Building Granny Flats in Eastlakes
A granny flat in Eastlakes depends on the block, and much of the suburb is changing. This inland suburb between Mascot and Pagewood is post-war brick, mid-century walk-up flats and contemporary apartments on 350 to 650m² blocks, with heavy R3 and R4 redevelopment around the Eastlakes shops — the larger settled R2 lots clear the 450m² Housing SEPP threshold and can take a studio, while the redevelopment zone is geared to apartments, so the survey and zoning come first.
Where a block qualifies, Mascot and its transport are close, so a studio lets well. The ANEF flight-path overlays can require acoustic treatment — upgraded glazing and insulation — for aircraft noise, which the design accounts for.
The soil is Botany Sands, so the footing is engineered off a real geotech — a sand-appropriate slab or pad design. The older stock can carry fibro, so a licensed asbestos strip-out leads where any demolition is involved.
We build fixed-price, licence HBL 487805C. Survey, zoning, flight-path and soil scoped first.
Buildana manages the full granny flat process in Eastlakes — 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 changing suburb
Eastlakes is post-war brick, walk-up flats and apartments on 350 to 650m² blocks with heavy R3/R4 redevelopment around the shops — the larger settled R2 lots clear the 450m² Housing SEPP threshold, while the redevelopment zone is geared to apartments.
The survey and zoning come first, and a qualifying studio lets well with Mascot close.
Sand and flight path
The Botany Sands soil means the footing is engineered off a geotech — a sand-appropriate design.
The flight-path overlays can require acoustic treatment — upgraded glazing and insulation — for aircraft noise.

How It Works
From First Call to Final Key
Free on-site assessment of your Eastlakes property. We measure setbacks, check existing services, assess access, and confirm your 350–650m² block meets Bayside 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. Eastlakes 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 M 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.
