A knockdown rebuild in Botany is workable with the right checks, because this suburb between Mascot and Botany Bay carries a few site factors most suburbs do not — Botany Sands soil with an elevated water table, industrial-legacy contamination on remediated parcels near Port Botany, and the flight-path overlay.
None of those stop a rebuild; they just have to be designed for. The sands and water table shape the footing design off a real geotech, the contamination history is a due-diligence check near the port land, and the flight path calls for acoustic glazing. Heritage Conservation Areas sit in pockets including the Botany village.
The stock is Federation, inter-war and post-war fibro and brick on 400 to 700m² blocks, and the older homes carry asbestos, so a licensed strip-out leads the demolition.
We rebuild fixed-price, licence HBL 487805C. Get our feasibility, with the sands, water table and checks handled, before you commit.
Buildana manages the complete knockdown rebuild process in Botany — 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.

Design for the sands and the checks
Botany's site factors — the Botany Sands with an elevated water table, contamination history near the Port Botany land, and the flight-path overlay — do not stop a rebuild, but they have to be designed for. The footing design comes off a real geotech for the sands, and the acoustic glazing off the overlay.
On 400 to 700m² blocks, the aging stock suits a modern rebuild once those are handled.
Heritage pockets and asbestos
Heritage Conservation Areas sit in pockets including the Botany village, so a listed block goes down the DA path. Near the port land, the contamination due-diligence check is raised upfront.
The older stock carries asbestos, so a licensed strip-out and clearance certificate lead the demolition.

How It Works
From First Call to Final Key
KDR starts with an honest look at the existing house. Sometimes it's worth keeping. Most Botany homes from the 1910s–1970s — especially fibro and brick-veneer — are beyond the point where renovation makes sense. We tell you straight.
⏱Demolition is pre-approved to run parallel with rebuild design. Asbestos cleared, services abolished, site stripped in a single mobilisation. Geotech reconfirms Class M soil with the old house gone.
⏱New house goes up on the same footprint or a better one, whichever serves the block. Modern NCC envelope, better orientation, fit-for-purpose room sizes. The suburb stays the same; the house finally fits it.
⏱Final handover: new OC, six-year structural warranty, all the documentation on your Botany block you'd get on a greenfield build. The only difference is you still live in the street you chose.
