A knockdown rebuild in Bardwell Park 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.
Demolish and Rebuild in Bardwell Park
A knockdown rebuild in Bardwell Park is a solid family play — inter-war and post-war stock on 450 to 700m² blocks with its own station and the Bardwell Valley Reserve on the doorstep. The aging stock and decent block sizes suit a modern family rebuild.
The valley setting brings the site specifics: sandstone outcrops on the Wolli Creek valley fall can mean rock on the substructure, and riparian setbacks apply on the reserve-fronting blocks. Both are checked off a real geotech and survey upfront.
The ground is Wianamatta Shale with those outcrops, and the older stock carries asbestos, so a licensed strip-out leads the demolition.
We rebuild fixed-price, licence HBL 487805C. Get our feasibility, with the rock and riparian checked, before you commit.
Buildana manages the complete knockdown rebuild process in Bardwell Park — 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.

Family blocks by the valley
Bardwell Park's 450 to 700m² blocks, its own station and the Bardwell Valley Reserve make it a genuinely pleasant family suburb. The inter-war and post-war stock is well into rebuild territory, so a knockdown resets a dated home into a modern one.
The valley outlook on the reserve-side blocks is worth designing for.
Outcrops, riparian and old stock
Sandstone outcrops on the Wolli Creek valley fall can mean rock on the substructure, priced from a real geotech, and riparian setbacks apply on the reserve-fronting blocks, checked off the survey.
The older stock carries asbestos, so a licensed strip-out leads the demolition.

How It Works
From First Call to Final Key
Free site inspection of your Bardwell Park property. We check lot dimensions, Bayside 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 1930s–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 Bardwell Park is delivered under a fixed-price contract — site assessment through to defect-free handover.
