Building Granny Flats in Bexley
A granny flat builder in Bexley works with the established suburb west of Rockdale — Federation cottages, inter-war heritage and post-war brick on 450 to 700m² blocks. Most clear the 450m² Housing SEPP threshold for a 60m² secondary dwelling, so a studio or family space works well in this settled Federation and inter-war streetscape.
Heritage is the first check. Heritage Conservation Areas cover pockets of the suburb, so a secondary dwelling there can go through a full DA rather than the fast CDC path, while R3 along Forest Road is geared to medium-density. Away from those, the standard controls apply.
The soil is Wianamatta Shale grading M, so a stiffened-raft slab is engineered off a real geotech on the reactive ground. The older stock can carry fibro, so a licensed asbestos strip-out leads where any demolition is involved.
We build fixed-price, licence HBL 487805C. Heritage, zoning and soil scoped first.
Buildana manages the full granny flat process in Bexley — 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.

Settled Federation blocks
Bexley's 450 to 700m² blocks mostly clear the 450m² Housing SEPP threshold, so a 60m² secondary dwelling works well on most.
It's a settled Federation and inter-war streetscape where a studio suits family or rental use.
Heritage and shale
Heritage Conservation Areas in pockets can push a secondary dwelling to a full DA, while R3 along Forest Road is geared to medium-density — I check both first.
The Wianamatta Shale grading M means a stiffened-raft slab engineered off a geotech, and older stock can carry fibro.

How It Works
From First Call to Final Key
We inspect your Bexley block — lot size (typical 450–700m²), setbacks, services, access, Class M soil check and Bayside Council requirements. You'll know if a granny flat is feasible before spending a dollar.
⏱Design phase covers layout, orientation on your Bexley block, bathroom and kitchen placement, natural light, privacy screening, and entry path. You approve the design before we move to certification.
⏱Approval pack lodged with our preferred private certifier (Buildana works with several across the Bayside area). They've reviewed our designs before, know our documentation standard, and turn approvals around at the fast end of the legislated window.
⏱Construction runs 10–16 weeks from slab pour. Class M engineered slab, timber or steel frame, Colorbond roof, full internal fit-out, and separate service connections.
⏱Handover documentation includes everything you need to list with a property manager: OC, BASIX, structural cert, appliance manuals, separate metering details. Photos for the listing taken before furniture goes in.
⏱Quality Promise
