Duplexes Sydney

For about half the price of a conventional home, you can build a duplex and share the accommodation with another family or group of guests – without having to settle for a shared living space either. Our duplexes accommodate for occupants on each side, by incorporating spacious living arrangements that combine all the comforts of home under one roof. For a Duplex Builder Forster that understands the complex and intricate design of duplex properties – AusHomes Builders bring the experts straight to you.Duplex designs consist of two separate dwellings that can cater to two different households shared by a common wall. Whether you rent both properties or live in one and rent the other, the choice is yours!

Personalised Duplexes

Our home designers take into consideration the living requirements of all occupants, by offering a diverse range of floor plans and specifications. We take you through the entire planning process, and combine ergonomic design choices with aesthetic appeal for the most appealing living solutions.

Each duplex is personalised for both sides of the property with aspects such as room size, entertainment and kitchen arrangements allocated to the most ideal locations.


The benefits of building a duplex as opposed to a traditional single home include the ability to generate two rental incomes from the one block of land, the added flexibility for living arrangements (occupy both, rent one, live in one) and a greater return on investment.
