Expandify homes are designed and certified as Class 1a dwellings.

If you want to use the space as a retail shop, studio, gallery, or commercial premises, this will need to be approved by your local council. Some councils may allow this with:

A change of building class

Public access compliance (disability access, egress)

Commercial overlay approval

Expandify does not change the building classification but can supply supporting documentation. You will need to work with a private certifier or town planner to confirm approval.
