Development

Specialist property development and unit developers in Perth.

Westlay Homes Developments are specialist property and unit developers based in Perth. We help landowners turn their property into a fast, profitable and well-managed development across Perth and Western Australia.

Whether you already own land or are looking for a block with strong development potential, our team can guide you from the very first idea through to completion. Having developed a wide range of sites across Perth, we can advise on the best way to unlock your land's value — be it a duplex, triplex, multi-unit development or a house-behind-house build.

House Behind House

House Behind House

More and more Perth property owners are recognising that their backyard is an untapped investment. By building a second home behind the existing one, you can rent out the new property for an ongoing income, or build your dream home at the rear and rent or sell the original. It's a smart way to make a large block work harder for you.

Benefits of House-Behind-House Developments
  • Unlock the unused value in your larger block.
  • In many cases you can continue living on site while the development progresses.
  • Renting or selling one or both homes creates significant cash-flow opportunities.
Typical House-Behind-House Layouts
While the layout shown is typical of house-behind-house developments, Westlay Homes approaches every site individually to unlock the best possible land value and maximise your returns. Let us take the complexity off your hands — we deliver a seamless service from planning through to completion.
R-Code Check
The quickest way to check whether your property is eligible for subdivision is to find out its Residential Planning Code (R-Code) — your local council can supply this. As a general guide, the figures below apply to a house-behind-house development.

Duplex

Duplex

Relatively straightforward compared with other development styles, side-by-side duplex developments are extremely popular with first-time developers. Typically an older home is demolished to make way for two modern, low-maintenance homes of similar size. Keep one and sell the other, rent them both, or sell both — whatever your plan, the potential return on investment is excellent.

Benefits of Duplex Developments
  • Unlock the unused value in your larger block.
  • Demolishing and rebuilding offers more design flexibility than a house-behind-house development.
  • Subdivision and final approvals are comparatively easier to obtain.
  • Modern, low-maintenance homes are easier to sell or rent out.
  • Selling or renting one or both homes creates significant cash-flow opportunities.

Triplex

Triplex

As a general rule, adding more units to a development has a multiplier effect on potential returns — but too many units can also increase risk and cost. For that reason, triplex developments are often seen as the sweet spot for maximising returns. On a single block, a triplex typically features three single or double-storey homes arranged around a shared driveway.

Benefits of Triplex Developments
  • A multiplier effect on potential returns without over-complicating the development.
  • Demolishing and rebuilding offers more design flexibility than a house-behind-house development.
  • Modern, low-maintenance homes are easier to sell or rent out.
  • Selling or renting one or all homes creates significant cash-flow opportunities.

Multi-Unit Development

Multi-Unit Development

Multi-unit developments make the most of your land by dividing a large block into several medium or high-density dwellings. These can include houses, townhouses, apartments and other units, and often share common facilities such as parking areas or security.

Benefits of Multi-Unit Developments
  • Greater returns on offer.
  • Demolishing and rebuilding offers more design flexibility than a house-behind-house development.
  • Modern, low-maintenance homes are easier to sell or rent out.
  • Selling or renting one or all homes creates significant cash-flow opportunities.
