Im getting a 22ft by 10ft cabin, going to split it off and one side for water etc and other side for paper work, comp etc
Be sure to apply for planning permission first - I didn't and the council gave me the option of pulling it down or lowering the roof by a foot.
That was fun
Supported the roof on split uprights held together with G cramps, cut a foot wide section out of the wall all the way round (20 foot x 8 foot) and then lowered the roof down to meet the wall, fixed it back together with battens screwed to both ends of the cut wall frames.
Was alright till the wind picked up while the roof was balancing on the temporary uprights - Lise was hanging onto to it while I frantically rushed round lowering each support in turn till it was down far enough
THERE ARE STRICT CONTROLS ON WHAT YOU CAN BUILD AND WHERE - FIND OUT BEFORE YOU START. AND YES.........THAT DOES INCLUDE GARDEN SHEDS
