Granny Flat Builder in Bellevue Hill
A granny flat in Bellevue Hill is a premium, family-driven build to the highest standard, not a yield exercise. On 500 to 2,000m² blocks worth $6M to $25M and beyond, a secondary dwelling is guest accommodation, staff quarters, a studio or multigenerational space — the lot clears the 450m² Housing SEPP threshold many times over, so size is never the question.
Heritage and site decide the job. Heritage Conservation Areas cover several streets, so a secondary dwelling goes through a full DA rather than the fast CDC path. And the sandstone-dominant ground with substantial fall on the north-facing slopes means engineered slabs, substantial retaining and rock excavation.
So I scope the heritage and the rock first, and design a dwelling worthy of one of Sydney's most premium addresses. This is architect-led work from day one.
We build to that standard, fixed-price, licence HBL 487805C.

Premium, family-driven
On 500 to 2,000m² blocks worth $6M to $25M and beyond, a Bellevue Hill secondary dwelling is guest accommodation, staff quarters, a studio or multigenerational space — not a weekly-rent play. The lot clears the 450m² Housing SEPP threshold many times over.
It's designed to be worthy of one of Sydney's most premium addresses.
Heritage and rock
Heritage Conservation Areas cover several streets, so a secondary dwelling goes through a full DA — scoped first.
Sandstone ground with substantial fall on the north-facing slopes means engineered slabs, substantial retaining and rock excavation off a real geotech.

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