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 Shrewsbury?
In Shrewsbury, a garage conversion typically costs £17,500–£29,000 for a single integral garage, including VAT at 20% (standard rate). Prices in the West Midlands sit near the national average for this kind of work, and the range for Shrewsbury reflects that. Design, structural calculations and council fees are extra.

Your quote will depend mainly on:

- Integral, attached or detached
- Heating and flooring
- Foundations under the old door opening
A guide range is only a starting point: the guide price tool gives an instant figure for your size, and a free survey turns it into a fixed quote.
Do you need planning permission for a garage conversion in Shrewsbury?
Before anything is built in Shrewsbury, 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.
