A duplex in Bradbury costs $750,000–$1,500,000+ for dual occupancy construction. Attached duplex from $750K, detached from $1M. Buildana manages feasibility, Campbelltown City Council approvals, construction and subdivision under one fixed-price contract.
Dual Occupancy Developments in Bradbury
A duplex in Bradbury benefits from one of the lower dual-occupancy minimums in Sydney. Campbelltown's DCP sets 500m², so most of the 500 to 750m² brick-veneer blocks here clear it comfortably, and a Torrens-title duplex at an $850K to $1.1M median delivers two affordable dwellings with strong yield. Campbelltown Hospital staff drive steady rental demand for exactly this kind of stock.
The ground generally behaves, so the duplex slab and footings off geotech stay predictable, and where older homes carry fibro a licensed asbestos strip-out comes first. A compliant duplex on a clearing block moves through Campbelltown Council on a predictable path, and the hospital and shopping-centre amenity keeps demand solid.
What I would check first on your Bradbury block: whether it clears the 500m² minimum, the slab off geotech, and any asbestos before demolition. Those set the feasibility.

How It Works
From First Call to Final Key
A duplex is really a feasibility problem wearing a construction outfit. Before anything else, we verify your Bradbury block against Campbelltown City Council's LEP — lot size, frontage, FSR, landscape area. If it doesn't stack up, you find out in a week, not after 3 months of design.
⏱Design runs dual from day one. Two dwellings, one coherent streetscape, party-wall acoustics and fire rating built into the structure rather than bolted on. The plan accommodates R2 Low Density predominant zoning without looking like two mismatched houses sharing a fence.
⏱Approval and construction get sequenced together. Slab pours are choreographed so the trades show up once, frame up both sides, and keep rolling. Two separate meters, two separate services, but one crew, one programme.
⏱Handover is dual. Both dwellings walked at the same time, both OCs in the same issue, both titles subdivided before settlement. You leave the final inspection with the option to live in one and rent the other, or to sell both.
⏱Quality Promise
We build duplexes in Bradbury end-to-end — feasibility, design, DA/CDC, dual-slab construction, subdivision. One contract.
