Building Granny Flats in Caddens
A granny flat in Caddens depends on the block, because this is a master-planned new-release suburb on former Western Sydney University land. It's 2010s+ contemporary homes on 300 to 500m² R2/R3 blocks with modern infrastructure and an R4 town centre at the rail-line edge. The larger lots clear the 450m² Housing SEPP threshold once the house and setbacks are counted, while the tightest don't — so the survey is the honest first step.
Where a block qualifies, the strong family demographic and WSU proximity make a studio let steadily, including to students. The town centre and Werrington station are close for tenant demand.
The soil is Wianamatta Shale grading M, so a stiffened-raft slab is engineered off a real geotech on the reactive ground. The homes are new, so asbestos usually isn't a factor.
We build fixed-price, licence HBL 487805C. Survey and soil scoped first.
Buildana manages the full granny flat process in Caddens — 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.

Master-planned blocks
Caddens is 2010s+ homes on 300 to 500m² R2/R3 blocks — the larger lots clear the 450m² Housing SEPP threshold once the house and setbacks are counted, while the tightest don't.
The survey is the honest first step, and WSU proximity makes a qualifying studio lettable, including to students.
Reactive shale
The town centre and Werrington station are close for tenant demand.
The Wianamatta Shale grading M means a stiffened-raft slab off a geotech, and the new stock rarely carries asbestos.

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 Caddens 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 Caddens'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
We build Caddens granny flats that hit the NSW 60m² maximum cleanly. Engineered slab, separate meter, rental-ready at handover.
