Covering Bridgend
Our coverage around Bridgend (CF31) also includes Porthcawl, Cowbridge and Llantwit Major.
Homes in Mid Glamorgan
Welsh homes include long terraces built into hillsides, stone cottages and modern estates, and sloping sites often shape how and where an extension can go.
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
- Design drawings and structural calculations
- Dormer or rooflights, insulation and plasterboard
How much should I budget for a loft conversion?
What loft conversions typically cost. These are guide ranges; the written quote for your house replaces them.
| 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 |
What approvals does a loft conversion need in Wales?
In Wales the planning rules, including what counts as permitted development, are set by the Welsh Government, and Welsh building regulations differ in places from England’s. We check both against your house before drawings are finalised, and handle party wall notices where needed.
Wales has its own loft and roof permitted development rules.
What should I think about before starting?
- Fire safety rules can mean new fire doors on the floors below.
- Party wall notices are often needed for steels bearing on a shared wall.

Your questions answered
How much does a loft conversion cost?
Roughly £30,000 to £45,000 for a rooflight conversion, £50,000 to £90,000 for a dormer, £60,000 to £95,000 for a hip-to-gable and £65,000 to £110,000 for a mansard, including VAT.
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.
Can you visit a house in Bridgend to quote?
Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
