What is a garage conversion?
A garage conversion turns an integral or attached garage into habitable space, such as a study, playroom, bedroom or utility. The garage door is replaced with a wall and window, the floor is raised and insulated, and the walls and roof are brought up to building regulations.
How much does a garage conversion cost in Cumbria?
In Cumbria, a garage conversion typically costs £17,000–£28,000 for a single integral garage, including VAT at 20% (standard rate). Building costs in the North West run about 6% below the UK average, and the figures for Cumbria are adjusted to reflect that. Design, structural calculations and council fees are extra.

Do you need planning permission for a garage conversion in Cumbria?
Here is how the rules work for a garage conversion in England. In England converting an integral or attached garage usually does not need planning permission, unless a condition on the house removed permitted development rights (common on estates built in recent decades) or the house is listed. Building regulations approval is always needed.
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.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.
