Granny Flats Designed for Glenfield Blocks
A granny flat builder in Glenfield has a genuine transport draw to work with — the suburb has its own train station, and the 1970s to 1990s homes sit on 500 to 650m² blocks that mostly clear the 450m² Housing SEPP threshold for a 60m² secondary dwelling. A dwelling near the station lets easily to commuters.
The ground is highly reactive clay, so the slab is a stiffened raft engineered off a real geotech. The 1970s end of the stock can carry fibro, so where any demolition is involved a licensed asbestos strip-out leads.
Glenfield's role as a rail hub connecting Liverpool LGA to the wider network is the thing that makes a rear dwelling here reliably tenanted — you're renting proximity to a station, which always finds a tenant. I check the survey against 450m² first.

Station on the doorstep
Glenfield's own train station makes a rear dwelling reliably tenanted — you're renting proximity to rail, which always finds a commuter tenant.
Most 500 to 650m² blocks clear the 450m² Housing SEPP threshold, so a 60m² secondary dwelling is achievable via the CDC path.
Reactive clay engineering
The highly reactive clay means the slab is a stiffened raft engineered off a real geotech to suit the ground.
The 1970s stock can carry fibro, so where demolition is involved a licensed asbestos strip-out comes first.

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 Glenfield 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 Glenfield'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 Glenfield granny flat builds run on CDC fast-track where eligible. 10–15 business days to approval, 12 weeks to handover, fixed price.
