A knockdown rebuild in Greenacre costs $450,000–$1,200,000+. Standard single-storey from $450K, two-storey from $650K. Buildana manages demolition, Canterbury-Bankstown Council approvals, and construction under one fixed-price contract.
Greenacre Knockdown Rebuilds
A knockdown rebuild in Greenacre is a strong play on the aging fibro and brick stock, and the draw here is the block size. These are wide 550 to 800m² R2 lots holding 1950s to 1970s homes that are well overdue for renewal, so a rebuild gives you a large modern home with room to move.
The ground is Class M shale, which takes a standard engineered slab off a geotech without much fuss. The main demolition consideration is asbestos: the fibro-era homes usually carry it, so a licensed strip-out and clearance certificate lead the job.
Greenacre is R2 rather than R3, so this is a single-home rebuild suburb rather than a duplex one — but on blocks this generous, that single home can be a substantial build.

Wide blocks overdue for renewal
Greenacre's 550 to 800m² blocks are among the more generous in this part of Sydney, and much of the 1950s to 1970s stock is genuinely overdue for renewal. A knockdown rebuild here gives you a large single-level or two-storey home with a proper garden, not a home squeezed onto a tight lot.
It is a family-focused suburb, so a well-planned rebuild that uses the block properly tends to hold its value.
Single-home suburb, asbestos first
Greenacre is zoned R2, so a duplex is not on the table here — this is a single-home rebuild suburb, which keeps the planning path simple. On blocks this wide, that single home can still be substantial.
The fibro-era stock means a licensed asbestos strip-out and clearance certificate lead the demolition, priced into the feasibility from the start. The Class M shale takes a standard slab off a geotech.

How It Works
From First Call to Final Key
Free site inspection of your Greenacre property. We check lot dimensions, Canterbury-Bankstown Council's planning controls, existing home condition, and potential asbestos.
⏱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.
⏱Licensed demolition of existing 1950s–1970s-era dwelling. Asbestos removal by certified contractors (if present).
⏱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.
⏱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 Greenacre is delivered under a fixed-price contract — site assessment through to defect-free handover.
