A knockdown rebuild in Lavender Bay costs $450,000–$1,200,000+. Standard single-storey from $450K, two-storey from $650K. Buildana manages demolition, North Sydney Council approvals, and construction under one fixed-price contract.
Lavender Bay Knockdown Rebuilds
Knockdown rebuild in Lavender Bay needs a genuinely honest framing, because this tiny harbourside enclave looking straight at the Harbour Bridge is Federation cottages, sandstone terraces and apartments on very tight 200 to 450m² blocks, with Heritage Conservation Areas covering most streets. A standard knockdown is rarely the path here.
On a heritage cottage or terrace, the right move is almost always a sympathetic restoration and careful renovation that keeps the character, not a demolition. Council scrutiny is heavy given the setting and the views, and I will tell you honestly what your block actually allows.
The ground is sandstone-dominant with substantial harbour fall, so any approved works involve engineered foundations and retaining, priced from a real geotech. The old stock can carry asbestos and lead paint, so a licensed strip-out leads any demolition.
We build fixed-price, licence HBL 487805C. Get our honest feasibility — what is actually possible on your block — before you commit.
Buildana manages the complete knockdown rebuild process in Lavender 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 heritage enclave, handled honestly
Lavender Bay is a small harbourside enclave between McMahons Point and Milsons Point, looking directly at the Harbour Bridge and Opera House, famous for Wendy Whiteley's Secret Garden. Federation cottages, sandstone terraces and apartments sit on very tight 200 to 450m² blocks, with Heritage Conservation Areas covering most streets.
A standard knockdown is rarely the path here. On a heritage cottage or terrace, a sympathetic restoration that keeps the character is almost always the right move, and I will tell you honestly what your block allows.
Sandstone, fall and old stock
The ground is sandstone-dominant with substantial harbour fall, so any approved works involve engineered foundations and retaining, priced from a real geotech. On tight blocks with this setting, that ground work matters.
The old stock can carry asbestos and lead paint, so a licensed strip-out leads any demolition.

How It Works
From First Call to Final Key
We assess your Lavender Bay block — lot size (typical 200–450m²), R3 Medium zoning, setbacks, FSR, and existing dwelling condition. Asbestos survey included. You'll know feasibility and budget before committing.
⏱Complete design package: floor plans, elevations, 3D renders, structural engineering, geotech, BASIX, stormwater, and all documentation North Sydney Council requires. Approval managed start to finish.
⏱Pre-demolition: dilapidation report on adjoining properties (protects you against unfounded damage claims), service disconnections, asbestos clearance, neighbour notification. Then 1–2 weeks of physical demolition with material sorted at site for recycling where possible.
⏱Fixed-price construction: engineered slab, frame, lock-up, fit-out, external works. 8–12 months depending on size. Weekly progress reports with photos and milestone tracking.
⏱Same address, completely different home. Permanent gas, water, electrical, NBN reconnected and tested. Council waste collection re-registered. Mailbox reinstalled. Move-in ready, not move-in plus 100 small jobs.
⏱Quality Promise
Lavender Bay knockdown rebuild done cleanly: licensed demolition, compliant slab, new home built to NCC 2025. Fixed-price contract.
