A Dual Key is a single residential property on one title designed as two separate, self-contained dwellings under one roof, usually featuring a main house (e.g., 3-4 bedrooms) and a smaller unit (e.g., 1-2 bedrooms)
This layout can accommodate two households on one legal title. Each area in the dwelling may have its own entrance allowing occupants to live in or rent each area independently and share facilities such as a laundry area.
They are often designed to look like normal houses from the street but have a separate door on the side.
A dual key property is different from a dual occupancy or duplex, which often means two self-contained dwellings, whether or not attached, for separate households on one legal title.
Our builders have a wide range of dual key designs to choose from.
Versitility
Perfect for extended family, teenage retreats, or separated living arrangements while maintaining privacy
Dual Income
Investors can rent both sides independently, often yielding higher returns (6-7%) than standard homes.
Flexibility
Ideal for “house hacking” where owners live in one side and rent out the other to pay down the mortgage.
