Cubby & Co
Our smallest half expander — a smart, self-contained footprint available in 1 or 2 bedroom layouts.
These particular units are for properties that don't have enough space for a full expander. We designed half expanders so your granny flat vision can still come true — the same WA-engineered quality, in a smaller footprint.
