A granny flat in Ashfield depends on the block. This rail-line commercial centre is Federation cottages, inter-war heritage, terraces and contemporary apartments on 250 to 500m² blocks — the larger freestanding cottages clear the 450m² Housing SEPP threshold and take a studio well, while the terraces and strata apartments often can't, so the survey is the honest first step.
Where a block qualifies, the case is strong: Ashfield station is in the suburb and rental demand is steady. R4 around the station precinct is geared to apartments, so a secondary dwelling suits the settled blocks away from it, and Heritage Conservation Areas in pockets can add a full DA rather than the fast CDC path.
The soil is Wianamatta Shale grading M, so a stiffened-raft slab is engineered off a real geotech on the reactive ground. 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 and heritage scoped first.
Buildana manages the full granny flat process in Ashfield — 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 the block
Ashfield is cottages, heritage, terraces and apartments on 250 to 500m² blocks — the larger freestanding cottages clear the 450m² Housing SEPP threshold, while terraces and strata apartments often can't.
The survey is the honest first step, and a qualifying studio lets steadily with the station in the suburb.
Zoning, heritage and shale
R4 around the station is geared to apartments, so a granny flat suits the settled blocks away from it, and heritage pockets can add a DA.
The Wianamatta Shale grading M means a stiffened-raft slab engineered off a geotech, and older stock can carry fibro.
