A dual occupancy home is a smart solution for homeowners and investors who want to create two dwellings on one lot without purchasing additional land. It can offer flexibility for multi-generational living, added rental income and stronger long-term value from a single property.

Perry Homes can help you choose a dual occupancy design that aligns with your land and intended use.
