A granny flat in Greenacre costs $150,000–$300,000+ depending on size and finishes. 1-bed from $150K, 2-bed from $200K. CDC fast-track approval in 10–15 business days. Buildana manages design, Canterbury-Bankstown Council approval and fixed-price construction.
Greenacre Secondary Dwellings
A granny flat builder in Greenacre works with wide residential blocks that make the model easy. The fibro and brick stock sits on generous 550 to 800m² lots that clear the 450m² threshold for a 60m² secondary dwelling under the Housing SEPP with room to spare, and the strong extended-family culture plus proximity to Bankstown drive steady demand for a rear-yard dwelling.
The ground is moderately reactive clay, so the slab is engineered off geotech to suit. The 1950s to 1970s stock often carries fibro, so a licensed asbestos strip-out comes first where demolition is involved. The wide lots give plenty of room for separate access and private open space.
What I check first on your Greenacre block: whether the survey confirms the area — most clear 450m² easily — the rear-yard access and setbacks, and the slab off geotech.

Wide blocks, easy feasibility
Greenacre's generous 550 to 800m² lots clear the 450m² Housing SEPP threshold with room to spare, so a 60m² secondary dwelling is achievable on nearly every block.
The extended-family culture and proximity to Bankstown drive steady demand for a rear-yard dwelling, and the wide lots leave plenty of room for separate access and private open space.
Reactive clay and fibro
The moderately reactive clay means the slab is engineered off geotech to suit.
The 1950s to 1970s stock often carries 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 Greenacre property. We measure setbacks, check existing services, assess access, and confirm your 550–800m² block meets Canterbury-Bankstown 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 Greenacre construction phase. Fixed price, programmed, supervised. CDC fast-track through a private certifier — typically approved in 10–15 business days. Greenacre is zoned R2 Low 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.
⏱Quality Promise
Every Buildana granny flat in Greenacre is built under a fixed-price contract with full Greenacre council compliance and a 6-year structural warranty.
