Homes in Mid Glamorgan
Housing in Wales ranges from terraced streets in the valleys and older industrial towns to stone-built homes in rural areas and modern estates around the cities.
What does an upward extension involve?
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.
- Roof removal and temporary weather protection
- New first-floor structure, walls and roof
- Staircase and changes to the ground floor layout

Welsh projects need planning clearance from the council under Welsh rules, building regulations approval under the Welsh approved documents, and party wall notices where the work affects a neighbour’s wall or foundations.
Adding a storey in Wales needs planning permission. We prepare the application with drawings showing how the new roofline fits the street.
What should Porthcawl homeowners check first?
- The staircase takes space from the ground floor plan.
