Been helping a mate put up a shed.
There are two ways to get a shed put up here.
a) contact Skinners, given them money, they come round and put up the shed and it last for ever
b) go on the interweb buy one cheaper and self assemble and absolutely nothing fits as cheap companies don't use CAD/CAM. There was a 70mm gap between the two doors and nothing else lined up and they'd sent the wrong base
