We want to get ds This for his 4th birthday but after reading this and going on to speak to the council it looks like we need planning permission. Is it just me or is that just ridiculous?? We could buy a climbing frame as long as it didn't go higher than 6 feet but it becomes an issue when it is raised off the ground more than 30cm. In that case do trampolines need planning permission as the big ones are usually more than 30cm from the ground with a ladder and are definitely higher than 6 feet with the safety net
