Duplex Architect Northern Beaches, Dual Occupancy Design & Approvals

Northern Beaches planning notes for dual occupancy

• Steep, bushland and foreshore blocks are the norm, slope, BAL bushfire assessment and tree/vegetation controls frequently push projects to a DA.
• The Northern Beaches was formed from the former Manly, Warringah and Pittwater councils, so legacy LEP/DCP provisions can vary across the LGA.
• Design that steps with the land and retains canopy is far better received than a bulky, cut-and-fill approach.

On the Northern Beaches we assess slope, bushfire and vegetation together up front, these blocks reward difficult-site experience more than anywhere in Sydney. We confirm the legacy LEP, BAL and foreshore overlays before choosing a DA strategy that steps with the land rather than fighting it.
