Leamington Spa garage conversions: your questions
Questions about your own house? Send them with your enquiry and we will answer them in person.
Ask us a questionDo I need planning permission to convert my garage in Leamington Spa?
Usually not. Turning the garage into a room from the inside is permitted for most Leamington homes. Get advice first if the house is in a conservation area or you are extending as well. The same goes for estates that lost their conversion rights when built. Warwick District Council.
Will losing the garage cause a parking problem in Leamington?
Rarely. Time after time, Warwick District planning officers have written that losing a garage leaves enough parking. Across the district, parking caused only one refusal in our records, in Warwick in 2018.
Does the Leamington neighbourhood plan affect a garage conversion?
Only if you change how the front looks. One local refusal cited the Royal Leamington Spa Neighbourhood Plan, because a front extension added to the conversion was out of character. A new window and brickwork in keeping with the house avoid that.
Can I turn my garage into a home office in Leamington?

Can I keep half the garage for storage?
You can. We build a wall across the middle that is insulated and fire-resisting. The new room sits behind it, and the garage door still opens onto your storage. Expect it to start from around £9,000.
How long will the work take?
For a single garage, the building work is usually done in two to four weeks. Plumbing a shower room or opening into the house stretches that. Ask about the timing for your garage at the visit.
