With an ever-decreasing land availability, landowners are increasingly making the most out of their properties by replacing their old energy-inefficient homes with two new homes on that same site. A typical dual occupancy comprises two attached dwellings built over a single land allotment. Also known as a duplex, dual occupancy homes allow an owner flexible options such as living in one and renting out the other.

Construction of dual occupancy is one of the key areas of specialisation for Trusted Building Group and an excellent alternative if you are interested in property investment to maximise your equity growth.
