I’m currently on building a lean to roof at the rear of my property, bordering a neighbours fence. The lean to is 2.9m from ground level and extends approx 2.7m out from the house and 3.6m long, however our neighbours garden is approx 2 foot higher than ours so the lean to is roughly 2.4 on their side. I’ve attached a photo below for information (excuse the feet). Can anyone possibly advise as to whether this would require any type of planning permission. Many thanks in advance
