Coogee Granny Flat Construction — Fixed Price
A granny flat in Coogee depends on the block. The LGA's signature beachside suburb mixes Federation cottages, inter-war heritage, mid-century apartments and contemporary on 250 to 600m² blocks — the larger freestanding lots clear the 450m² Housing SEPP threshold and can take a studio, while the tighter and strata blocks often can't, so the survey is the honest first step.
Where a block qualifies, a studio near Coogee Beach lets strongly. Heritage Conservation Areas cover most older streets, so those go through a full DA rather than the fast CDC path, and the R3 corridors along Coogee Bay Road and Carrington Road may suit medium-density over a granny flat. The substantial fall to the beach adds engineering on the steeper lots.
The ground is sandstone-dominant, so any build is engineered off a real geotech. Coastal salt-grade specification is mandatory here — marine-grade fixings and corrosion-resistant detailing. 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. Survey, zoning, heritage and fall scoped first.
Buildana manages the full granny flat process in Coogee — 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.

Depends on the block

Heritage, fall and salt air
Heritage over most older streets means a full DA, and the R3 corridors may suit medium-density over a granny flat. The fall to the beach adds engineering on steeper lots.

How It Works
From First Call to Final Key
Granny flats get underestimated. A lot of builders treat them as a kit-home product. We don't. Your Coogee block has a main dwelling, a driveway, service connections, trees, and neighbours — the secondary dwelling gets designed around those realities.
⏱The 60m² SEPP cap is not a suggestion. Every millimetre gets used — kitchen, bathroom, laundry, living, bedroom, storage — with the envelope tuned for Coogee's sun and prevailing breeze. Real rooms, not compromise spaces.
⏱CDC gets lodged through a private certifier the week design locks in. 10–15 business days later, slab starts. The trades sequence tight because the footprint is small — one plumber, one sparkie, one tiler, one programme.
⏱Handover gives you a genuinely rentable second home. Separate meter, independent hot water, standalone bathroom, full kitchen. Ready to lease on handover day, not a 'studio' that needs another $20K of finishing.
⏱Quality Promise
Coogee granny flat construction done to a schedule. CDC lodged, slab poured, handover complete — on one fixed-price contract.
