Building Granny Flats in Cremorne
Owning a detached house in Cremorne puts you in a small club, and that club is exactly who a granny flat works for here. Most of the suburb is apartments and townhouses along the Military Road spine, but the Federation and inter-war pockets on the side streets sit on 350 to 600m² blocks, and the bigger ones clear the 450m² SEPP line.
The reward for clearing it is a lower-north-shore rental band of $700 to $950 a week, with North Sydney three kilometres away and the ferry close. The constraint is space: on a 400m² lot the flat, the setbacks and the private open space have to be designed together or the application fails.
What I would check first on a Cremorne block: whether it clears the 450m² SEPP line, the space for the flat plus setbacks plus open space, and any heritage. Those decide it.
We build these fixed-price, licence HBL 487805C. We will tell you honestly whether your block carries it before you commit to drawings.
Buildana manages the full granny flat process in Cremorne — 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.

A small club of detached blocks

The bigger ones clear the 450m² SEPP line, so the first job is confirming yours does.

The constraint is space. On a 400m² lot the flat, the setbacks and the private open space have to be designed together or the application fails. Send us the address and we will tell you honestly whether the block carries it.

How It Works
From First Call to Final Key
We inspect your Cremorne block — lot size (typical 350–600m²), setbacks, services, access, Class M soil check and North Sydney Council requirements. You'll know if a granny flat is feasible before spending a dollar.
⏱Design phase covers layout, orientation on your Cremorne block, bathroom and kitchen placement, natural light, privacy screening, and entry path. You approve the design before we move to certification.
⏱Approval pack lodged with our preferred private certifier (Buildana works with several across the North Sydney 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 M 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.
