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 Chadderton?
In Chadderton, a barn conversion typically costs £1,700–£2,800 per m² of floor area, including VAT at usually 5% (reduced rate for creating a new dwelling).

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.
