Granny Flat Builder in Hillsdale
A granny flat builder in Hillsdale works with a post-war inland pocket adjoining Eastgardens — fibro and brick on 500 to 650m² blocks, plus public-housing pockets. The private blocks clear the 450m² Housing SEPP threshold comfortably, so a 60m² secondary dwelling is achievable on most, and with limited heritage stock the fast CDC path is often open.
The economics work here: Hillsdale is an affordable entry point in the Randwick LGA, close to the Eastgardens shopping and employment precinct, so a studio adds solid yield without the coastal price tags.
The ground is sandstone, so the slab is conventional and engineered off a geotech. 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. Soil and asbestos scoped first.
Buildana manages the full granny flat process in Hillsdale — 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.

Affordable and straightforward
Hillsdale's private 500 to 650m² blocks clear the 450m² Housing SEPP threshold comfortably, so a 60m² secondary dwelling is achievable on most.
With limited heritage stock, the fast CDC path is often open, and Eastgardens is close for shopping and work.
Sandstone and fibro
The sandstone ground keeps the slab conventional off a geotech.
The post-war fibro stock means asbestos is likely in the original home, so a licensed strip-out leads where demolition is involved.

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 Hillsdale 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 Hillsdale'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.
