Old Toongabbie Granny Flat Construction — Fixed Price
Here is an arbitrage worth knowing: a granny flat in Old Toongabbie rents in the Westmead health precinct band, $520 to $750 a week, on land that costs $1.3M to $1.8M instead of Parramatta prices. Hospital shift workers do not mind being one suburb over when Toongabbie station is two kilometres away and buses run to Parramatta.
The suburb makes the build easy, too. The 1960s to 1980s brick homes sit on 500 to 750m² blocks with usable rear yards, and Wianamatta Shale takes a standard engineered slab on most lots. Parramatta's DCP treats R2 secondary dwellings conventionally, so a compliant design moves quickly.
What I would check first on an Old Toongabbie block: the rear-yard room, the shale slab, and any catch in the siting. Those set the plan.
We build these fixed-price, licence HBL 487805C. We will site it, price it fixed, and tell you straight if your block has a catch.
Buildana manages the full granny flat process in Old Toongabbie — 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.

Hospital shift workers do not mind being one suburb over when Toongabbie station is two kilometres away and buses run to Parramatta. That gap between rent and land cost is the arbitrage.

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 Old Toongabbie 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 Old Toongabbie'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.
