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.
- Planning and building regulations checks under Welsh rules
- Structural survey of walls and foundations
- Full fit-out of the new rooms

Planning and building rules in Haverfordwest
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 Haverfordwest homeowners check first?
- The staircase takes space from the ground floor plan.
- The house is exposed while the roof is off, so the sequence is planned tightly.
How does the project run?
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
