Homes in West 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 is a loft conversion?
A loft conversion turns an unused roof space into habitable rooms, usually a bedroom with an en-suite, by strengthening the floor, adding a staircase, insulating the roof and putting in windows. The type you need depends on the roof: rooflight, dormer, hip-to-gable or mansard.
- Planning and building regulations checks under Welsh rules
- Dormer or rooflights, insulation and plasterboard
- En-suite, electrics, heating and fire safety upgrades

Do you need permission for a loft conversion in West Glamorgan?
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.
Wales has its own loft and roof permitted development rules. Rear dormers within set volume limits are often allowed, but the detail differs from England's, so we confirm the current Welsh limits against your roof before the design is fixed.
What can affect a loft conversion?
- Head height under the ridge decides whether a conversion is practical.
- Party wall notices are often needed for steels bearing on a shared wall.

What people ask before starting
How long does a loft conversion take?
Usually 6 to 14 weeks on site depending on the type.
Do I need fire doors?
Often yes. Building regulations require a protected escape route from the new floor, which usually means fire doors on to the stairs and linked smoke alarms.
How do I get a price for loft conversions in West Glamorgan?
Use the guide price tool for a ballpark figure, then book a visit for a fixed written price for the agreed specification.
