Home Extension Builder in Fairfield
Fairfield's 1950s–1980s-era homes are often compact by modern standards — three-bedroom houses on generous 450–700m² blocks with plenty of room to extend. Ground-floor extensions, second-storey additions, and rear living extensions are all popular in Fairfield. Buildana is based right here on The Horsley Drive and has completed numerous home extension projects across the LGA, navigating Fairfield City Council's setback, FSR, and height controls.
Buildana manages the complete home extension process in Fairfield — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.
