Sydney & NSW · fixed price · CDC handled
Granny flat builders in Sydney.
Fixed price. Built in 8 weeks. Approvals sorted.
A granny flat that pays for itself, without the wait.
Most Sydney granny flats take 4–6 months and hide their real price behind a “from” figure. We publish three fixed prices, itemise every inclusion, handle the CDC approval, and hand over a complete secondary dwelling in 8 weeks — built off-site while your backyard is prepared.
Build it for parents or adult kids today, or rent it out — a backyard granny flat is the rare investment that adds income without buying more land.
Three granny flat designs, fixed price.
Each is a proven floor plan with a published price — a 1-bedroom studio, a 2-bedroom at the 60 m² secondary-dwelling limit, and a larger 2-bath option. Tap any design for the full floor plan and specs.

Cost breakdown & calculator ↗Granny flat approval in NSW, the fast way.
Most granny flats skip council entirely via Complying Development. Here's what your block needs — and read the full guides in our journal.
450 m² & 12 m wide
The block must be a residential zone, at least 450 m² with 12 m of width at the building line.
Up to 60 m²
A secondary dwelling capped at 60 m² keeps the fast CDC pathway open — no full council DA.
CDC in ~10 days
A private certifier assesses against a fixed checklist — approval in as little as 10 business days.
We lodge it
We prepare plans, check setbacks and easements, and lodge the CDC for you.
Family now, income later.
