Short answer

On the Northern Beaches, owners usually compare local builders such as Beaches Group, Peninsula Homes, IMSU and Wattle Court with builders working across the North Shore and Beaches, such as Hall & Hart and Icon Homes, and design-range builders such as G.J. Gardner Homes and Montgomery Homes. Each states on its own website that it builds on the Northern Beaches. AUD Build (this is us) has completed 3 homes here through its group’s building companies since September 2024, in Frenchs Forest and Belrose. Before choosing, check your lot: Northern Beaches Council averaged 78 days to assess a DA in September 2026, the council’s bush fire prone land map covers the area, and in the Warringah LEP 2011 area dual occupancies have applied only to sites over 800 m² since 31 October 2025.

HeritageChanges to a heritage-listed property need a development application; complying development demolition is limited in heritage conservation areas[7] [8]

How to choose

  2. If the lot is bush fire prone, ask each builder how the BAL rating changes the design and the price.
  3. For a duplex, check the Warringah 800 m² rule or, near a listed centre, the state 450 m² and 12 m standard.
  4. Ask every builder to quote on the same drawings and compare inclusions line by line with the inclusions checklist.
  5. Check the licence on Verify NSW and the HBC certificate before you pay a deposit.
