Light-gauge steel frame kits |
Panelized or component-based house kits |
Cold-formed galvanized steel framing, with separately specified sheathing, insulation, and exterior finishes. |
Small homes, villas, extensions, and low-rise residential projects. |
Confirm structural calculations, corrosion protection, insulation details, and that the kit is designed for the project’s local wind, snow, and seismic requirements. |
| 2 |
Modular building suppliers |
Volumetric modular units |
Three-dimensional modules assembled in a factory, commonly using steel or timber frames with wall, floor, and ceiling assemblies. |
Residential units, staff accommodation, hotels, and projects requiring rapid on-site assembly. |
Check transport dimensions, lifting points, module connections, utility interfaces, and what finishing work remains after delivery. |
| 3 |
Container-based building suppliers |
Container-style house kits |
Steel container-like frames or modified shipping-container structures, typically fitted with doors, windows, insulation, and interior panels. |
Temporary accommodation, site offices, cabins, and compact living spaces. |
Ask whether the product uses a new purpose-built frame or a reused container, and verify insulation, condensation control, corrosion protection, and local building-code suitability. |
| 4 |
Timber-frame kit suppliers |
Timber panel or frame kits |
Factory-cut structural timber members or wall panels, with roof and floor components specified according to the design. |
Cabins, cottages, low-rise homes, and recreational buildings. |
Review timber grading, moisture content, treatment requirements, connection details, fire performance, and protection against moisture and pests. |
| 5 |
Insulated sandwich-panel suppliers |
Panelized building kits |
Insulated panels commonly made with metal facings and a core such as EPS, polyurethane, or mineral wool. |
Small buildings, extensions, site facilities, and light commercial structures. |
Compare core material, panel thickness, fire-test documentation, thermal performance, joint details, and suitability for the intended occupancy. |
| 6 |
Rock-wool panel kit suppliers |
Fire-conscious insulated panel kits |
Metal-faced panels with a mineral-wool core, installed as part of a designed wall or roof assembly. |
Projects where fire performance and sound control are important considerations. |
Request test reports for the complete assembly, not just the core material, and check panel joints, fixings, and moisture-management details. |
| 7 |
Expandable modular-unit suppliers |
Fold-out or expandable container-style kits |
Transportable steel-framed units designed to open or expand on site, with factory-fitted or optional interior components. |
Temporary housing, emergency accommodation, and relocatable site facilities. |
Confirm deployment procedures, foundation needs, weather sealing, utility connections, and the transport configuration and weight. |
| 8 |
Prefabricated roof and wall system suppliers |
Hybrid panel-and-frame kits |
Engineered frames combined with factory-made wall, roof, or floor panels; components may come from different production lines. |
Custom homes and projects with non-standard layouts or locally sourced finishes. |
Ensure the drawings coordinate all components, identify who is responsible for engineering, and specify tolerances and connection hardware. |
| 9 |
Small-home and cabin kit suppliers |
Compact cabin or tiny-home kits |
Small-footprint frame or panel packages, often with optional windows, doors, roof coverings, and interior finishes. |
Garden cabins, holiday units, studios, and compact residential buildings. |
Check permitted use, minimum room and egress requirements, foundation design, insulation level, and which items are excluded from the kit. |
| 10 |
Turnkey prefab-home package suppliers |
Design-and-supply packages with varying completion levels |
A coordinated package that may include structural components, envelope materials, windows, doors, and selected interior systems. |
Residential projects seeking a broader supply scope from one contractor or supplier. |
Define the exact delivery scope, installation responsibilities, engineering approvals, warranties, logistics, and local permitting requirements in writing. |
