Covering Horley
We work in Horley (RH6) and the places around it, including Crawley, Redhill and Reigate.
Homes in the South East
Many South East homes are inter-war or post-war semis and detached houses with room for rear and side extensions, while historic town centres and villages bring conservation area and listed building controls.
What is a mansard loft conversion?
Mansards are a bigger structural job than other conversions because the roof is largely rebuilt. They normally need planning permission, and many councils have design guides setting the angle, materials and window style. We prepare the design to those guides and build in slate, lead and timber or approved alternatives.
- Structural design and party wall process
- Roof removal and new mansard frame
- En-suite, electrics and fire safety

Planning and building rules in Horley
In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.
Mansard conversions change the shape of the roof significantly, so they usually need planning permission in England.
What should Horley homeowners check first?
- Council design guides often require natural slate and lead.
- Scaffolding and a temporary roof are usually needed.
How does the project run?
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- 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.
Mansard loft conversions: common questions
How long does a mansard take?
Around 10 to 14 weeks on site after planning approval.
Why choose a mansard over a dormer?
A mansard gives more usable space and often fits a street better where neighbours already have one.
