We are expert duplex builders in Sydney and know
the ins-and-outs of building duplexes in your area.



What is a duplex?

A duplex is a property which consists of two independent homes sharing a common wall. Duplex designs can offer multiple benefits and are also a great investment. Not only are duplexes more affordable than building a house, but there is an option to live in one and rent out the other or rent out both units to diversify your revenue.

A duplex home is also convenient for those with larger families or those catering for other family members such as grandparents or even married children struggling to afford their own property in the expensive housing market. A duplex home offers privacy, independence and the convenience of being next door to another relative. If you have a family member who requires care or supervision, a duplex home is a great housing option to achieve these responsibilities whilst maintaining your own privacy.

Is building a duplex a good investment?

Since the surge of the Australian housing market prices, duplex homes have become one of the most popular ways to deal with housing affordability across Sydney. Their return on investment has proven to be generous, with many property owners selling the second half of their property. Other homeowners have utilised duplexes as a source income by renting their property. This rental income can significantly reduce the financial strain of mortgage repayments and even serve as an extra investment.

What is the cost of building a duplex in Sydney?

Building a duplex may cost more than building a single house of the same size but it remains still less expensive that building two houses. Building two dwellings on the same block of land helps maintain lower land costs as opposed to two separate blocks.
The financing planning that goes into developing a duplex is very different to buying an investment property, so it’s important to work with specialists to talk you through all the potential costs involved.
