A duplex in Norwest is not really the product, because this is a business-park residential precinct of R3 and R4 high-density apartments around the Metro station, not a detached dual-occupancy market. The suburb is apartment-led, with 2010s-onwards towers replacing the former low-density fringe, so a Torrens-title duplex on a freestanding lot is very unlikely. I would rather be straight about that than pretend otherwise.
The Norwest Business Park employment hub and the Metro station drive the density framework, so splitting a block does not fit. The ground is Wianamatta Shale, engineered off geotech. If you are after dual-occupancy yield, neighbouring Bella Vista or Baulkham Hills with genuine R2 lots make far more sense, and I will point you to them.
What I would check first at Norwest: whether any freestanding duplex-capable lot exists at all, which is very unlikely, and the better dual-occ options nearby. That is the honest starting point.
We build these fixed-price, licence HBL 487805C. Tell me what you are after and I will point you to where a duplex actually works.

An apartment-led precinct
This business-park precinct runs R3 and R4 high-density apartments around the Metro station, with 2010s-onwards towers.
The apartment-led framework makes a Torrens-title duplex on a freestanding lot very unlikely.
Honest redirect
The ground is Wianamatta Shale engineered off geotech, but a duplex splitting a block does not fit the density framework.
For dual-occupancy yield, neighbouring Bella Vista or Baulkham Hills with genuine R2 lots make far more sense.
