Do you need planning permission for a garden room? 🤔

It’s one of the questions we get asked all the time — and in many cases, the answer is no.

Most garden rooms can be built under permitted development, provided they meet certain requirements. Of course, every property and project is different, so it’s always important to check what applies to your plans.

In this reel, Ralph explains the basics and what you need to know before getting started.
