A knockdown rebuild in Rose Bay costs $450,000–$1,200,000+. Standard single-storey from $450K, two-storey from $650K. Buildana manages demolition, Woollahra Municipal Council approvals, and construction under one fixed-price contract.
Rose Bay Knockdown Rebuilds
A knockdown rebuild in Rose Bay is a premium harbour-beach project — New South Head Road spine, a harbour beach and ferry wharf, Federation mansions and harbourside apartments on 300 to 1,500m² blocks with substantial fall to the harbour. On a detached home with harbour fall, a rebuild designs around a genuine harbour outlook.
Heritage Conservation Areas cover most streets, so a rebuild generally goes down the DA path with a sympathetic design, and on a heritage mansion a restoration is worth weighing. The substantial harbour fall means suspended slabs, retaining and rock excavation, all priced from a real geotech.
The pre-war stock can carry asbestos and lead paint, so a licensed strip-out leads the demolition. Where you hold an apartment, a knockdown does not apply.
We rebuild fixed-price, licence HBL 487805C. Get our feasibility — rebuild or restore — before you commit.
Buildana manages the complete knockdown rebuild process in Rose Bay — 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.

A premium harbour-beach village
Rose Bay is a harbour beach village — the New South Head Road spine, a harbour beach and ferry wharf, the seaplane base, and Federation mansions on 300 to 1,500m² blocks. A rebuild on a fall block designs a substantial home around a direct harbour outlook.
It is a sought-after harbourside address where a quality rebuild holds real value.
Heritage, harbour fall and rock
