I don't believe planning permission is required for a garden
shed or a summer house. It is surprising the uses there are
for a good summer house.
Unless you live in a conservation area planning permission is not necessary
for "utility" buildings which are not habitable. They must be separate from
the house, built entirely within your own ground and meet maximum height
limits. (Hence the recent fury over a man who built a games room and
gymnasium that was larger than his house. Planning officials could do
nothing.)
