Garden Shed - Options?

[Kevin T]

I am currently renovating my property which is a 1 bedroom flat, We only have a small outside space that conist of a concrete area (approx 3x2.5m) and an adjacent area that has a shed on it. I have recently knocked down the shed as it was very old (made of rusty tin sheets etc), my idea was to but a wooden garden summerhouse that woudl fit perfectly on the spot where the old shed once stood. The problem being that the old shed was adjoined to a smaller shed that is owner by my neighbour, and because of the weird setup, If i purchase a summerhouse and put on on the old shed spot, the smaller building owner by neighbour would obscure the view and would restrict light coming into the new s/house. What do you think my options are in regard to asking my neighbour if he would mind me knockin down his small shed ? The neighbours shed is actually an old outside toilet and it measures only (1.5x1m) and is of stone construction. (roof&walls). He never uses it for storage and has only ever used the toilet when he was getting a new bathroom suite fitted in his house. Any ideas on how to approch him would be appreciated ?
