Quick Answer
A duplex in Padstow costs $750,000–$1,500,000+ for dual occupancy construction. Attached duplex from $750K, detached from $1M. Buildana manages feasibility, Canterbury-Bankstown Council approvals, construction and subdivision under one fixed-price contract.
Padstow Duplex Construction
A duplex in Padstow is a feasible dual-occupancy on the generous blocks that clear the Canterbury-Bankstown 600m2 minimum, with its own station. This popular family suburb runs 1950s to 1970s homes on generous blocks with strong school catchments, and at a $1.1M to $1.4M median a Torrens-title duplex on a qualifying lot is a sound play with real yield. Some lots fall short, so the area is the first check.
The ground is engineered off geotech to suit the specific lot, and on a qualifying block a side-by-side duplex works cleanly. There are no broad heritage overlays, and lots near the Georges River may carry flood planning. Where the existing home carries fibro a licensed asbestos strip-out comes first.
What I would check first on your Padstow block: whether it clears the 600m2 minimum, any flood planning near the river, and the frontage. Those set the dual-occ.
We build these fixed-price, licence HBL 487805C. Send me the block and I will tell you what dual-occupancy it carries.
Buildana manages the full duplex development process in Padstow — from feasibility assessment and architectural design through to DA or CDC approval, and fixed-price construction to dual handover. One builder, one contract, two homes.

How It Works
From First Call to Final Key
We assess your Padstow block — lot size (typical 500–700m²), width, R2 Low Density zoning, setbacks, FSR, landscaped area requirements under Canterbury-Bankstown Council's LEP and DCP. Minimum lot for duplex: 600m².
⏱Design phase covers unit layout, access, parking, private open space, and waste management for dual occupancy on your Padstow site. You approve final plans before we move to lodgement.
⏱Duplex approvals get scrutinised harder than single dwellings — neighbour notification, overshadowing, privacy, traffic, waste. Our SEE addresses each on the front foot rather than reactively.
⏱Fixed-price construction of both dwellings from slab to keys. Class M engineered footings, frame, lock-up, internal fit-out, and external works.
⏱Subdivision registration starts in parallel with final fitout so titles issue close to handover, not 6 months after. Buildana coordinates the surveyor and Canterbury-Bankstown Council clearance — important if you're planning to sell one side immediately to fund the next move.
⏱Quality Promise
Padstow dual occupancy construction: feasibility assessment first, then fixed-price build to dual handover. No surprises.
