Covering St Albans
We work in St Albans (AL1, AL3) and the places around it, including Harpenden, Hatfield and Hemel Hempstead.
Homes in the East of England
The East of England has a large stock of post-war and modern estate housing alongside period homes in market towns, which makes garage conversions, single-storey extensions and loft conversions popular.
What is included in a hip-to-gable loft conversion in St Albans?
Hipped roofs are common on 1930s semis and have little usable volume until the hip is squared off. We rebuild the gable in brick or block, extend the roof structure, form the rear dormer and finish the new floor, keeping the front roof slope looking as close to the original as possible.
- Volume calculation and planning check
- Gable wall build in brick, block or render
- En-suite and fire-protected escape route
What will a hip-to-gable loft conversion cost?

| Hip-to-gable loft conversions | Guide price incl. VAT |
|---|---|

| Double hip-to-gable (detached house) | £70,000 to £95,000 |
Do you need permission for a hip-to-gable loft conversion in St Albans?
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 St Albans homeowners check first?
- Matching old clay tiles can be difficult; reclaimed tiles are often used.
- The new gable is usually rendered or built in matching brick.
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.
- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
