As Kiwi homes evolve and family needs change, extending or altering your home is often the best way to create additional space without moving. With trends in NZ showing strong demand for flexible, multi‑functional living areas, families are looking to enlarge living rooms, add bedrooms, create home offices, or optimise older layouts
