Potts Hill Granny Flat Construction — Fixed Price
Small suburb, clean case: a granny flat in Potts Hill sits on 500 to 700m² of Class M soil, a kilometre from Birrong station, and rents for $380 to $520 a week. The post-war housing stock leaves workable backyards, the slab engineering is conventional, and the reservoir parklands keep the streets quiet, the kind of steady, unglamorous setup that makes secondary dwellings pay.
With medians at $1.0M to $1.3M, owners here are often building for family as much as yield, a parent moving closer, a kid staying local. The build path is the same either way: confirm the 450m² threshold, check services and stormwater, fix the price.
What I would check first on a Potts Hill block: the 450m² threshold, the services and stormwater, and the Class M slab. Those confirm the build.
We build these fixed-price, licence HBL 487805C. We handle all three before you commit, and the first assessment is on us.
Buildana manages the full granny flat process in Potts Hill — 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.

Small suburb, clean case
A Potts Hill granny flat sits on 500 to 700m² of Class M soil, a kilometre from Birrong station, renting for $380 to $520 a week. The post-war stock leaves workable backyards, the slab engineering is conventional, and the reservoir parklands keep the streets quiet.
It is the kind of steady, unglamorous setup that makes secondary dwellings pay without drama.
Family as much as yield
At $1.0M to $1.3M medians, owners here are often building for family as much as yield, a parent moving closer or a kid staying local.
The build path is the same either way: confirm the 450m² threshold, check services and stormwater, fix the price. We handle all three before you commit, and the first assessment is on us.

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 Potts Hill 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 Potts Hill'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
Potts Hill granny flat construction done to a schedule. CDC lodged, slab poured, handover complete — on one fixed-price contract.
