Double the potential of your block with a duplex

If the existing property on your block isn’t sufficient, demolishing it to make way for a duplex development is a popular and simple development decision.

If your block is zoned at R20 to R40, a duplex home is a viable option.

Generally speaking, doubling the properties on the one block increases equity, and can provide a source of income and tax benefits. You can sell the duplexes for profit, live in one and sell the other, rent each duplex home for an income stream, or perhaps you want to build separation accommodation for family.

Our expert Development Consultants can help you select from a range of duplex designs which is best for your block and budget.
