What is a barn conversion?
A barn conversion turns an agricultural or rural building into a home while keeping its character: the brick or stone walls, roof timbers and large openings. It involves structural repair, insulation, new services and often a new floor slab.
How much does a barn conversion cost in Kenilworth?
In Kenilworth, a barn conversion typically costs £1,750–£2,900 per m² of floor area, including VAT at usually 5% (reduced rate for creating a new dwelling). For a typical 150 m² project that is roughly £262,500–£435,000. Prices in the West Midlands sit near the national average for this kind of work, and the range for Kenilworth reflects that. Design, structural calculations and council fees are extra.

Do you need planning permission for a barn conversion in Kenilworth?
Before anything is built in Kenilworth, we confirm which approvals apply in England. In England converting an agricultural building into a home needs either full planning permission or prior approval under Class Q of the permitted development rules, which limits floor space and the number of homes. Listed barns also need listed building consent.
Building regulations approval comes from the council’s building control service or a registered building control approver. The work is inspected at key stages, such as foundations, drainage and insulation, and a completion certificate is issued at the end.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
