A duplex in Sydney Olympic Park does not fit the precinct, and I will be straight about it. This is a master-planned event and residential precinct on the former Homebush Bay industrial site, built from the 2000s as R4 high-rise towers with no detached stock. There are no standard house blocks to build a duplex on, so dual occupancy simply is not the product here.
The ground is Wianamatta Shale and reclaimed alluvial soil, with heavy industrial-legacy contamination management on remediated parcels, so any build is a serviced high-density project engineered to suit, not a suburban duplex. The Sydney Metro West station precinct is reinforcing that high-density direction.
What I would check first, honestly, is whether you actually have a detached lot here at all, because the precinct is apartments, not duplex land.
We build these fixed-price, licence HBL 487805C. If you have a block anywhere nearby with detached zoning, send it and I will tell you honestly what it can carry.
Buildana manages the full duplex development process in Sydney Olympic 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.

There are no standard house blocks for a duplex, so dual occupancy is not the product here.
Reclaimed ground, high-density direction
Wianamatta Shale and reclaimed alluvial soil with heavy contamination management make any build a serviced high-density project.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. Free feasibility check on your Sydney Olympic Park block. We measure frontage width, confirm zoning (R2 Low), check minimum lot size against 600m² (R2) under Parramatta DCP 2023 requirement, and review City of Parramatta 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.
⏱The Sydney Olympic Park construction phase. Fixed price, programmed, supervised. DA through City of Parramatta Council (40–90 days) or CDC (10–15 business days). Sydney Olympic Park is zoned R2 Low. 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.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. 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.
