Ingleside Granny Flat Construction — Fixed Price
Ingleside is acreage — 1 to 5 hectare-plus RU2 holdings in the bush behind the beaches, horticultural and equestrian in character. A granny flat here is a rural second dwelling, and the constraints are the serious rural ones: heavy bushfire, deep sandstone, on-site servicing, and a drinking-water-catchment overlay on parts of the western edge.
On RU2 land the second dwelling generally goes through a development application, not the complying-development route. On acreage that's fine — there's endless room to site it well — but the DA carries real assessment because of the environmental overlays out here.
The bushfire rating is universal and often severe — BAL-29 up to Flame Zone — so the RFS building requirements aren't optional, they shape the whole design. The sandstone is deep too, so rock excavation can run $80,000 to $200,000-plus, and there's no sewer, so the flat needs an on-site wastewater system.
I build these fixed-price with the DA, bushfire, rock, servicing and any catchment controls all worked out first. Licence HBL 487805C.

Bushfire is the dominant factor
Ingleside's bushfire ratings are among the most serious you'll deal with anywhere — BAL-29 to Flame Zone is normal here, not exceptional. That drives everything: the construction, the materials, the defendable space, the firefighting water supply. A second dwelling has to be designed to the RFS requirements from the ground up, and I'd rather you understand that up front than discover it at DA stage.
There's also a drinking-water-catchment overlay on parts of the western edge, which adds another layer to the assessment. I check whether your block is affected before I quote.
Deep rock and off-grid servicing
The sandstone out here is deep, so rock excavation can be a heavy cost — $80,000 to $200,000-plus on some blocks. I get a proper geotech bore, because on acreage like this a guess on the rock is a guess on tens of thousands of dollars.
Off sewer, the flat runs on tank water and an on-site wastewater system sized for the extra load. Vehicle access has to suit both the build and emergency services. I sort all of it before the fixed price is set.

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 Ingleside 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 Ingleside'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
Buildana Ingleside granny flats: designed for your block, built to CDC standards, delivered under a fixed-price contract.
