Any restrictions on garden sheds?

[craigiep]

Are there any legal restrictions on garden sheds / summer houses being placed up against a wall which divides 2 properties? Must they be under a certain height, width, a certain distance from the wall, or anything like that? Are there any circumstances under which planning permission is required for one?

Planning permission is required if it is in a Conservation Area.

I sell sheds and summerhouses all over the country and the only time i have heard of them needing planning permision is within a housing association or we sold one once to a person who lived in a barn conversion which caused problems??

I live in a Conservation Area and my neighbour had to get planning permission for a shed in his garden.
