Bungalow and upward extensions in Cardigan

Homes in Dyfed

Welsh homes include long terraces built into hillsides, stone cottages and modern estates, and sloping sites often shape how and where an extension can go.

What goes into an upward extension?

An upward extension adds a new storey on top of an existing house, most often turning a bungalow into a two-storey or chalet-style home. It can double the floor area without using any of the garden.

Do you need permission for an upward extension in Cardigan?

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.

Adding a storey in Wales needs planning permission. We prepare the application with drawings showing how the new roofline fits the street.
