Homeowners can also choose between renovation-ready or fully-finished spaces. For example, the renovation-ready attic, constructed with glue-lam beams and structural insulated roof panels, is a dramatic cathedral-ceiling space, unimpeded by truss diagonals. Its floor is structurally designed for habitation and the space requires only minor finishing by the homeowner. Modularity adapts readily to factory construction, where greater efficiencies of material use, waste management, recycling and environmental controls can be realised.
