A knockdown rebuild in Clifton Gardens costs $450,000–$1,200,000+. Standard single-storey from $450K, two-storey from $650K. Buildana manages demolition, Mosman Council approvals, and construction under one fixed-price contract.
Clifton Gardens Knockdown Rebuilds
A knockdown rebuild in Clifton Gardens is a premium harbour-fall project on Chowder Bay and Taylors Bay, with Sydney Harbour National Park frontage — Federation mansions, inter-war heritage and contemporary harbourside builds on 600 to 1,500m² blocks. This is about as premium as harbour building gets, and the ground reflects it.
Deep rock excavation is typical here, and combined with the substantial harbour fall, a rebuild needs suspended slabs and substantial retaining. I get a real geotech so the deep rock, fall and retaining are all costed properly, because on a Clifton Gardens block this is the bulk of the substructure budget.
Heritage Conservation Areas cover virtually all 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 pre-war stock can carry asbestos and lead paint, so a licensed strip-out leads the demolition.
We rebuild fixed-price, licence HBL 487805C. Get our feasibility, with the deep rock and fall costed, before you commit.
Buildana manages the complete knockdown rebuild process in Clifton Gardens — 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.

Ultra-premium harbour frontage
Clifton Gardens is the harbour-fall enclave on Chowder Bay and Taylors Bay, with Sydney Harbour National Park frontage — Federation mansions and contemporary harbourside builds on 600 to 1,500m² blocks. It is about as premium as harbour building gets, and a rebuild here designs a substantial home around direct harbour access and outlook.
It is an address where the build quality has to match the setting.

How It Works
From First Call to Final Key
Site visit covers everything that affects the build cost: vehicle access for trucks and crane, services (sewer depth, water connection, electrical service rating), soil exposure for borehole, neighbouring construction, and any obvious heritage or tree constraints. Real numbers, not estimates.
⏱Architectural design for your replacement home, structural engineering for Class M soil, BASIX certification, and all approval documentation. Lodged as CDC (10–15 days) or DA (40–90 days) depending on design.
⏱Demolition runs 5–10 working days for a standard Clifton Gardens cottage — longer if asbestos volume is significant or the structure includes a brick chimney or solid-block walls. Asbestos work happens first under a controlled removal program before mechanical demo starts.
⏱New home built from engineered slab (Class M soil) to keys — fixed-price, milestone-based progress payments. Your project manager provides weekly updates.
⏱Walk through your finished home on your original Clifton Gardens block. OC issued, all services live, 6-year structural warranty, appliance manuals, and maintenance schedule.
⏱Quality Promise
Every Buildana knockdown rebuild in Clifton Gardens is delivered under a fixed-price contract — site assessment through to defect-free handover.
