Hi all .Iam having a similar problem .My neighbour is in the middle of erecting a summer house , It is 2.8m high and about 2ft away from the boundry which is a 6ft fence It has been built on a raised patio .It is imposing and is going to be even higher when he adds tiles to the apex roof , Does anyone know if he is breaking the rules He says he does not need planning permision !
