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 Deal?
In Deal, a garage conversion typically costs £20,000–£33,500 for a single integral garage, including VAT at 20% (standard rate). Building costs in the South East run about 12% above the UK average, and the figures for Deal are adjusted to reflect that. Design, structural calculations and council fees are extra.

Do you need planning permission for a garage conversion in Deal?
Before anything is built in Deal, we confirm which approvals apply 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.
We check this for your address before design work starts, so there are no surprises later.
