What can you build in your garden without planning permission?
If you do not want the hassle of applying for planning permission, your garden room must meet specific requirements. As well as the maximum size, you can only build a garden room that is up to 50% of your garden’s total area, which includes your front garden. It must also not be used as a permanent bedroom. There are also some specific requirements for listed properties and those in Areas of Outstanding Natural Beauty. Please ask if you would like further information.
