. The facade assembly extends two floors above the work area 17, forming a safety barrier envelope for construction site workers.

[0085] As shown in Figure 2B, an upper floor 18 is constructed above the upper work area 17 and connected to the facade assembly with connectors. In the illustrated configuration, the connectors extend to the connection between facade assembly 10 and previously installed facade assembly 11. Connectors 16 in the form of rebar are encapsulated in concrete and poured as the upper floor is constructed. Also, as shown in Figure 2B, supports 15 are temporary in some configurations and may be removed.

[0086] As shown in Figure 2C, once the new top floor is constructed, a further facade assembly 21 is placed on top of the facade assembly 10, with the exterior facade 20 remaining two storeys above the top floor.

[0087]

[0023] Referring now to Figure 3, a further embodiment of a method for constructing a multi-story building having an exterior facade is shown. The multi-story building may include a school, apartment building, office, shopping center, hospital, parking garage, high-rise building, or any type of building. The method includes installing a facade assembly such that a facade panel of the facade assembly extends two stories above the top floor before work is performed on the top floor.

[0088] As shown in Figure 3A, facade assembly 10 is modular and is installed atop a previously installed facade assembly 11 such that facade assemblies 10 and 11 join to form a two-story facade assembly that stands upright and extends upward from a subfloor 17. Facade assembly 10 includes facade panels 12 and a lower horizontal section 13. The facade assembly also includes a support structure 15 that includes supports and braces for supporting and aligning the facade assembly.

[0089] The facade assembly 10 further includes a connector 16. In the illustrated form, the connector is in the form of a rebar extending outwardly from the lower horizontal portion 13.

[0090] An upper work area 17 is located on the top floor. The facade assembly extends two stories above the work area 17.

[0091] As shown in Figure 3B, an upper floor 18 is constructed above the upper work area 17 and is connected to the facade assembly with connectors. In the illustrated configuration, the connectors extend at the connection between facade assembly 10 and previously installed facade assembly 11. Connectors 16 in the form of rebar are poured and covered with concrete as the upper floor 18 is constructed. Also, as shown in Figure 2B, supports 15 are temporary in some configurations and may be removed.

[0092] As shown in Figure 3C, once the new top floor is constructed, a further facade assembly 21 is placed on top of the facade assembly 10, with the exterior facade 20 remaining two storeys above the top floor.

[0093] The arrangement illustrated in Figures 3A to 3C is similar to that of Figures 2A to 2C, with the main difference being that the facade assembly is wider, approximately 1.2 m.

[0094] If necessary, one or more additional facade assemblies may be erected above an existing installed facade assembly so that the facade extends two or more stories from any floor, in accordance with the design. Because the facade is constructed to provide a safety barrier for workers assembling the building's interior structures and floors, a one-story height is considered sufficient to ensure adequate safety. However, if necessary and within the scope of the disclosed methodology, additional story heights may be provided. Because the height of the extended facade must accommodate wind loads and the like, additional supporting structures will be required, increasing the strength of the facade structure, if further extension of the facade is desired.

[0095] The multi-story building of the present disclosure may be constructed by placing a bottom layer of facade assemblies on the lower or first floor of the building. The bottom layer facade panel may be placed at or above ground level on the first floor of the building, or intermediate between the ground and first floors. The top layer of facade assemblies is placed on top of the bottom layer of facade assemblies. Floor connections 17 are placed on the inner surface of the facade assemblies. Once the facade assemblies for the upper floors are in position, formwork and floor support columns or the like are installed for the floors. Floors are then built, constructed, or poured around the floor connections to engage the floors and facade assemblies. Workers can position the next facade assembly so that the building's exterior facade extends two floors above the top floor. This process continues until the structure has the required number of floors.

[0096] As can be seen, throughout the process, the facade is placed before the upper floors are constructed and extends at least two stories above. This allows the facade to act as a fall protection screen and safely locate the top floor work area on the top floor. Once the project is complete, the facade remains as the exterior wall or facade of the building.

[0097] The floor may be supported by the building. In some configurations, the floor may be supported by the facade panels. In this configuration, the panels are load-bearing and made of a load-bearing material. In other configurations, the floor may be supported by free-standing steel or concrete columns.

[0098] The floor may be made of any flooring material. In some embodiments, the floor is made of precast concrete. In other embodiments, the floor includes steel forms with concrete poured over them. In some embodiments, the floor includes reinforced concrete. In some embodiments, the floor includes structural steel and decking. In some embodiments, the floor includes structural materials, and in some embodiments, the floor is made of composite materials.

[0099] In some embodiments, the panels of the present disclosure may include a panel frame that serves as part of the building's permanent facade with a replaceable infill material mesh. For example, the frame may include removable infill panels that can be replaced with glass or other materials. In other embodiments, the panels may include a frame and wall material that serves as the building's permanent facade, and an interior protective material that can be removed after construction has occurred. For example, the panel may include a glass exterior and a removable board or polymer interior.

[0100] 4 through 10 disclose a method of constructing a multi-storey building, where the facade may be provided in the form of modules 950 or may be incorporated as part of the modules 950. The modules may be adapted to extend around the periphery of the structure to form the facade of the multi-storey building 900, and in some embodiments may form part of the floor space of the building.

[0101] In one illustrated embodiment, the module 950 includes a floor 953 and a plurality of walls extending therefrom. In the embodiment shown in FIGS. 4 through 10, the module 950 has a rectangular parallelepiped outline. In other embodiments, the module may be shaped with a polygonal outline having four or more sides, such as an octagonal outline. In yet another example, configuring octagonally shaped modules in a side-by-side relationship can provide the exterior shape of the multi-story building 900 with, for example, a curved outline. As such, it is anticipated that the shape provided for the module may be dictated by the architectural design of the particular multi-story building. In some embodiments, facade barrier structures (e.g., windows, doors, and / or walls) may be provided on the exterior walls of the module, or may be provided on the interior walls such that the building 500 has an exterior frame, balcony, or the like.

[0102] The modular feature provides additional features over a facade constructed solely from a barrier structure. Therefore, the module may have improved load-bearing capacity, be more stable, and / or provide additional functional requirements (e.g., noise control, heating / cooling, and / or services). The multiple walls within a freestanding module also provide lateral stability to the module. This lateral stability allows the module to be self-supporting, or at least require fewer temporary supports than flat facade elements. In some configurations, the module is substantially freestanding, with additional support provided to adjacent multi-story structures, for example, by ties, braces, etc. In this configuration, ties can be temporarily provided to help support the module during construction of the multi-story structure. This configuration of module offers the advantage of requiring fewer ties compared to individually constructed facade panels, i.e., panels that are not prefabricated as modules.

[0103] In some other configurations, the modules 950 are structured to be independent of the adjacent multi-story building 900, for example, without the need to be attached by ties. Advantageously, this simplifies the construction process by eliminating the need for temporary supports to erect the modules. Consistent with conventional embodiments, the facade modules can be positioned to extend at least two stories above an existing work area (building floor), after which subsequent stories are installed and additional stories of the facade modules are installed to maintain a facade extension of at least two stories. This allows for more efficient construction techniques.

[0104] The module 950 can accommodate structural loads over a larger surface than an individual facade panel, which advantageously provides the module with improved stability during construction of a multi-storey building.

[0105] In some forms, the walls and floors 953 of the modules define interior spaces that can support a variety of functions. Referring to Figure 4, freestanding modules are formed as balcony module 950a, enclosed balcony module 950b, and module without balcony 950c.

[0106] Any configuration of freestanding modules can be provided in a multi-story building, as shown in Figure 4. For example, a module that functions as a balcony can be placed adjacent to a module that functions as an enclosed balcony. The configuration of the modules can be selected according to the particular structural design of the building.

[0107] In some forms, the module 950 can be used to provide shielding for a multi-story building. For example, the interior space defined by the module can be utilized to shield the multi-story building from heat by providing a thermal barrier. It is further contemplated that the module can shield light from entering the multi-story building. Alternatively, the module can be configured to facilitate light penetration into the multi-story building, for example, for natural lighting.

[0108] In some further configurations, the modules may function to support services such as ventilation, air conditioning, electrical wiring, water lines, sewer lines, or drainage lines. Adjacent modules may be configured to provide access between the modules. For example, doorways may be provided between adjacent modules. In another example, adjacent modules are not separated by walls to provide an uninterrupted passageway between the modules.

[0109] The self-supporting modules can be assembled one above the other around the structure 900. As shown in FIG. 4, the modules 950 are configured to be positioned on the multi-story building 900, for example, by a crane. Furthermore, the modules 950 can be transported to the multi-story building work site by truck. The modules have the advantage that they can be transported by both truck and crane in a pre-assembled, self-supporting configuration. This can increase the efficiency of the construction of multi-story buildings. Furthermore, the modules can be installed in single (story) height units or multi-height units, as needed.

[0110] Referring now to Figures 5-10, in some embodiments, module 950 includes a floor 953 and a plurality of walls extending therefrom. In the embodiments shown in Figures 5-7, the floor is a composite floor incorporating rebar (reinforcing bars). In the embodiments shown in Figures 8-10, floor 953 includes rebar (reinforcing bars) 959 formed to be incorporated into a plaster floor. In some embodiments, the floor section can include permanent formwork, while in other embodiments, removable formwork can be utilized. When floor 953 is poured, rebar 959 is installed between floor 953 of module 950 and floor 914 of building 900.

[0111] 5-10, the rebar can be formed to extend from floor 953 as connectors 920 for connecting floor 953 to structure 900. The connectors can be formed and positioned so that after module 950 is placed on structure 900, floor 914 can be poured and the connectors can be incorporated as floor reinforcement.

[0112] 5-10, the walls extending from the floor 953 of the module 950 can take the form of an interior wall 957, an exterior wall 951, and a side wall 956. The interior and exterior walls are spaced apart from one another in a direction away from the building 900. The side wall 956 connects the interior wall 957 and the exterior wall 951.

[0113] In some configurations, and as best shown in Figures 7 and 10, the freestanding module 950 can include additional wall portions 952 for further connection between the inner and outer walls. In other configurations, and as best shown in Figures 5 and 6 and 8 and 9, the outer wall 951, inner wall 957, and side wall 956 can also include a top frame member 911.

[0114] In some configurations, the wall is paneled and may have an exterior surface 947 and an interior surface 949, with a cavity between them that may contain insulation. The exterior surface is typically a waterproof, outward-facing panel and may be made of non-combustible cladding, cement sheet or board, aluminum, or other structural material for the exterior facade of a building. The interior surface is typically an inward-facing panel, i.e., the panel that faces the interior space of the module, and may include gypsum board or an alternative interior facade material.

[0115] The walls of the module 950 may include openings 929 which may take the form of windows, doors, or louver panels that extend through the exterior and interior surfaces of the exterior, interior, or side walls.

[0116] 5 and 8 , in some forms, the freestanding module 950 is a balcony module 950a, which includes a balcony or other deck. The balcony module includes an interior wall 957 and an exterior wall 951 separated by a side wall 956. The exterior wall can include an upper wall member 911 and a lower barrier 918 positioned around a lower portion of the exterior wall and adjacent to a floor 953. In some forms, the lower barrier can be a railing extending between the side walls 956. The interior wall of the balcony module 950a can include an opening 929 in the form of a door or window.

[0117] 6 and 9, in some embodiments, the freestanding module 950 is an enclosed balcony module 950b. The enclosed balcony module 950b differs from the balcony module 950a primarily by the addition of a fixed window 929 that extends between the lower barrier 918 and the top wall member 911 that surrounds the balcony module. In the embodiment shown in Figures 6 and 9, the side wall 956 of the enclosed balcony can also include a fixed window 929 that extends between the floor 953 and the top wall member 911.

[0118] 7 and 10, in some embodiments, there is a freestanding module 950 that is substantially enclosed so as not to include a balcony. Freestanding module 950c differs primarily from balcony modules 950a and 950b in that it is enclosed by exterior and side walls and does not include interior walls. Module 950c opens on one side adjacent to the multi-story building to provide access to the module.

[0119] 7 and 10, further wall portions 952 extend from the outer wall towards the top member 911 which extends between the side walls 956. The further wall portions act to subdivide the module and can provide further lateral stability to the module.

[0120] The facade modules disclosed above may be formed from a monolithic panel construction or may be formed as a skeletal frame (typically having steel or metal load-bearing members and optionally infill members).

[0121] Changes and modifications can be made to the foregoing without departing from the spirit or scope of the disclosure.

[0122] In the following claims and the preceding description of the invention, unless the context requires otherwise by express language or necessary implication, the word "comprises" or variations such as "comprises" or "comprising" are used in their inclusive sense, i.e., they specify the presence of stated features but do not exclude the presence or addition of further features in various embodiments of the invention.
