A granny flat in Putney is shaped by the river. This riverside suburb on the Parramatta River is Federation cottages, inter-war heritage and contemporary river-fall on 550 to 850m² blocks — most clear the 450m² Housing SEPP threshold, so a secondary dwelling is achievable, with the Putney Wharf ferry to Mortlake a genuine drawcard for a studio.
Heritage and fall shape the job. Heritage Conservation Areas cover the village core, so those go through a full DA rather than the fast CDC path, and the substantial fall to the river drives suspended slab engineering on the water-facing lots.
The soil is Wianamatta Shale grading M, with H and sandstone outcrops on the river-fall edge, so the footing is engineered off a real geotech — a stiffened raft on the flatter ground, a suspended slab where the fall demands. 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. Heritage, fall and soil scoped first.
Buildana manages the full granny flat process in Putney — 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.

How It Works
From First Call to Final Key
Most Putney blocks support a granny flat — the question is where it sits, how it accesses the street, and how it shares the yard with the main house. We work that out on site, with the existing house and existing services in front of us.
⏱1-bed or 2-bed floor plan designed for your Putney block — up to the NSW maximum of 60m². Layout, window placement, kitchen and bathroom positioning optimised for liveability and rental appeal.
⏱We lodge your CDC application with all required documentation — BASIX, plans, site analysis, stormwater. Private certifier approval in 10–15 business days.
⏱12-week typical timeline for a 60m² 2-bed: slab pour week 1, frame stand weeks 2–3, lock-up week 5, internal fit-out weeks 6–10, finishes and external works weeks 11–12. We provide the dated programme upfront so you can plan move-in or tenant placement.
⏱OC issued, defect-free inspection completed, keys handed over. Your granny flat is ready to occupy or lease.
