A granny flat in Asquith costs $150,000–$300,000+ depending on size and finishes. 1-bed from $150K, 2-bed from $200K. CDC fast-track approval in 10–15 business days. Buildana manages design, Hornsby Shire Council approval and fixed-price construction.
Asquith Granny Flat Construction — Fixed Price
Asquith has its own station and is seeing real renewal — R3 and R4 redevelopment around the station, with older Federation cottages and brick homes on 600 to 900m² blocks on the wider streets. On those residential blocks a granny flat works well, and the station gives it a commuter rental market.
Around the station itself the R3/R4 zoning is apartment land, where a granny flat is the wrong tool — I'll tell you so. On the R2 streets it's a solid, well-supported build.
The ground is Hawkesbury Sandstone, so rock excavation is common — usually $30,000 to $120,000 above standard — and some bushland-fringe blocks carry a BAL rating. Both are checked before I quote.
Fixed price with the zoning, rock and bushfire all sorted first. Licence HBL 487805C.
Buildana manages the full granny flat process in Asquith — 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.

Station-side, on the right block
Asquith's station is what lifts it for a granny flat — a tidy flat here lets to commuters, not just to people after the space. On the R2 residential streets there's room to build one properly on 600 to 900m² blocks.
Around the station the R3/R4 zoning is apartment land, so if your block sits there, redevelopment is the play rather than a granny flat. I check which side of that line you're on first.
Sandstone rock, tested first
The Hawkesbury Sandstone means rock excavation is common — usually $30,000 to $120,000 above a standard substructure — so I get a geotech bore and put the rock in the fixed price rather than guessing it.
Some bushland-fringe blocks carry a BAL rating, which I check on the mapping. A well-built flat near the station lets steadily, though I won't put a weekly figure in writing I can't back.

How It Works
From First Call to Final Key
Free on-site assessment of your Asquith property. We measure setbacks, check existing services, assess access, and confirm your 700–1,200m² typical (Hornsby/Asquith/Pennant Hills/Beecroft/Wahroonga boundary/Cherrybrook); 1–5ha acreage (Galston/Berrilee/Arcadia/Forest Glen/Glenorie/Berowra Heights bushland fringe) block meets Hornsby Shire 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. Asquith is zoned R2.
⏱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.
⏱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.
