Triplex Developments Perth

As a general rule, adding more units into a development has a multiplier effect on potential returns. Adding too many units can increase risks and costs. For those reasons, triplex developments are often viewed as the best type of development to maximize your returns. On one block, triplex developments generally have three single or double storey homes around a shared driveway.

Advantages of Triplex Developments

• Demolishing and building provides more configuration options than a house-behind-house development.
• Modern, low-maintenance homes are easier to sell or rent out.
• Selling or renting one or all homes provides huge cash flow opportunities.
