A knockdown rebuild in Eastgardens costs $450,000–$1,200,000+. Standard single-storey from $450K, two-storey from $650K. Buildana manages demolition, Bayside Council approvals, and construction under one fixed-price contract.
Eastgardens Knockdown Rebuilds
A knockdown rebuild in Eastgardens suits the tired post-war stock around the Westfield-anchored centre, but the sandy ground and flight path shape any rebuild. The homes sit on 400 to 700m² blocks, and the Botany Sands soil means the new slab and footings get designed against groundwater. Some streets sit under the ANEF flight-path overlay, and R3/R4 zoning near the centre can suit redevelopment instead.
The Botany Sands ground can carry an elevated water table, so the new slab is engineered against groundwater from a real geotech. The flight-path overlay brings acoustic requirements on affected streets. Where the older home carries asbestos, a licensed strip-out and clearance certificate lead the demolition.
What I check first on your Eastgardens knockdown rebuild: whether R3 or R4 zoning near the centre suits redevelopment, the water table on the sandy ground, and the flight-path overlay. Those decide the play.

Rebuild or redevelop near the centre
Eastgardens is anchored by Westfield and carries R3/R4 zoning around the centre, so on a block near the commercial core a redevelopment can beat a single knockdown rebuild. On the standard residential blocks, where the post-war stock has tired, a single rebuild is a genuine play. So the first thing I do is check your zoning.
Either way, the sandy ground shapes the rebuild fundamentals, so it gets assessed early rather than assumed.
Sandy ground and flight path
The Botany Sands ground under Eastgardens can carry an elevated water table, so the new slab and footings are engineered against groundwater from a real geotech, sometimes with a suspended slab. Some streets sit under the ANEF flight-path overlay, which brings acoustic construction requirements on the new home. Where the older home carries asbestos, a licensed strip-out and clearance certificate lead the demolition. I check the ground, overlay and clearance on your block first.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. We assess your Eastgardens block — lot size (typical 400–700m²), R2 Low 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 Bayside Council requires. Approval managed start to finish.
⏱The Eastgardens construction phase. Fixed price, programmed, supervised. 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.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. 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.
