Granny Flats Designed for Hunters Hill Blocks
Hunters Hill is one of the most heritage-protected suburbs in Sydney, and that's the single biggest fact for a granny flat here. Heritage Conservation Areas cover virtually the entire suburb, so almost any second dwelling goes down the DA path with a design that has to sit sympathetically on a sandstone-and-mansion streetscape. This is never a fast-track, and rarely a yield play.
The blocks are generous — 500 to 1,200m² — so space usually isn't the limiter. At these values a granny flat is a quality studio, guest quarters or multigenerational accommodation, built to a standard that suits a heritage home. The deep sandstone and the harbour fall are the technical work.
Most blocks fall to the Lane Cove or Parramatta River, so a second dwelling often sits on a stepped or suspended footing, with rock excavation to get in — commonly $40,000 to $140,000 above a standard substructure. Water-frontage lots carry the Foreshore Building Line and a Crown Lands referral.
I build these to the standard the suburb expects — fixed price with the heritage, rock, fall and foreshore all worked out first. Licence HBL 487805C.
Buildana manages the full granny flat process in Hunters 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.

Heritage covers almost everything
With Heritage Conservation Areas across virtually the whole suburb, a granny flat in Hunters Hill is a DA almost every time, with a design that respects the sandstone-and-mansion character. That's more process and more design care, and in a suburb like this it's warranted — the heritage is exactly why people are here.
At Hunters Hill values, the point is rarely rental yield. It's usually a quality studio, guest quarters or accommodation for family, built to match a heritage home rather than dropped in the yard.
Deep rock, fall and foreshore
Most blocks fall to the Lane Cove or Parramatta River, so a second dwelling often steps down the site or sits on a suspended footing. The sandstone means rock excavation to get in — commonly $40,000 to $140,000 above a standard substructure — so I get a geotech bore first because guessing the rock here is expensive.
Water-frontage lots carry the Foreshore Building Line and a Crown Lands referral, which shape where anything can go. I map all of that before I quote so it's in the fixed price.

How It Works
From First Call to Final Key
Free on-site assessment of your Hunters Hill property. We measure setbacks, check existing services, assess access, and confirm your 500–1,200m² (premium Federation/Victorian/inter-war heritage predominant); 800–2,000m²+ harbour-front (Woolwich/Hunters Hill peninsula tip) block meets Hunters Hill Council's requirements for a secondary dwelling.
⏱60m² sounds tight on paper but designs well — high ceilings, good cross-ventilation, smart storage, and proper bedroom proportions make a 2-bed feel generous. We design for daily liveability, not just floor plan compliance.
⏱CDC fast-track through a private certifier — typically approved in 10–15 business days. Hunters Hill is zoned R2 Low Density. Construction Certificate issued before works start.
⏱Your granny flat is built from slab to keys in a single programme. Engineered slab for Class Hawkesbury Sandstone bedrock soil, frame, lock-up, fit-out, painting, flooring, and external works. Quality inspections at every stage.
⏱Defect-free inspection means we don't hand over a list to chase — every snag is fixed before keys move. Final clean, electrical and plumbing tested, smoke alarms certified, BASIX commissioning verified. The unit is rental-ready, not project-paperwork-ready.
⏱Quality Promise
We build Hunters Hill granny flats that hit the NSW 60m² maximum cleanly. Engineered slab, separate meter, rental-ready at handover.
