Granny Flats Designed for Norwest Blocks
A granny flat builder being honest about Norwest has to say it plainly: this is not a granny flat suburb. Norwest is a business-park residential precinct of R3 and R4 high-density apartment towers around the Metro station, built from the 2010s. There is effectively no detached-house stock to add a secondary dwelling to, and the land economics point entirely at apartment living, not a rear-yard granny flat.
If you own an apartment here, a secondary dwelling simply does not apply. If you are looking at the area for a granny flat investment, the honest answer is that the detached stock that suits one sits in the neighbouring suburbs like Bella Vista or Baulkham Hills, not Norwest itself.
What I would check: whether you actually hold a detached freehold block anywhere near Norwest, because within the precinct itself a granny flat is not the product.
We build fixed-price, licence HBL 487805C. If you were thinking granny flat here, let me point you to the suburbs where it actually works.
Buildana manages the full granny flat process in Norwest — 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.

Why a granny flat does not fit Norwest
Norwest was master-planned as a high-density apartment and business-park precinct around the Metro station, and R3 and R4 zoning dominates. A granny flat is a rear-yard secondary dwelling on a detached-house block, and that stock effectively does not exist here. So on almost any Norwest parcel, a secondary dwelling is not the product, and I would rather tell you that than sell you a feasibility with no path.
If you own an apartment in Norwest, a secondary dwelling does not apply at all. The land here is about apartment living and the business park, not backyard granny flats.
Where it does work nearby
If your goal is a granny flat investment in the Hills, the detached stock that suits one sits in the neighbouring suburbs: Bella Vista, Baulkham Hills, Kellyville and Castle Hill all have the generous detached blocks a secondary dwelling needs. I would rather point you at a suburb where the numbers actually work than build the wrong product in Norwest. If you hold a block in one of those, I can run the granny flat feasibility there.

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 Norwest 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 Norwest'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
