Covering Leamington Spa

Leamington Spa is about 17 miles south of Nuneaton. We also cover Warwick (3 miles to the west), Kenilworth and Coventry.

Homes in the West Midlands

The West Midlands has a large stock of 1930s semis and Victorian terraces in red brick, so matching brick and roof tiles is often the key to an extension that looks original.

What is a mansard loft conversion?

A mansard loft conversion replaces one or both slopes of a roof with a near-vertical wall, typically at 70 degrees, with small dormer windows set into it. It creates almost a full extra storey and is common on terraced houses in towns and cities, particularly in London.

What approvals does a mansard loft conversion need in England?

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.

Mansard conversions change the shape of the roof significantly, so they usually need planning permission in England.

What should Leamington Spa homeowners check first?

  • The roof is open for longer than with a dormer, so weather protection matters.
  • Council design guides often require natural slate and lead.

From first call to completion

  1. Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
  2. Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
  3. Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
