What This Service Involves
Home Extensions & Additions covers the coordinated activities needed to move from an initial brief to clearly described site works, inspections and handover. The principal work areas include structural and space feasibility, extensions, lofts and additional floors, and matching existing roof and façade. The appropriate sequence, materials, engineering input and contract responsibilities depend on the location, drawings, site conditions and the intended use of the building. A residential project must balance structural reliability, everyday comfort, natural light, ventilation, access and future maintenance. The condition of the land or existing building should be confirmed before technical decisions are made.
