[0002] AN ADJUSTABLE STRUCTURAL SYSTEM WITH INTEGRATED STANDARDISED COMPONENT MODULES OF INDUSTRIALISED PRODUCTION AND WAREHOUSING DISTRIBUTION

[0003] TECHNICAL FIELD

[0004] The present invention relates to prefabricated building systems and methods for constructing residential structures using a standardised suite of steel components manufactured under a programmed schedule of operational steps which aims to improve upon the limitations of traditional concrete / brick, timber residential construction methodology, and modern light gauge steel modular systems. Specifically, the invention provides a steel-based structural framework consisting of ten precision-engineered components designed for mass production in a dedicated manufacturing facility, optimised transportation, and rapid on-site assembly. The system employs a predetermined sequence of manufacturing steps such as laser-guided cutting, and robotic welding which improve on the construction tolerances currently in the market. These components are designed for off-the-shelf availability, enabling streamlined production cycles, efficient warehousing, and direct delivery to building sites.

[0005] The invention’s “kit-of-parts” methodology allows builders to configure structures of varying dimensions, roof slopes, and disaster-resistance levels (e.g., bushfire or cyclonic wind regions) using standardised assemblies, eliminating custom fabrication delays and guarantees early weatherproofing for uninterrupted internal works. Components are engineered for compatibility with conventional construction equipment, enabling installation within days of site preparation via simple steel-steel bolted connection which eliminates the requirements to weld. The system facilitates industrialised production for bulk selling and warehousing distribution.

[0006] BACKGROUND OF THE INVENTION

[0007] Residential construction has traditionally relied on timber framing and on-site fabrication, processes inherently limited by the natural variability of wood, weather dependencies, and labor-intensive workflows. Timber, while widely used, suffers from dimensional inconsistencies due to warping, shrinkage, and susceptibility to moisture, often requiring extensive remedial works such as shimming, re-cutting, or retrofitting to achieve structural alignment. These adjustments consume a significant portion of labor hours and frequentlyresult in defects such as uneven walls, misaligned service conduits, and compromised weather sealing.

[0008] Traditional concrete and brick construction is hindered by prolonged project timelines due to sequential on-site workflows such as brick laying, formwork, and curing of concrete, labour-intensive craftsmanship requiring specialised trades and susceptibility to material waste from on-site adjustments. Quality control is compromised by variability in manual craftsmanship, risking structural inconsistencies. Weather disruptions delay curing and scheduling, and midconstruction design changes incur significant rework costs. Masonry systems demand periodic maintenance such as repointing while concrete constructions require costly reinforced concrete foundations. These factors collectively reduce scalability, cost-efficiency, and long-term viability in contemporary construction demands.

[0009] Modular construction emerged to address these inefficiencies by pre-fabricating components off-site. However, most modular systems employ rigid, non-reconfigurable designs that restrict architectural creativity to repetitive layouts. Fixed dimensions lead to material wastage during manufacturing, as unused portions of components are discarded, and limit adaptability to site-specific requirements. Additionally, existing prefabricated steel systems often rely on on-site welding or custom fabrication for non-standard designs, negating the time-saving benefits of prefabrication. Builders face further challenges from skilled labor shortages, particularly in specialised trades like welding.

[0010] Weather exposure compounds these challenges. Traditional construction timelines are vulnerable to delays from rain, high winds, or extreme temperatures, which halt concrete curing, delay roofing, or damage partially completed structures. Even modular systems, while reducing on-site time, often fail to achieve early weatherproofing, leaving internal fit-out trades exposed to delays.

[0011] The proposed kit-of-parts system addresses a significant gap in the market for building solutions by offering the following benefits:

[0012] - Flexibility and Scalability: This prefabricated system is both flexible and scalable, allowing for adjustments to accommodate various architectural designs and layouts by using the comer load-bearing component to set the dimensions of the building followed by the fitting of other components, including different floor heights, floor, roof and wall spans and roof angle.4

[0013] - Elimination of Material Variability: The system reduces alignment issues by utilising precision manufactured steel components, ensuring quality during construction.

[0014] - Reduced Dependency on Skilled Labor: With bolted connections and standardised assemblies, the system allows assembly by semi-skilled workers, minimising the need for specialised labor.

[0015] Accelerated Timelines: This system enables structural lock-up within days of site preparation, providing weatherproofing for the building envelope and allowing uninterrupted internal fit-out work.

[0016] - Minimised Waste: The use of prefabricated components reduces the amount off-cuts on site, thus minimising waste.

[0017] Assured Quality Control: The exposed bolted joints facilitate visual inspection, reducing the risk of loose fasteners and ensuring quality throughout the assembly process.

[0088] DETAIL DESCRIPTION OF EMBODIMENTS

[0089] The present invention discloses a prefabricated steel structural system for building construction, comprising ten precision-engineered, standardised components which exceed the dimensional accuracy of conventional timber-framed structures. The system integrates a kit-of-parts system optimised for automated mass production, logistics efficiency, and rapid on-site assembly. Components can be palletised into flat-pack modules optimised for ISO-container compatibility, with maximum widths of 2.4 meters to streamline global logistics. On-site assembly leverages a bolt-together sequencing methodology, wherein pre-drilled connection points and slotted channels enable rapid structural integration.

[0090] The present disclosure provides a detailed description of the structural and functional configurations of individual components, assemblies, and the overall building structure. In one embodiment, the kit-of-parts system is configured to form a foundation assembly, flooring assembly, a wall assembly, or a roofing assembly, depending on the desired architectural arrangement. In further embodiments, the system includes two or more interconnected building components that are combined to create a cohesive building assembly, with the flexibility to adapt to various design requirements and spatial configurations. The system enables both homogeneous and heterogeneous configurations to12

[0091] meet diverse architectural and environmental demands. Homogeneous configurations utilise uniform modules, such as solid wall panels, to expedite repetitive assembly in standardised layouts. Conversely, heterogeneous configurations integrate mixed modules — such as alternating solid wall units and apertured units with pre-engineered window or door openings — to accommodate bespoke architectural features. This kit of parts system allows for customization and reconfiguration to suit a wide range of architectural needs.

[0092] Foundation System Assembly

[0093] The foundation system is designed as a steel structural framework, providing a robust and adaptable base for building construction. It incorporates 200* 100x3mm thick rectangular hollow section tubes as primary framing members along with 100x50x3mm C-shaped channels, which are precision-engineered with 100mm long x 50mm wide slotted chamfered holes which serve as penetrations and allow concrete to flow into to ensure there are no voids and honeycombing of the completed composite concrete foundation slab. This innovative design eliminates the need for traditional formwork or strip footings, streamlining the construction process. Secondary framing is achieved using C-type light gauge steel joists , which are interconnected with right-angle bracing to ensure precise 90-degree alignment during assembly. The system also integrates level adjustment components to enable finetuning of the foundation's alignment, along with steel reinforcement mesh and distributed steel bars positioned below to enhance load distribution and structural stability.

[0094] The assembly process begins with site preparation, followed by the installation of the steel framing system atop deep foundation supports, such as screw piles or bored piles. Horizontal right-angle platform bracing and vertical level-adjustment components are used to level the ground and ensure accurate alignment during assembly. A waterproof membrane is placed on top of the compacted soil or ground. The steel components are connected using a simple bolting and Tek screw method, eliminating the need for on-site welding and significantly reducing construction time and costs. Once the steel frame platform is fully assembled, steel reinforcement mesh is installed on top, with additional distributed reinforcement bars positioned beneath. Concrete is then poured directly into the framework, filling the slotted chamfered holes to solidify the structure and ensure seamless integration of the steel and concrete elements.13

[0095] This foundation system offers several key advantages. By integrating the steel framework and concrete pour into a single step, it eliminates the need for traditional formwork and strip footings, simplifying the construction process. The slotted chamfered holes in the steel tubing allow for direct concrete pouring, enhancing structural integrity while maintaining efficiency. The use of C-joists, square hollow sections, and bolted connections ensures rapid, accurate assembly without the need for on-site welding, further reducing labor requirements and project timelines. Additionally, the system is compatible with various deep foundation solutions, including screw piles and bored piles, making it suitable for diverse soil conditions. Precision-engineered features such as right-angle bracing and three-dimensional leveling adjustments ensure accurate alignment and provide a stable working surface for subsequent construction stages.

[0096] This advanced framing steel structural foundation system represents a versatile and efficient solution for modern construction. It delivers a strong, level base that can be tailored to accommodate different architectural arrangements, while minimising material waste as there are no off-cuts on site, labour costs, and environmental impact. Its adaptability, precision, and ease of assembly make it an ideal choice for projects requiring both speed and structural reliability.

[0097] Wall Components Assembly

[0098] The wall assembly system utilises a rectilinear grid framework composed of individualised panel wall components, which are arranged in a perpendicular configuration to ensure uniform load distribution and lateral stability. Each panel incorporates longitudinal and transverse members that are discretely fabricated and assembled, rather than relying on continuous members. These components are designed to accommodate architectural features such as window sills or headers through precise segmentation, ensuring structural integrity while allowing for functional and aesthetic flexibility. Openings, apertures, or voids are strategically integrated into the panels, with their perimeters defined by reinforced members to maintain load-bearing capacity. The comer wall load-bearing component plays a critical role in securing all corners of the building, providing both lateral and vertical support to stabilise the structure and ensure alignment. This kit-of-parts approach enables seamless integration of windows, doors, utilities, or decorative elements, offering a highly adaptable and precise solution tailored to diverse design requirements.Corner Wall Load-Bearing Component

[0099] The Comer Wall Load-Bearing Component is a critical structural element designed to secure the comers of the building while providing both lateral and vertical support. This component ensures the stability and alignment of the structure, with a standard dimension of 600mm wide and 2700mm high, featuring integrated diagonal bracing for enhanced rigidity. The height can be customised to accommodate specific project requirements. Fabricated from 100* 100x3mm thick square hollow sections as vertical members, 100x 100x3mm thick C-shaped channels (laid flat) as top and bottom horizontal members, and 100x50x3mm thick rectangular hollow sections as diagonal bracing members, this component is engineered for durability and precision.

[0100] Prefabricated and shop-welded to ensure consistent quality, the component is connected to the top plate, bottom plate, or foundation system using bolts. The ring beam module is installed, connecting all comer wall load-bearing components, securing the dimensions of the building. Both vertical and diagonal members are pre-drilled with penetrations to facilitate the seamless integration of service conduits, such as plumbing and electrical wiring, during installation. A key advantage of this component lies in its ability to define and stabilise the overall dimensions of the structure, offering flexibility and scalability to meet varying design needs.

[0101] Rectangular Wall Load-Bearing Component

[0102] The Rectangular Wall Load-Bearing Component serves as a primary vertical support element within the wall assembly, ensuring structural integrity across the building envelope. With a standard dimension of 600mm wide and 2700mm high, the component’s height can be adjusted to align with customer specifications. Constructed using 100x 100x3mm thick square hollow sections as vertical members and 100x 100x3mm thick C-shaped channels (laid flat) as top and bottom horizontal members, this component is bolted to the top plates, bottom plates, or foundation frames.

[0103] For additional lateral stability, diagonal bracing similar to that used in the comer wall loadbearing component can be incorporated when required. Prefabricated and shop-welded, the component ensures precise alignment and ease of installation on-site. Vertical members are pre-drilled to accommodate service conduits, including pipes and electrical wiring, ensuring compatibility with building services. These components are installed at standardised intervals15

[0104] of approximately 1400mm , following the placement of corner wall load -bearing components and top plates, to ensure uniform load distribution and structural continuity.

[0105] Window and Door Load-Bearing Component

[0106] The Window and Door Load-Bearing Component is specifically engineered to provide vertical support while accommodating openings for windows and doors. This component features a standard height of 2700mm, with a width that can be customised based on the size of the door or window. The height is also adjustable to meet client-specific requirements. Constructed using 100* 100><3mm thick square hollow sections as vertical members (serving as door and window jambs), 100x 100x3mm thick square hollow sections as horizontal members for window heads and sills, and 100x 100x3mm thick C-shaped channels (laid flat) as top and bottom horizontal members, this component is bolted to the top plates, bottom plates, or foundation frames. Vertical intermediate members are installed to support the sill member, depending on the width of the opening.

[0107] Prefabricated and shop-welded for precision, the component ensures accurate alignment during installation. Vertical members are pre-drilled to allow for the integration of service conduits, such as pipes and electrical wiring. In regions subject to high wind loads, such as cyclonic areas, the vertical members can be upgraded to 200x 100x3mm thick rectangular hollow sections to enhance structural resilience. These components are installed in their designated locations within the wall assembly after the comer wall load-bearing components and top plates have been secured, ensuring seamless integration into the overall structural framework.

[0108] The installation process begins with the secure attachment of the Comer Wall Load-Bearing Components to the primary steel frames using hold-down bolts. These components form the structural anchor points for the building’s corners, establishing the foundation for subsequent assembly steps. Following this, the top plates are installed, connecting all comer wall components to ensure proper alignment and continuity across the structure.

[0109] Once the top plates are in place, the Rectangular Wall Load-Bearing Components and Window and Door Load-Bearing Components are installed in their respective locations. These components are positioned at standardised intervals of approximately 1400mm, ensuring uniform load distribution and structural stability.16

[0110] Once the load-bearing components and first floor joists are installed, the internal formed ceramic panels are mechanically fixed along with the use of a structural adhesive to the wall modules. Once the internal rough-in is complete, the external formed ceramic panels are then similarly fixed to the wall modules.

[0111] This wall assembly system combines prefabrication, kit-of-parts design, and precise engineering to deliver a solution that is both versatile and reliable. By integrating a rectilinear grid structure with customisable openings and apertures, the system meets the demands of modern construction projects while ensuring compliance with structural and performance standards.

[0112] Flooring Components Assembly

[0113] The flooring system is engineered to deliver a robust and adaptable framework for supporting first-floor structures, ensuring compatibility with varying load requirements and architectural configurations. At its core, the system features First Floor Joists, which are precision-fabricated from 400* 100x3mm thick C-shaped steel. These joists serve as the primary loadbearing elements of the floor assembly and are pre-drilled with penetrations to facilitate the seamless integration of service conduits, mechanical ducts, and other building services.

[0114] Installed on the top surface of the top plates using Tek screws, the joists are spaced at a standard center-to-center interval of 700mm, though this spacing can be adjusted — either reduced to 450mm or increased to 750mm — to accommodate specific design floor loads. Available in standard lengths of 6 meters, 9 meters, and 12 meters, the joists can also be custom-cut to suit unique floor plans. For areas subjected to higher concentrated loads, such as heavy fixtures or equipment, double joists — a reinforcement method achieved by pairing two joists together — can be implemented to enhance load-bearing capacity. Over-length joists are available upon special order to meet specific project requirements. Furthermore, it directly fixes the ceiling — a 8mm thick aluminium honeycomb panel, eliminating the use of a drop-ceiling method.

[0115] Supporting the floor joists are the Ring Beam Modules, which consist of Top and Bottom Plates constructed from 100x 100x3mm thick square hollow sections. The top plate is supported by the underlying load-bearing components, while the bottom plate is securely seated on the floor joists. These plates play a pivotal role in stabilising the overall structure, providing lateral restraints that mitigate instability in both walls and floor joists. For17

[0116] applications requiring cantilevered features, such as roofs or balconies, the section size of the top and bottom plates can be upgraded to 200* 100><3mm thick rectangular hollow sections, ensuring enhanced load-bearing capacity and structural rigidity.

[0117] The installation process begins with the positioning of the First Floor Joists on the top surface of the top plates, secured with Tek screws at the specified spacing intervals. Adjustments to spacing are made based on the anticipated floor loads, ensuring optimal performance and safety. Following this, the Bottom Plates are installed on top of the floor joists, with careful attention to alignment and connection to ensure stability and support for subsequent construction stages. For first-floor walls, the installation process mirrors the steps outlined for the wall assembly system, including the placement of corner wall load-bearing components, top plates, and other wall elements.

[0118] Structural waterproofing in wet areas (e.g., balconies) is achieved by varying the material thicknesses of the internal, wet and exterior floors which creates a setdown. The thickness of internal floors and wet areas such as bathrooms and balconies are 50mm, while other internal floors are 75mm. A 1mm thick Z-shaped metal strip covers the flooring to ensure waterproofing. This protects steps against water ingress in a low risk manner as it is not over reliant on sealants which have the possibility of failure over time.

[0119] This flooring system seamlessly integrates with the wall assembly system, offering a flexible and scalable solution for first-floor construction which can be flexibly adjusted to varying plan dimensions.

[0120] Roof Components Assembly

[0121] The ceiling and roof system is meticulously engineered to provide a robust, adaptable framework that supports ceiling panels, roofing materials, and external finishes while accommodating diverse architectural and functional requirements. At the core of this system is the ceiling joist, constructed from 100x 100x3mm thick C-shaped steel, which serves as the primary structural element for supporting ceiling panels. These joists are installed on the top plates using Tek screws at a standard center-to-center spacing of 700mm, ensuring uniform load distribution and structural stability.

[0122] Enclosing the roof structure is the fascia beam, also called 3-in-l waterproof tube beam, fabricated from a 200x 100x3mm rectangular hollow section and supported by the top plates.The fascia beam fulfills multiple critical functions, acting as the termination point for the external formed ceramic 2700x600mm wall panels while providing essential support for the roof gutter system. Additionally, it plays a pivotal role in the innovative roof waterproofing system, enhancing the durability and weather resistance of the overall structure.

[0123] The roof rafters, constructed from 100x 100x3mm square hollow sections, are installed at a standard spacing of 800mm and connected to the fascia beam, effectively functioning as roof trusses. These rafters are designed with an adjustable slope ranging from 5 to 11 degrees, allowing for customisation to accommodate specific roof design requirements. Installed using Tek screws, the rafters provide a stable framework for attaching roofing materials, including sarking and insulation, ensuring thermal efficiency and effective weatherproofing.

[0124] The installation process begins with the secure attachment of the ceiling joists to the top plates, ensuring precise alignment and consistent spacing. Following this, the perimeter fascia beam is installed using specialised connectors, securing its position as both a structural and aesthetic element. The ceiling joists are fixed to the fascia beam with 70x100x1.5mm steel brackets. In addition, 300x 100x 1 ,5mm steel brackets are fixed to the fascia beam to connect the roof rafters. They are positioned and fixed in place with Tek screws, maintaining the specified spacing and slope. Roofing materials, including sarking and insulation, are applied to the rafter framework to complete the roof assembly.

[0125] Once the structural framework is finalised, the system is completed by installing internal wall panels, external formed ceramic panels, and floor panels. This seamless integration of the ceiling, roof, and wall systems ensures a cohesive solution tailored to modem construction demands.

[0126] Formed Ceramic Panel System

[0127] The kit incorporates non-load bearing formed ceramic panels as integral components for load-bearing walls, internal walls, and floor elements, offering a lightweight, durable, and multifunctional solution for modern construction. These formed ceramic panels are engineered to be non-combustible, waterproof, and thermally insulating, making them highly suitable for residential applications. Available in rigid board formats with thicknesses of 50mm, 75mm, and 100mm, the panels are designed to achieve a standardised finished wall thickness of 300mm when installed on load-bearing components. The panels include non-19

[0128] combustibility, waterproofing, and thermal insulation, guaranteeing performance and safety across diverse environmental conditions.

[0129] For ease of maintenance and redecoration, the formed ceramic panels are fixed to loadbearing components using mechanical fasteners, enabling tool-less removal and reinstallation without compromising structural integrity. This feature enhances the adaptability of the system, allowing for efficient updates or repairs over the building’s lifecycle.

[0130] In internal wall applications, the formed ceramic panels are fixed vertically between floor joists and ceiling plates, forming wall components with standard dimensions of 600mm wide by 2700mm high . These panels are secured to the bottom of the floor and the top of the ceiling or floor joists, providing a seamless and rigid internal wall finish. For flooring applications, the formed ceramic panels are installed directly onto floor joists, creating a robust, waterproof, and insulating surface that is well-suited for residential use.

[0131] The standard panel size is 600mm by 1400mm, ensuring compatibility with the grid framework of the wall and floor assembly systems. When used as an external or internal skin, the formed ceramic panels are fixed to the load-bearing components, serving as a durable and aesthetically pleasing wall finish. Their versatility, combined with their compliance with key Australian Standards, makes these formed ceramic panels a reliable and high-performance solution for contemporary building projects.

[0132] CONSTRUCTION METHODOLOGY PROCESS

[0133] 1. Site Preparation and Foundation

[0134] Involves the levelling of the ground, compacting of the soil and marking layout lines. Screw piles, with diamond-shaped elongated holes, are installed according to marked positions, ensuring all pile heads are levelled within a + / - 10mm tolerance.

[0135] The foundation frame assembly begins with mounting 200* 100mm rectangular hollow section tubes into screw piles, with horizontal right-angle platform bracing brackets and secured with screw locks to align tubes.

[0136] Distributed reinforcement is placed through the penetrations of the steel webs, followed by steel top mesh for cracking control, concrete is then poured and finished with surface grinding.20

[0137] Ground Floor Structural Wall Installation

[0138] Begins with the installation of all 600x600mm comer load-bearing components, bolted to the foundation, followed by the installation of the ring beam module — a 100x 100mm top plate which secures all corner-load bearing components, ensuring proper alignment and continuity across the structure. Following this, the rectangular wall load-bearing components and window and door load-bearing components are installed in their respective locations. Once the structural components are installed and fixed, the interior formed ceramic panels are installed, followed by the exterior formed ceramic panels.

[0139] First Floor Joist Assembly

[0140] Fixes 400x100mm C-beams, with pre-drilled penetrations for service conduits, to the previously installed top plates, spaced at 700mm. Following this, secondary

[0141] 100x 100mm top plates are installed, bolted to the C-beams. Figure 9 illustrates this relationship between the floor joists and ring beam module.

[0142] First Floor Structural Wall Installation

[0143] Follows the same construction methodology to the ground floor structural wall installation, whereby comer load-bearing components are first installed, followed by the top plate, then the wall load-bearing components and window and door loadbearing components. Similarly, once the structural components are installed and fixed, the interior formed ceramic panels are installed, followed by the exterior formed ceramic panels.

[0144] Ceiling Joist, Fascia Beam and Gutter Installation

[0145] Involves a 100x 100mm C-shaped ceiling joist bolted to the top plate and fixed to the 200x100mm rectangular hollow section fascia beam, via a 70xl00x 1.5mm steel bracket. The eave gutter is then fixed to the fascia beam.

[0146] Roof Rafter Installation

[0147] Involves the fixing of 100x 100x3mm square hollow sections, spaced at 800mm, to the fascia beam (3-in-l waterproof tube beam integrated with eave fascia gutter) via a 300xl00x 1.5mm steel bracket, with an adjustable slope ranging from 5 to 11 degrees.A 300mm wide 1.5mm thick adjustable ridge cap secures the roof rafters, followed by the installation of sarking, insulation and metal roof sheeting.

[0148] INNOVATION SUMMARY

[0149] The kit-of-parts system introduces a transformative approach to building construction, combining precision-engineered steel components with a design philosophy inspired by traditional timber framing. The system comprises ten standardised modules, enabling mass storage, rapid assembly, and architectural / structural reconfigurability for single-story to duplex structures. Components utilise bolted connections to eliminate on-site welding, reducing labor and fast installation which results in reduced time to achieve a “weather sealed” system which also allows internal and external trades to work simultaneously. This innovation bridges traditional craftsmanship with modern efficiency, offering a scalable, sustainable solution for building construction. Components are flat-packed into ISO-container-compatible modules (max 2.4m width), streamlining global logistics. The system’s ten standardised modules enable rapid on-site assembly, reducing lead times compared to conventional methods.

[0150] The wall system assembly sequence is innovative compared with conventional timber framing, light gauge steel framing and modular structures. It allows small numbers of labourers on site. The assembly sequence of the walls starts from corner components at the corners of the building with top plates to set out the footprint of structures, following infilled rectangular and window / door modules. This innovative wall assembly shortens installation time compared to traditional framing methodology. It also reduces site risks, waste and rubbish.

[0151] The foundation system replaces conventional formwork and strip footings with rectangular hollow sections (200* 100><3mm RHS) and C-shaped steel joists (100x50x3mm C shaped channel) and slotted chamfered holes on members, enabling direct concrete pouring through the holes. This framework integrates steel reinforcement mesh and level-adjustment components for alignment with deep foundation systems (e.g., screw piles, bored piles), streamlining site preparation. Structural waterproofing in wet areas (e.g., balconies) is achieved by varying the material thicknesses of the internal, wet and exterior floors which creates a setdown. The thickness of internal floors and wet areas such as bathrooms and balconies are 50mm, while other internal floors are 75mm. A 1mm thick Z-shaped metal strip22

[0152] covers the flooring to ensure waterproofing. This protects steps against water ingress in a low risk manner as it is not over reliant on sealants which have the possibility of failure over time.

[0153] The roof system employs rectangular hollow sections (200* 100x3mm RHS) as perimeter beams to secure gutters, preventing water ponding and overflow. Adjustable rafters (100x 100x3mm SHS, 5°-ll° slopes) ensure compatibility with diverse architectural styles.

[0154] The open-plan structure eliminates internal load-bearing walls, relying solely on external walls for support, with long span C-shaped floor joist components. This design allows unrestricted layouts for rooms, kitchens, and bathrooms. Prefabricated wall components (600x2700mm) integrate formed ceramic panels (non-combustible, waterproof and weather-resistant) and a central 100mm steel tube, matching the width of standard brick veneer walls. The formed ceramic panels act as waterproof barriers, with 100mm wide cavity between external and internal panels, eliminating sarking and enabling rapid installation with structural adhesives and screw fixings.

[0155] Aluminium windows and doors are mounted on 140mm-wide sub-frames using structural waterproofing techniques, ensuring compliance with wind loads. Pre-drilled penetrations in steel joists and walls enable seamless service conduit integration.
