A knockdown rebuild in Belrose is a bushland-edge Beaches project — 1970s to 1990s brick and contemporary on 600 to 1,200m² blocks backing Garigal National Park. The generous blocks and aging stock suit a substantial rebuild, with bushfire the defining design factor.
BAL-19 to Flame Zone applies on most lots, so the RFS Bushfire Protection Assessment is standard and the design meets its rating — that shapes materials, glazing, screening and cost. The sandstone means deep rock excavation of $50,000 to $150,000 is typical, priced from a geotech bore.
The older homes can carry asbestos, so a licensed strip-out leads the demolition.
We rebuild fixed-price, licence HBL 487805C. Get our feasibility, with the bushfire and rock costed, before you commit.
Buildana manages the complete knockdown rebuild process in Belrose — from site assessment and architectural design through to DA or CDC approval, demolition management, and fixed-price construction to handover. One builder, one contract, one new home.

Bushfire is the defining factor
Belrose backs Garigal National Park, so BAL-19 to Flame Zone ratings apply on most lots and the RFS Bushfire Protection Assessment is standard. The design meets its rating — materials, glazing, screening — and that is designed in from the start, not retrofitted.
On 600 to 1,200m² blocks, the generous space gives the bushfire-compliant design room to work.
Deep rock, priced from the bore
The sandstone means deep rock excavation of $50,000 to $150,000 is typical, priced from a real geotech bore so it is in the fixed price.
The older homes can carry asbestos, so a licensed strip-out leads the demolition.
