A granny flat builder in Mays Hill works with a small pocket between Parramatta and Merrylands — the established homes sit on 450 to 650m² blocks that mostly clear the 450m² Housing SEPP threshold for a 60m² secondary dwelling. Proximity to Parramatta CBD drives strong demand for a rear dwelling, whether you let it or house family.
The ground is moderately reactive, so the slab is engineered off a real geotech to suit — a proper footing calibrated to the actual soil. The older stock can carry fibro, so a licensed asbestos strip-out leads where any demolition is involved.
Westmead station sits about a kilometre out, adding to the tenant pool alongside the Parramatta workforce. The blocks sit around 450m² at the lower end, so the survey decides it — I check yours against the line first.

Parramatta on the doorstep
Mays Hill's spot between Parramatta and Merrylands drives strong demand — proximity to Parramatta CBD and Westmead means a rear dwelling never wants for tenants.
The 450 to 650m² blocks mostly clear the 450m² Housing SEPP threshold, though the lower end sits close to the line, so I check the survey first.
Established stock, moderate clay
The moderately reactive ground means the slab is engineered off a real geotech to suit — calibrated to the actual soil.
The older stock can carry fibro, so a licensed asbestos strip-out leads where demolition is involved.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. Free on-site assessment of your Mays Hill property. We measure setbacks, check existing services, assess access, and confirm your 450–650m² block meets Cumberland City Council's requirements for a secondary dwelling. 60m² sounds tight on paper but designs well — high ceilings, good cross-ventilation, smart storage, and proper bedroom proportions make a 2-bed feel generous. We design for daily liveability, not just floor plan compliance.
⏱The Mays Hill construction phase. Fixed price, programmed, supervised. CDC fast-track through a private certifier — typically approved in 10–15 business days. Mays Hill is zoned R2 Low Density & R3 Medium Density. Construction Certificate issued before works start. Your granny flat is built from slab to keys in a single programme. Engineered slab for Class M soil, frame, lock-up, fit-out, painting, flooring, and external works. Quality inspections at every stage.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Defect-free inspection means we don't hand over a list to chase — every snag is fixed before keys move. Final clean, electrical and plumbing tested, smoke alarms certified, BASIX commissioning verified. The unit is rental-ready, not project-paperwork-ready.
