Duplex plans put two homes on one block, a smart way to add value to a site, house extended family or generate rental income. Browse duplex and dual occupancy designs reviewed so both homes can have north facing living areas.
Dual occupancy works best when the design respects orientation and the block, and in NSW the Housing SEPP now permits it in most residential zones. Search by your site width and depth, set your driveway side, and see the duplex plans that fit.
This page lists 60 plans, from builders including Masterton Homes, Vision Homes, Allworth Homes, Meridian Homes, priced from $486k to $508k, from builders rated 3.0 to 4.9 on Google.
Architect reviewed for real Australian blocks
Dudils checks each approved plan for the direction its living areas need to face, the block envelope it fits, and whether the garage or driveway placement supports passive solar design. It is a shortlist for better conversations with your builder, designer or architect.

Summer: eaves block sun
Winter: lower angle lets sun in
In winter the low northern sun streams through north facing windows for free heat. In summer a roof overhang blocks the high sun. Good orientation cuts your energy bills with no mechanical systems.

Questions about duplex plans
What makes these duplex plans different?
Dudils lists plans that have been reviewed for north facing living areas, block fit and practical orientation, rather than simply repeating a builder catalogue category.
Does north need to be at the backyard?
No. A good plan can work whether north falls to the backyard, the street or either side, as long as the main living areas and glazing are arranged to collect northern light.
Should I still check this with my builder or designer?
Yes. Dudils helps you shortlist better oriented plans, but final siting, setbacks, window changes and energy compliance should be confirmed with your builder, designer or architect.
