Adding a garden room is on the wish list of many homeowners. And if you've got one, you might be making the most of it, but could it actually be breaking the law?

At the start of the process, it's all too easy to get caught up in looking for garden room ideas that will give you your ideal space. Then you might be focused on garden room costs, choosing the right supplier or swatting up on how to build the structure yourself. You might also be factoring in how to add electricity to the new room and scoping out the best spot for it to be located.
