A duplex in Cambridge Park costs $750,000–$1,500,000+ for dual occupancy construction. Attached duplex from $750K, detached from $1M. Buildana manages feasibility, Penrith City Council approvals, construction and subdivision under one fixed-price contract.
Building Duplexes in Cambridge Park
A duplex in Cambridge Park is a feasible dual-occupancy on most blocks, because the standard lots clear the Penrith 450m2 minimum, one of Sydney's lowest. This family suburb between Kingswood and Werrington runs 1960s to 1980s fibro and brick veneer on 550 to 750m2 R2 blocks, so a Torrens-title duplex is straightforward here, with tenant demand from Western Sydney University and Nepean Hospital staff. The low minimum makes this a strong dual-occupancy market.
This is Penrith LGA, so footings are 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, which keeps the approval path predictable. Where the existing home carries fibro a licensed asbestos strip-out comes first.
What I would check first on your Cambridge Park block: the frontage for a side-by-side, the footing design, and any asbestos in the older home. 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 Cambridge Park — 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.

A clean dual-occ build
This is Penrith LGA, so footings are engineered off geotech to suit the block on both dwellings.
No broad heritage overlays keep the path predictable, with older fibro stripped under licence first.

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 Cambridge Park block against Penrith 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.
