Homes in West Glamorgan
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 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
How much should I budget for a loft conversion?
Use these ranges to budget for loft conversions; the survey turns them into a fixed price for the agreed specification.
| Loft conversions | Guide price incl. VAT |
|---|---|
| Rooflight conversion | £30,000 to £45,000 |
| Dormer conversion | £50,000 to £90,000 |
| Hip-to-gable with dormer | £60,000 to £95,000 |
| Mansard conversion | £65,000 to £110,000 |
Do you need permission for a loft conversion in Swansea?
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.
- The new staircase usually takes space from the landing or a bedroom below.
What are the steps?
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
Your questions answered
Is my loft suitable for conversion?
If there is about 2.2 m or more from the top of the ceiling joists to the underside of the ridge, it usually is. We check this at the free site visit.
Can we live at home during a loft conversion?
Yes. Most of the work is done from scaffolding until the staircase goes in near the end.
Do you work in Swansea?
Yes. Swansea is within our coverage for loft conversions, along with nearby Neath and Pontarddulais.
