A duplex in Edmondson Park costs $750,000–$1,500,000+ for dual occupancy construction. Attached duplex from $750K, detached from $1M. Buildana manages feasibility, Liverpool City Council approvals, construction and subdivision under one fixed-price contract.
Edmondson Park Duplex Construction
A duplex in Edmondson Park benefits from a low dual-occupancy minimum. This master-planned growth suburb sits on 300 to 450m² lots, and with Liverpool's 400m² dual-occupancy threshold on the relevant land, many of these compact blocks clear it, so a Torrens-title duplex at an $850K to $1.1M median suits the strong young-family and investor demand around the station and Ed Square.
This is Liverpool LGA on reactive clay, so the duplex slab and footings are engineered to suit the ground from the outset, designed off geotech. The compact lots reward an efficient duplex design with good orientation, and R3 zoning on parts of the precinct can open a higher-density yield on the right block worth checking.
What I would check first on your Edmondson Park block: whether it clears the 400m² dual-occupancy minimum or sits in an R3 pocket, and the reactive-clay footing design. Those decide the play.

How It Works
From First Call to Final Key
Quick desktop check first — lot size, zoning, frontage — then full site visit if it stacks. Drainage path, neighbour overlooking, slope, services, easements. 400m² minimum is just the entry ticket; the real feasibility is whether two compliant dwellings actually fit and sell.
⏱Our architect designs both dwellings to maximise your Edmondson Park block's yield — floor plans, elevations, 3D renders, and landscape concept. We optimise for rental return and sale value under Liverpool City Council's DCP.
⏱Most Edmondson Park duplexes go DA route through Liverpool City Council — CDC pathways for dual occupancy are restrictive on most R2 blocks. We pre-meet with council planners on borderline sites to confirm support before lodgement, which avoids a 3-month round trip on RFIs.
⏱Both dwellings built simultaneously — engineered slabs (Class H–E soil), frame, lock-up, fit-out. Milestone updates from your project manager.
⏱Final inspections, dual OCs issued, subdivision registered with LRS. Each dwelling gets its own title, services, and 6-year structural warranty. Ready to rent, sell, or occupy.
