Knockdown Rebuild Builder in Balmain
Here is the truth about knockdown rebuild in Balmain: it almost never happens. Heritage Conservation Areas cover virtually the whole peninsula, and Council will not let you demolish a Victorian terrace or sandstone workers' cottage that contributes to the streetscape. Blocks run 100 to 400m² and the housing dates from the 1850s to the 1920s, this is fabric the Inner West protects hard. Anyone promising you a clean demolition approval here has not read the LEP.
The exceptions are rare, a non-contributory post-war infill inside an HCA, or a dwelling already compromised beyond repair, and even then you are arguing the case with heritage consultants. Foreshore Building Line restrictions add another layer on anything near Mort Bay or Iron Cove. What most Balmain owners actually need is a rebuild behind a retained facade or a serious restoration-extension.
What I would check first on a Balmain block: whether the home is contributory to an HCA, any Foreshore Building Line near the water, and what the site can legally carry. Those decide it.
We build these fixed-price, licence HBL 487805C. Ask us to assess what your site can legally carry before you spend a cent on design.
Buildana manages the complete knockdown rebuild process in Balmain — 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.

Demolition almost never gets approved
Heritage Conservation Areas cover virtually the whole Balmain peninsula, and Council will not let you demolish a Victorian terrace or sandstone workers' cottage that contributes to the streetscape. The housing dates from the 1850s to the 1920s, fabric the Inner West protects hard.
Anyone promising a clean demolition approval here has not read the LEP. So the knockdown, not the rebuild, is what stops most projects.

How It Works
From First Call to Final Key
Free site inspection of your Balmain property. We check lot dimensions, Inner West Council's planning controls, existing home condition, and potential asbestos.
⏱KDR is the chance to get the design right — the new build doesn't have to mimic the original layout. We start from your block's strengths (orientation, slope, views) and your family's brief, then design the home the original lot always deserved.
⏱Licensed demolition of existing 1850s–1920s-era dwelling. Asbestos removal by certified contractors (if present).
⏱Your new home goes up on the cleared site. Engineered slab sized for Class M soil, frame, roof, fit-out, kitchen, bathrooms, flooring, painting, driveway, and landscaping.
⏱Handover pack: OC, structural certificates, BASIX, appliance manuals and warranties, paint colour schedule, maintenance plan, and the keys. Six-year structural warranty kicks in from OC date — keep the documentation safe for any future sale.
⏱Quality Promise
Balmain KDR projects run on one contract: demolition, asbestos clearance, approvals, construction, handover. One builder accountable.
