Dual Occupancy
Build More From Your Block
Whether you're planning for your family, generating rental income, or getting the most out of your land, dual occupancy lets you build more than one home on a single block.
The Bourne Group delivers two proven paths: a full duplex or a self-contained granny flat, each designed, engineered and built to the same standard as every custom home we hand over.
The Duplex
Two full homes, side by side.
A duplex gives you two independent, full-sized dwellings on the one block, ideal for multi-generational living, rental income from both sides, or selling one to help offset your build cost. Each home gets its own street presence, private entry and layout, so neither feels like an afterthought.
Full-size 3-4 bedroom living on both sides
Seperate driveways, entries and yards
Option to subdivide onto seperate titles
Strong rental and resale return potential


The Granny Flat
A self-contained second home, in your backyard.
A granny flat (secondary dwelling) adds a fully self-contained home to your existing property, perfect for ageing parents, adult kids, a home office, or a private rental. Built to the same quality as our main residences, just on a smaller footprint and a faster timeline.
1-2 bedroom living
Faster approvals and shorter build time
Keeps family close on one property
Popular, low-effort passive rental income
