Gledswood Hills Secondary Dwellings
Gledswood Hills is a premium master-planned new-release suburb — 350 to 550m² blocks, contemporary homes from the 2010s, strong amenities and a family-heavy demographic. Granny flats work on the larger blocks here, but the newer, tighter lots mean block size does a lot of the deciding.
On the blocks up near 550m² there's usually room for a proper second dwelling. On the tighter ones nearer 350m², once you count the modern house, setbacks and separation, the space left can be marginal — so I lean on the survey rather than a hopeful sketch.
The ground is Wianamatta Shale, reactive, so the slab is engineered off a geotech. Nothing unusual for the corridor, just done properly.
Fixed price, survey-led on the tight blocks. Licence HBL 487805C.

Block size does the talking
On the larger Gledswood Hills blocks near 550m², a second dwelling fits comfortably with its own yard. On the tighter 350m² lots, the modern house already takes a big share, and once setbacks and separation are added, the space left can be marginal.
I won't promise a layout on a tight block sight unseen. I get the survey, work out what genuinely fits, and tell you honestly whether it's a clean one-bedroom, a compact build, or not quite worth it.
Straightforward ground, family market
The Wianamatta Shale is reactive, so the slab is stiffened and designed off a geotech report. That's the technical must-do here, and getting it right first keeps the fixed price stable.
This is a family suburb with good amenities, so a flat suits either a rental or accommodation for relatives. I build to match the newer homes around it rather than dropping a cheap box in the yard.
