Quick Answer
A home extension in Bardwell Park costs $150,000–$600,000+. Rear extension from $150K, second-storey addition from $300K. Buildana manages design, Bayside Council approvals, and construction under one fixed-price contract.
Bardwell Park Home Extensions & Additions
A home extension in Bardwell Park should be designed toward the valley. The inter-war and post-war homes on 450 to 700m² blocks sit beside the Wolli Creek green, and that quiet reserve is the pocket's real asset — so the wing that works opens the living toward it rather than turning its back on it.
On the reserve-side lots the riparian setbacks shape the rear envelope, so the wing is designed from those constraints outward. The era fabric gets licensed lead and asbestos handling, and the valley-fall sandstone is read wherever the structure changes.
At a $1.7M to $2.5M median, a wing beats the cost of upsizing out of a valley pocket like this — the green and the quiet are exactly what you keep by building, and the rail keeps daily life practical.

The wing faces the valley
Bardwell Park's Wolli Creek green is the quiet asset, and the wing opens toward it — designed within the riparian setbacks on the reserve-side lots.
The rail keeps the pocket practical through the build.
Era and edges handled
The era fabric gets licensed handling wherever the work opens it up.
The valley-fall sandstone is read where the structure changes, and all of it is priced into the job from the outset.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. Free consultation at your Bardwell Park home. We inspect the existing structure, check Bayside Council's controls, measure available space, and discuss what you need. You get a clear scope, budget range, and timeline before committing. Two design moves are usually on the table: match the existing house so the extension reads as original, or contrast with it so the new section is clearly modern. Both work — choice is aesthetic, and we'll show 3D renders of both before you commit.
⏱The Bardwell Park construction phase. Fixed price, programmed, supervised. CDC (10–15 business days) or DA through Bayside Council depending on scope. Structural engineering, BASIX, and all documentation prepared and lodged. Construction Certificate obtained. Construction phase connects new to existing — footings, frame, roof tie-in, waterproofing at junction, internal fit-out and external finish. Staged works minimise disruption to your daily routine in Bardwell Park.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Final inspection focuses on the integration: paint blend, flooring transitions, ceiling height, junction waterproofing, sound transmission. The extension shouldn't feel bolted on — it should feel like the house was always meant to be this size.
