Bardwell Park Granny Flat Construction — Fixed Price
A granny flat builder in Bardwell Park works with the rail-line suburb between Bexley and Earlwood — inter-war heritage and post-war fibro and brick on 450 to 700m² blocks. Most clear the 450m² Housing SEPP threshold for a 60m² secondary dwelling, and with Bardwell Park station in the suburb on the T4 line, a studio lets steadily. Limited heritage stock means the fast CDC path is often open.
The Wolli Creek valley shapes the edge of the suburb. Blocks with fall toward the valley carry riparian setbacks off the Bardwell Valley Reserve, and sandstone outcrops appear on the valley fall — so the siting and footing are scoped off a real geotech. Away from the valley the blocks are straightforward.
The soil is Wianamatta Shale grading M with sandstone outcrops on the fall, so a stiffened-raft slab is engineered to suit. The post-war fibro stock means asbestos is likely in the original home, so a licensed strip-out leads where any demolition is involved.
We build fixed-price, licence HBL 487805C. Riparian setbacks and soil scoped first.
Buildana manages the full granny flat process in Bardwell Park — from site assessment and CDC fast-track approval through to fixed-price construction and handover. We build studio, 1-bedroom, and 2-bedroom designs up to the NSW maximum of 60m².

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. Free on-site assessment of your Bardwell Park property. We measure setbacks, check existing services, assess access, and confirm your 450–700m² block meets Bayside Council's requirements for a secondary dwelling. 60m² sounds tight on paper but designs well — high ceilings, good cross-ventilation, smart storage, and proper bedroom proportions make a 2-bed feel generous. We design for daily liveability, not just floor plan compliance.
⏱The Bardwell Park construction phase. Fixed price, programmed, supervised. CDC fast-track through a private certifier — typically approved in 10–15 business days. Bardwell Park is zoned R2 Low. Construction Certificate issued before works start. Your granny flat is built from slab to keys in a single programme. Engineered slab for Class M soil, frame, lock-up, fit-out, painting, flooring, and external works. 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. Defect-free inspection means we don't hand over a list to chase — every snag is fixed before keys move. Final clean, electrical and plumbing tested, smoke alarms certified, BASIX commissioning verified. The unit is rental-ready, not project-paperwork-ready.
⏱Quality Promise
We build Bardwell Park granny flats that hit the NSW 60m² maximum cleanly. Engineered slab, separate meter, rental-ready at handover.
