St George Hospital staff keep granny flats in Penshurst full. The Kogarah medical precinct is minutes up the line, and secondary dwellings here pull $500 to $720 a week from healthcare tenants who want their own front door near a station. Penshurst has its own stop between Hurstville and Mortdale, and the demand rarely blinks.
Block sizes are the thing to verify: 400 to 600m² across the Federation, inter-war and brick-veneer streets means some lots clear the 450m² SEPP minimum easily and others miss it by metres. Georges River LEP rules are workable once the lot qualifies. Renewal is already strong on the wider streets.
What I would check first on a Penshurst block: the surveyed size against 450m², the siting, and the walk to the station. Those decide it.
We build these fixed-price, licence HBL 487805C. We will measure yours, check the overlays, and give you a genuine yes or no.
Buildana manages the full granny flat process in Penshurst — 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.

Hospital staff keep it full
St George Hospital and the Kogarah medical precinct are minutes up the line, so Penshurst secondary dwellings pull $500 to $720 a week from healthcare tenants who want their own front door near a station.
Penshurst has its own stop between Hurstville and Mortdale, and that demand rarely blinks, which makes the yield dependable.

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 Penshurst 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 Penshurst'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.
