The home
Two WS modules stacked into a compact two-storey home. The ground floor holds dining, kitchen and living with glazed doors to the garden; upstairs, two bedrooms share a bathroom core and open onto a full-width balcony. The stair and services are aligned in the factory so the modules connect on site in hours.
What is built in the factory
- Steel frame – galvanised Q355 frame engineered for strength, precision and durability, with corner posts for lifting and stacking.
- Wet core – factory-built bathroom pod for quality and consistency.
- MEP rough-in – services pre-installed for fast connection on site.
- External envelope – high-performance thermal and weather protection.
- Interior fit-out – finishes designed for comfort and function.
- Dispatch ready – inspected, wrapped and ready for safe transport.
Every WS model shares the same module system – frame, floor, walls, roof, wet core and services – so specifications, approvals and spare parts stay consistent across a project.
Variants
Choose WS-ML-01 Base for standard residential or accommodation use, WS-ML-02 Fire-rated where enhanced fire performance is required, or a project-custom build-up – see the variant table on the module system page.

Perguntas frequentes
How long does production take?
Typically 4–6 weeks of factory production per batch after design approval, while foundations and site works proceed in parallel.
How much is finished in the factory?
Up to about 91 % of the work – frame, envelope, wet core, services and finishes. On site the modules are set on footings and connected to services.
Can the layout or finishes be changed?
Yes – finishes, fixtures, window positions and the build-up can be tailored as a project-custom variant.
How are the two storeys connected?
The upper module is bolted to the lower one at the corner posts; stair, services and weather seals are prepared in the factory.
