In Perth’s commercial and events scene, the terms defit and fitout get tossed around a lot—but they describe two completely different phases of a space’s lifecycle. Builders, developers, and property managers who understand how each works save serious time and money when projects change hands.

A fitout transforms an empty shell into a functional, branded environment. A defit, on the other hand, strips it all back to base condition. Both demand planning, permits, and the right contractor. Skip either, and you risk costly overruns, delays, or penalties when leases end.
