Covering Pontypridd
Our coverage around Pontypridd (CF37) also includes Tonypandy, Caerphilly and Rhondda.
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.
- Loft survey and head-height check
- New floor joists, steels and staircase
- 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 can change the price or programme?
- Head height under the ridge decides whether a conversion is practical.
- Fire safety rules can mean new fire doors on the floors below.
What happens after I enquire?
- 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.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
