Covering Penarth
We work in Penarth (CF64) and the places around it, including Cardiff, Whitchurch and Barry.
Homes in South 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 hip-to-gable loft conversion?
A hip-to-gable loft conversion rebuilds the sloping side (the hip) of a semi-detached or detached house roof as a vertical gable wall, extending the ridge and creating enough space for a staircase and rooms. It is usually combined with a rear dormer.
- Planning and building regulations checks under Welsh rules
- Gable wall build in brick, block or render
- Extended ridge and roof structure

Planning and building rules in Penarth
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. 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 change the price or programme?
- The new gable is usually rendered or built in matching brick.
- Scaffolding goes up on the side of the house, which may need a neighbour’s agreement.
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.
- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
- 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.
Hip-to-gable loft conversions: common questions
How long does it take?
About 9 to 13 weeks on site.
Will the roof tiles match?
We match the tiles as closely as possible, using reclaimed tiles where the originals are no longer made.
Can you visit a house in Penarth 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.
