It's the question we get asked more than any other. Do you need planning permission for a garden room?
Most of the time the answer is no, because most garden rooms fall under permitted development. That changes if it's within two metres of a boundary and over 2.5 metres tall, if it sits in front of the house, or if you want to sleep in it or rent it out. Listed buildings are different again, and inside the Lake District National Park the rules are tighter.
That's why we check every site properly before any design work starts, so there are no surprises later.
