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 Leeds?
In Leeds, a garage conversion typically costs £16,500–£28,000 for a single integral garage, including VAT at 20% (standard rate). Building costs in Yorkshire and the Humber run about 7% below the UK average, and the figures for Leeds are adjusted to reflect that. Design, structural calculations and council fees are extra.

Do you need planning permission for a garage conversion in Leeds?
Whether you need planning permission depends on your house and its location 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.
Where work involves a shared wall, building on the boundary, or digging foundations within 3 metres of a neighbour’s building and deeper than its foundations (or within 6 metres for deeper work), the Party Wall etc. Act 1996 applies and notices must be served before work starts.
We check this for your address before design work starts, so there are no surprises later.
