Covering Ystalyfera

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.
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.
- Planning and building regulations checks under Welsh rules
- Staircase and changes to the ground floor layout
- Full fit-out of the new rooms

Do you need permission for an upward extension in Ystalyfera?
Planning decisions in Wales are made by the local council, using permitted development rules set by the Welsh Government rather than England’s. Building regulations in Wales have their own approved documents, and the Party Wall etc. Act 1996 applies to work on shared walls and boundaries.
Adding a storey in Wales needs planning permission. We prepare the application with drawings showing how the new roofline fits the street.
What should I think about before starting?
- The staircase takes space from the ground floor plan.
- The house is exposed while the roof is off, so the sequence is planned tightly.
