Granny Flats Designed for Five Dock Blocks
A granny flat builder in Five Dock works with the inland village heart of the LGA — Federation and inter-war cottages, Italian-Australian post-war stock and contemporary infill on 450 to 800m² blocks. Most clear the 450m² Housing SEPP threshold for a 60m² secondary dwelling, and with Sydney Metro West set to deliver a Five Dock station in 2030, a studio here has a strong rental future.
Zoning and heritage are the first checks. R3 along Great North Road and Lyons Road permits medium-density, so on those a secondary dwelling isn't the highest use — it suits the settled R2 blocks. Heritage Conservation Areas cover several streets and can push a job to a full DA rather than the fast CDC path.
The soil is Wianamatta Shale grading M to H, 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. Zoning, heritage and soil scoped first.
Buildana manages the full granny flat process in Five Dock — 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.

Village blocks, Metro coming
Five Dock's 450 to 800m² blocks mostly clear the 450m² Housing SEPP threshold, so a 60m² secondary dwelling works well on most.
With Sydney Metro West delivering a Five Dock station in 2030, a studio here has a strong rental future.
Zoning, heritage and shale
R3 along Great North Road and Lyons Road is the higher use, so a granny flat suits the settled R2 blocks, and heritage can add a DA.
The Wianamatta Shale grading M to H 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 Five Dock 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 Five Dock'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.
⏱Quality Promise
Our Five Dock granny flat builds run on CDC fast-track where eligible. 10–15 business days to approval, 12 weeks to handover, fixed price.
