A duplex in West Hoxton 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.
Building Duplexes in West Hoxton
A duplex in West Hoxton works on the blocks that clear the Liverpool 600m2 minimum, and the newer stock makes the build straightforward. The suburb runs 1990s to 2000s homes on 500 to 650m2 R2 lots, so the larger ones qualify and the tighter estate blocks fall short. On a $900K to $1.1M market with M7 access, a Torrens-title duplex on a qualifying lot is a sound family or investor play.
The ground is highly reactive clay, so footings are engineered off geotech and the slab detailed to suit on both dwellings. The bonus with 1990s to 2000s stock is the demolition, which is past the asbestos era, so a strip-out is rarely needed. A side-by-side sits cleanly once the frontage checks out.
What I would check first on your West Hoxton block: the area against 600m2 and the frontage, because the estate lots vary more than they look.
We build these fixed-price, licence HBL 487805C. Send me the block and I will tell you what it carries.
Buildana manages the full duplex development process in West Hoxton — 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.

Estate lots against 600m2
West Hoxton lots run 500 to 650m2, so the larger ones clear the Liverpool 600m2 minimum and the tighter estate blocks fall short.
M7 access and family amenity give a completed duplex steady demand at the $900K to $1.1M market.
Reactive clay, clean demolition
The highly reactive clay means footings engineered off geotech and the slab detailed to suit on both dwellings.
Being 1990s to 2000s stock, the homes are past the asbestos era, so demolition is usually clean.

How It Works
From First Call to Final Key
Site visit, title search, and planning assessment for your West Hoxton block. We check lot dimensions against Liverpool City Council's minimum (600m²), review overlays, drainage, access, and services. You get a clear yes/no on duplex feasibility plus estimated yield.
⏱Design has to satisfy four audiences at once: Liverpool City Council, the future buyer or tenant, the certifier, and you. Each pull in a different direction — our job is to land plans that work for all four. Solar access, privacy, parking, POS, FSR, all balanced.
⏱We lodge and chase your approval — DA through Liverpool City Council for most duplexes, or CDC where eligible. R2 Low Density zoning in West Hoxton. CC issued, conditions cleared, ready to build.
⏱Building both sides in parallel halves the loan interest holding cost vs sequential builds. Bulk material orders for cabinetry, tiles, fixtures cut unit cost. Single site setup, single supervisor, single insurance period — efficiency compounds across the whole programme.
⏱Strata or Torrens title subdivision completed. Separate OCs, individual metering, 6-year structural warranty per dwelling. Strong rental demand near Liverpool (5 km).
