Covering Weymouth
We work in Weymouth (DT3, DT4) and the places around it, including Dorchester, Bridport and Poole.
Homes in the South West
Homes in the South West range from coastal and rural properties in stone and slate to city terraces and modern estates, so extensions are designed to match the local materials.
What is included in a loft conversion in Weymouth?
We start with the head height. You need roughly 2.2 m or more from the top of the ceiling joists to the underside of the ridge for a conversion to work without raising the roof. From there we design the staircase position, the type of conversion and the en-suite, and manage the whole build including fire safety and building control.
- Loft survey and head-height check
- New floor joists, steels and staircase
- En-suite, electrics, heating and fire safety upgrades
What will a loft conversion cost?
Typical ranges for loft conversions. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.
| 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 |
How is a loft conversion approved in Weymouth?
English projects need planning clearance from the local council, building regulations sign-off from building control, and party wall notices where the work is on or near a shared boundary. We prepare and manage all three.
In England many loft conversions are permitted development: the extra roof volume must stay within 40 m³ on a terraced house or 50 m³ on a semi or detached house, nothing can sit higher than the existing ridge, no dormer can face a road on the main elevation, and side windows must be obscure-glazed and non-opening below 1.7 m. Houses in conservation areas, National Parks and National Landscapes cannot use these roof-extension rights, so dormers there need planning permission (a rooflight-only conversion can still be permitted development), and flats always need permission.
What should I think about before starting?
- The new staircase usually takes space from the landing or a bedroom below.
- Party wall notices are often needed for steels bearing on a shared wall.
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.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
What people ask before starting
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.
Can you visit a house in Weymouth 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.
