Waited until I had proper concrete base before erecting it. Found the corner walls difficult and I do think the design could be made more user friendly. The doors do not meet properly (too close) and there is no way to adjust them. Found it relatively easy to erect and I think the skylight is a great idea. I like the look and feel of the material for the roof and walls. Have bolted it down due to the winds we get in the Isle of Skye. Would have given it 5 stars if not for the doors.
