Building Granny Flats in Wheeler Heights
A granny flat builder in Wheeler Heights works with the elevated post-war suburb — 1950s–1970s brick on 500 to 800m² R2 blocks with sandstone topography and ocean views from the eastern fall. Most clear the 450m² Housing SEPP threshold for a 60m² secondary dwelling, so a studio works well in this quiet residential suburb.
The main thing to price properly here is the ground. The Hawkesbury Sandstone means rock excavation is typical where the slab meets stone — a real cost scoped off a geotech, not guessed. On the sloping eastern-fall blocks with ocean views, the fall also shapes the substructure and siting.
Any footing is engineered off a real geotech to suit the sandstone and any fall. The older brick stock can carry fibro in later additions, so a licensed asbestos strip-out leads where any demolition is involved.
We build fixed-price, licence HBL 487805C. Rock, fall and soil scoped first.
Buildana manages the full granny flat process in Wheeler Heights — 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.

It's a quiet residential suburb where a studio suits family or a steady rental.
Sandstone and fall
The Hawkesbury Sandstone means rock excavation is typical, scoped off a geotech, not guessed.
On the sloping eastern-fall blocks the fall shapes the substructure and siting — engineered off a geotech.

⏱Approval pack lodged with our preferred private certifier (Buildana works with several across the Northern Beaches area). They've reviewed our designs before, know our documentation standard, and turn approvals around at the fast end of the legislated window.
⏱Construction runs 10–16 weeks from slab pour. Class Hawkesbury Sandstone engineered slab, timber or steel frame, Colorbond roof, full internal fit-out, and separate service connections.
⏱Handover documentation includes everything you need to list with a property manager: OC, BASIX, structural cert, appliance manuals, separate metering details. Photos for the listing taken before furniture goes in.
