Frequently Asked Questions on

Garage Conversions

  • Do I need planning permission for a garage conversion?
  • Most people do not need planning permission for their garage conversion, provided the work being done is internal and you’re not enlarging the building. However, some properties may require planning permission, especially listed buildings and those in conservation areas.
    Allerton Windows conducts a full technical survey of your home to determine if you need planning permission. If you do, we’ll help you fill in any relevant forms.

  • What's the typical cost of a garage conversion?
  • The costs associated with garage conversions depend on the size, condition, and plans for the space. Single garages usually cost between £5000 - £15,000, and double garages cost between £12,000 - £30,000.

  • How long will it take to turn my garage into a living space?
  • Most conversions are finished within four weeks. Double garages can take up to six weeks, and more complex projects and buildings in disrepair will need extra time and care.

  • Are garage conversions a good investment?
  • Yes, a garage conversion can add 10 - 20% more value to your home. It also transforms a disused part of your property into a living space that you can enjoy.
