Homes in Powys
Across Wales you find valley terraces, coastal towns, rural stone houses and newer estates, so access, slopes and local materials all feature in the design.

Do you need permission for a garden annexe in Builth Wells?

In Wales an annexe with sleeping accommodation needs planning permission, usually with a condition tying it to the main house.
What should Builth Wells homeowners check first?
- The annexe normally has to remain part of the main household, not let as a separate home.
- Drainage may need a pump if the garden falls away from the sewer.
