A granny flat in St Peters depends on the block, and the ground. This small inner west suburb on the Sydenham-to-Bankstown corridor is Victorian terraces, Federation cottages, inter-war heritage and former industrial conversions on 150 to 400m² blocks — the larger freestanding cottages clear the 450m² Housing SEPP threshold and can take a studio, while the terraces can't, so the survey is the honest first step.
The industrial history matters here. Remediated parcels around the WestConnex/M8 corridor and the former brick pit carry industrial-legacy contamination, so any build on those needs contamination management handled and documented. Heritage Conservation Areas in pockets can add a full DA.
The soil is Wianamatta Shale grading M, so a stiffened-raft slab is engineered off a real geotech on the reactive ground. The old stock can carry fibro, so a licensed asbestos strip-out leads where any demolition is involved.
We build fixed-price, licence HBL 487805C. Survey, contamination and heritage scoped first.
Buildana manages the full granny flat process in St Peters — 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.

Depends on block and ground
St Peters is terraces, cottages, heritage and industrial conversions on 150 to 400m² blocks — the larger freestanding cottages clear the 450m² Housing SEPP threshold, while terraces can't.
The survey is the honest first step, and a studio on a qualifying block lets well near the station.
Contamination and heritage
Remediated parcels around the WestConnex/M8 corridor and the former brick pit carry industrial-legacy contamination, so those need contamination management handled and documented.
Heritage pockets can add a DA, and the shale means a stiffened-raft slab off a geotech.
