Dulwich Hill Granny Flat Construction — Fixed Price
A granny flat in Dulwich Hill depends on the block. This rail-line suburb between Marrickville and Lewisham is Federation cottages, inter-war heritage, terraces and contemporary apartments on tight 200 to 450m² blocks, with extensive Heritage Conservation Areas — so a detached secondary dwelling is only viable on the larger freestanding cottages that clear the 450m² Housing SEPP threshold, and the survey plus heritage check is the honest first step.
Where a block qualifies, the station and light rail make a studio genuinely lettable. But the terraces that make up much of the suburb don't have the room, and heritage means a full DA rather than the fast CDC path — so I'm upfront about what your block can and can't take.
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, heritage and soil scoped first.
Buildana manages the full granny flat process in Dulwich Hill — 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
Dulwich Hill is cottages, heritage, terraces and apartments on tight 200 to 450m² blocks with extensive heritage — so a detached secondary dwelling is only viable on the larger freestanding cottages that clear the 450m² Housing SEPP threshold.
The survey and heritage check come first, and a qualifying studio lets well with the station and light rail close.
Heritage and shale
The terraces don't have the room, and heritage means a full DA rather than CDC — I'm upfront about what your block can take.
The Wianamatta Shale grading M means a stiffened-raft slab engineered off a geotech, and older stock can carry fibro.

How It Works
From First Call to Final Key
Granny flats get underestimated. A lot of builders treat them as a kit-home product. We don't. Your Dulwich Hill block has a main dwelling, a driveway, service connections, trees, and neighbours — the secondary dwelling gets designed around those realities.
⏱The 60m² SEPP cap is not a suggestion. Every millimetre gets used — kitchen, bathroom, laundry, living, bedroom, storage — with the envelope tuned for Dulwich Hill's sun and prevailing breeze. Real rooms, not compromise spaces.
⏱CDC gets lodged through a private certifier the week design locks in. 10–15 business days later, slab starts. The trades sequence tight because the footprint is small — one plumber, one sparkie, one tiler, one programme.
⏱Handover gives you a genuinely rentable second home. Separate meter, independent hot water, standalone bathroom, full kitchen. Ready to lease on handover day, not a 'studio' that needs another $20K of finishing.
