A knockdown rebuild in Neutral 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.
Neutral Bay Knockdown Rebuilds
A knockdown rebuild in Neutral Bay depends on what you hold, because this dense lower North Shore village around Military Road is a mix of apartments, townhouses and pockets of Federation and inter-war detached on 300 to 550m² blocks. Where you own one of the detached homes, a rebuild can work well.
Heritage Conservation Areas cover several streets including Hayes Street and Wycombe Road, so heritage is the first thing to check — a listed block goes down the DA path with a sympathetic design. On the R3 land, a dual-occupancy can be worth costing where a block clears the 500m² minimum.
The ground is Class M sandstone on the ridges, grading Class H to E on the harbour fall, so the slab is designed off a real geotech. The older 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 before you commit.
Buildana manages the complete knockdown rebuild process in Neutral 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.

Detached pockets in a dense village
Neutral Bay is a dense lower North Shore village around Military Road — apartments, townhouses and pockets of Federation and inter-war detached homes on 300 to 550m² blocks. Where you hold one of those detached homes, a rebuild can work well in a premium, walkable location close to the North Sydney CBD.
It is a lifestyle suburb where a smart rebuild on a compact block delivers real value.
Heritage, yield and harbour-fall soil
Heritage Conservation Areas cover several streets including Hayes Street and Wycombe Road, so a heritage block goes down the DA path. On the R3 land, a dual-occupancy can be worth costing where a block clears the 500m² minimum, so I run both where relevant.
The Class M sandstone ridge grades Class H to E on the harbour fall, so the slab is designed off a real geotech. The older stock can carry asbestos and lead paint, so a licensed strip-out leads the demolition.
