Queenscliff Granny Flat Construction — Fixed Price
Queenscliff is the oceanfront suburb at the northern end of Manly beach — tighter blocks, from 350 to 700m², with Federation beach houses and inter-war heritage across the older streets. A granny flat here is workable on the larger blocks and constrained on the smaller heritage ones.
The heritage overlays mean many viable builds go down the DA path with a design that respects the streetscape. On the tighter 350 to 450m² blocks, once you count the existing house, setbacks and separation, there may not be room for a compliant second dwelling — so I survey before I promise anything.
Underneath is Hawkesbury Sandstone, often on a fall, so rock excavation is real and can be deep — commonly $50,000 to $130,000. The beachfront sits in the coastal hazard zone, and the Manly Lagoon margin has acid sulphate soils.
Fixed price with the heritage, coastal, soil and rock all checked first. Licence HBL 487805C.

The block size does a lot of deciding
Queenscliff blocks run tighter than most of the Northern Beaches — down to 350m² — so on the smaller lots the existing house and setbacks can leave little room for a compliant second dwelling. I won't promise a layout on a tight block sight unseen; I get the survey and tell you straight what fits.
On the larger blocks there's more to work with, though the heritage overlays across the older streets usually mean a DA with a sympathetic design.
Deep rock and coastal soils
The sandstone often sits on a fall here, so rock excavation is real and can be deep — commonly $50,000 to $130,000. I get a geotech bore first because guessing the rock on a Queenscliff block is expensive.
The beachfront carries the coastal hazard zone, and the Manly Lagoon margin has acid sulphate soils that the footing has to be designed around. I check whichever applies to your block before quoting.

How It Works
From First Call to Final Key
Free on-site assessment of your Queenscliff property. We measure setbacks, check existing services, assess access, and confirm your 350–700m² block meets Northern Beaches 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. Queenscliff is zoned R2 Low. 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 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
Every Buildana granny flat in Queenscliff is built under a fixed-price contract with full Queenscliff council compliance and a 6-year structural warranty.
