A knockdown rebuild in Bexley 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.
Bexley KDR — Single Contract, New Home
A knockdown rebuild in Bexley depends heavily on your street, because this suburb has established Federation and inter-war streetscapes with Heritage Conservation Areas in pockets. On a heritage-listed street, demolition is restricted and the answer is usually a sensitive renovation rather than a knockdown. On the non-heritage R2 blocks, a rebuild of tired post-war stock is a genuine play.
The Wianamatta Shale ground is reactive, so the new slab is engineered off geotech. Where the older home carries asbestos, a licensed strip-out and clearance certificate lead the demolition. The first and most important check is whether your block sits inside a Heritage Conservation Area.
What I check first on your Bexley knockdown rebuild: whether you sit inside a Heritage Conservation Area where demolition is restricted, the reactive clay for the new slab, and asbestos in the demolition. Those decide whether a rebuild is even on the table.

Heritage decides whether you can knock down
Bexley has some of the more intact Federation and inter-war streetscapes in the area, and Heritage Conservation Areas cover pockets of the suburb. On a contributing home inside an HCA, demolition is heavily restricted, so a knockdown rebuild is off the table and the answer is a sensitive renovation that keeps the period character. I would rather establish that from the heritage layer than have a rebuild refused.
On the non-heritage R2 blocks, where the post-war stock has tired, a rebuild is a genuine play. So the first thing I do is check whether your block sits inside a Conservation Area.
Slab and asbestos
Where a rebuild does stack up, the reactive shale under Bexley means the new slab is engineered off a real geotech to stay stable against clay movement. Where the older home carries asbestos, a licensed strip-out and clearance certificate lead the demolition before the rebuild. I map the heritage, the ground and the clearance as part of the feasibility.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. Free site inspection of your Bexley property. We check lot dimensions, Bayside Council's planning controls, existing home condition, and potential asbestos. Written assessment with budget estimate within 5 business days. KDR is the chance to get the design right — the new build doesn't have to mimic the original layout. We start from your block's strengths (orientation, slope, views) and your family's brief, then design the home the original lot always deserved.
⏱The Bexley construction phase. Fixed price, programmed, supervised. Licensed demolition of existing 1910s–1960s-era dwelling. Asbestos removal by certified contractors (if present). Site cleared, levelled, and ready for new slab. Typically 1–2 weeks. Your new home goes up on the cleared site. Engineered slab sized for Class M soil, frame, roof, fit-out, kitchen, bathrooms, flooring, painting, driveway, and landscaping. Quality inspections at every stage.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Handover pack: OC, structural certificates, BASIX, appliance manuals and warranties, paint colour schedule, maintenance plan, and the keys. Six-year structural warranty kicks in from OC date — keep the documentation safe for any future sale.
⏱Quality Promise
Every Buildana knockdown rebuild in Bexley is delivered under a fixed-price contract — site assessment through to defect-free handover.
