Can I build a granny flat on the Collaroy Plateau?

Yes, secondary dwellings are permitted on the Plateau. Under 2026 NSW rules, these can often be approved via CDC if the lot is 450sqm+ and meets the required setbacks. We design these to maximize views while meeting strict 7-star BASIX standards.

What are the restrictions for building on the Collaroy beachfront?

Properties in the Coastal Hazard Zone must comply with specific structural engineering and setback rules to account for wave impact and erosion. We provide the technical architectural drafting required to meet Northern Beaches Council's coastal management plans.

Do I need a BIC for a deck built without approval in Collaroy?

Yes. To legalise an unapproved structure, you need a Building Information Certificate (BIC). We provide the 'as-built' architectural plans and NCC compliance checks necessary for a successful application to Council.
