Duplex and triplex development
Turn one block into two or three homes, with one team for the subdivision and the build.
A duplex development turns one residential block into two homes. On a larger or higher-density lot, it can be three. You might keep one to live in and sell or rent the other, or sell both.
Ways to develop
- Keep the existing home, build one new. The existing house stays on one lot and a new home goes on the other.
- Demolish and build two or three. The block is cleared and new homes are built across the lots.
- Green title or survey-strata. The type of title depends on the lot and the design; your feasibility report covers which fits.
How we work
- Feasibility report: lot options, likely costs, and a build budget for each home.
- Design with a building designer to suit the lots and your budget.
- Subdivision managed through to titles, planned around the build.
- Construction by Regional Construct on a cost-plus basis, with a realistic upfront estimate and weekly updates.
Why cost-plus
You see the real cost of every trade and material, and our fee is a fixed percentage on top. There are no hidden margins in the price, and you share in any trade savings we negotiate.
Questions
How much does a duplex cost to build in Perth?
It depends on size, finishes, site conditions and whether the existing home stays. Your feasibility report gives a ballpark build budget for your lot before you commit.
Can I live in one and sell the other?
Yes. Many owners keep one home and sell or rent the second, which can help fund the project.
