A duplex in Cranebrook 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.
Dual Occupancy Developments in Cranebrook
A duplex in Cranebrook is a feasible dual-occupancy on most blocks, because the standard lots clear the low Penrith 450m2 minimum. This established suburb north of Penrith CBD runs 1970s to 1990s brick veneer on 500 to 750m2 R2 blocks, so a Torrens-title duplex is straightforward here. The Hawkesbury-Nepean flood planning overlay affects the western edge, so a flood check leads on those lots.
The ground is Class M Wianamatta Shale on the ridge with reactive clay pockets, so footings are engineered off geotech and the slab detailed to suit on both dwellings. On a qualifying block a side-by-side works cleanly, and there are no broad heritage overlays. Where the existing home carries fibro a licensed asbestos strip-out comes first.
What I would check first on your Cranebrook block: whether it sits in the Hawkesbury-Nepean flood overlay on the western edge, the footing design for the clay pockets, 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.

Clears the low 450m2 minimum
This established suburb runs 1970s to 1990s brick veneer on 500 to 750m2 R2 blocks, so most clear the low Penrith 450m2 minimum.
A Torrens-title duplex is straightforward here, with the flood overlay on the western edge to check.
Flood and clay
The Hawkesbury-Nepean flood planning overlay affects the western edge, so a flood check leads on those lots.
The Class M shale with reactive clay pockets means footings engineered off geotech, with older fibro stripped under licence.

How It Works
From First Call to Final Key
Free feasibility check on your Cranebrook block. We measure frontage width, confirm zoning (R2 Low Density predominant), check minimum lot size against 450m² under Penrith DCP 2014 (lower than most LGAs) requirement, and review Penrith City Council's DCP controls. Written feasibility report within 5 business days.
⏱Two dwellings, one site — design is mostly about geometry. Frontage split, party wall position, garage stacking, private courtyard size, and the streetscape elevation a certifier will actually approve. We work the design until both sides feel like proper homes, not mirror-image apartments.
⏱DA through Penrith City Council (40–90 days) or CDC (10–15 business days). Cranebrook is zoned R2 Low Density predominant. Construction Certificate obtained before works commence.
⏱Dual construction runs 9–14 months. Engineered slabs sized for Class M soil, simultaneous frame-up, staggered fit-out for efficiency. Your project manager coordinates all trades and inspections.
⏱Two homes, two titles, two OCs, two warranty packs. We hand over a clean documentation set per dwelling: certifier reports, BASIX certs, structural sign-offs, appliance warranties, maintenance schedules. Whatever the next owner or buyer asks for is in the file.
⏱Quality Promise
Every Buildana duplex in Cranebrook is built under a fixed-price contract — feasibility through to dual handover and subdivision.
