What do you get with a garden annexe?

A garden annexe is a separate single-storey building in the grounds of a house with its own bedroom, bathroom and kitchenette, used by family members as part of the main household. Unlike a garden office, an annexe that people sleep in normally needs planning permission and full building regulations approval.

How is a garden annexe approved in Aberystwyth?

In Wales the planning rules, including what counts as permitted development, are set by the Welsh Government, and Welsh building regulations differ in places from England’s. We check both against your house before drawings are finalised, and handle party wall notices where needed.

In Wales an annexe with sleeping accommodation needs planning permission, usually with a condition tying it to the main house.

What should I think about before starting?

The annexe normally has to remain part of the main household, not let as a separate home.
A level threshold and wider doors make the annexe suitable for later life.
