Prefab house modules constitute the fundamental building blocks of volumetric modular construction, designed as self-contained structural units that combine to form complete dwellings. Each module is constructed as an independent load-bearing unit with full-height walls, floor, and ceiling assemblies engineered to withstand transportation and lifting stresses. Standard module widths typically range from 8 to 16 feet to comply with road transportation regulations, with lengths varying according to design requirements. The modules feature pre-installed exterior cladding, windows, and roofing materials completed under factory conditions. Interior spaces within modules can be designed as complete rooms or open areas that connect with adjacent modules. Structural connections between modules employ heavy-duty steel plates with moment-resisting connections that create unified structural performance. Service cores containing bathrooms or kitchens are often completed as entire modules with all plumbing fixtures tested prior to shipment. The modules incorporate built-in conduits and chases for electrical, data, and HVAC distribution systems with accessible connection points. Fire-rated assemblies are implemented at module junctions to maintain continuous compartmentalization. Acoustic separation between modules is achieved through resilient channels and sound-absorbing insulation materials. The modular system allows for various architectural expressions through different module arrangements and exterior finish combinations.
