A knockdown rebuild in Glenhaven is a premium semi-rural project — 1970s to 2000s brick on substantial 1,500 to 4,000m² R2 lots, with established gardens, top schools and a leafy character that commands a real premium. The aging 1970s-80s stock on blocks this size is prime rebuild territory.
The block sizes give a rebuild extraordinary design freedom — a substantial single-level or a grand two-storey with real grounds. The shale-sandstone interface means the slab is designed off a real geotech, and the bushfire-adjacent edges carry a BAL rating worth checking.
The older stock can carry asbestos, so a licensed strip-out leads the demolition where needed.
We rebuild fixed-price, licence HBL 487805C. Get our feasibility before you commit.
Buildana manages the complete knockdown rebuild process in Glenhaven — 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.

Extraordinary blocks, aging stock
Glenhaven's 1,500 to 4,000m² lots are among the most generous R2 blocks in the Hills, and the aging 1970s-80s brick on them is prime rebuild territory. A knockdown delivers a substantial home with real grounds — the kind of design freedom suburban blocks never offer.
The leafy, semi-rural character and top schools keep the premium genuine.
Interface ground and bushfire edges
The shale-sandstone interface means the slab is designed off a real geotech — shale in the core, sandstone toward the rural edges. The bushfire-adjacent edges carry a BAL rating worth checking, which I do upfront.
The older stock can carry asbestos, so a licensed strip-out leads the demolition where needed.
