Duplex Builder Milperra — From $750K Fixed Price
Fixed-price duplex construction in Milperra 2214. Two dwellings, one contract, no variations. Minimum lot 600m². Free feasibility.
Building Duplexes in Milperra
A duplex in Milperra is a feasible dual-occupancy on the lots that clear the Canterbury-Bankstown 600m2 minimum. This suburb mixes residential areas with the former Western Sydney University campus, and the established homes on standard blocks offer renewal, so a Torrens-title duplex on a qualifying lot is a sound play at a $1.0M to $1.25M median. Some standard 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. Lots near the Georges River may carry flood planning, so that check leads on low-lying streets. Where the existing home carries fibro a licensed asbestos strip-out comes first.
What I would check first on your Milperra 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.
