What is a duplex or dual occupancy house?

Dual occupancy or duplex house designs may be just what you’re looking for. A duplex is two homes on one property which can be subdivided at completion. In Australia, they must be over 60m2 in area. Duplex designs are ideal for retirees or couples who don’t have children. Duplexes mean no Body Corporate to keep happy and no strata fees to worry about. They are simply smaller, more manageable home units that may suit your changing lifestyle.


What is a secondary house or granny flat?

A secondary house or granny flat is not over 60m2 in area and cannot be subdivided when completed. Our Home Designs has some suitable house concept plans you may like to purchase.
