Hi, Will be getting a garden shed delivered and assembled within next few weeks so need to put in a base/foundation beforehand. I was initially just going to put down a few concrete blocks as a base to raise it above level of the garden. However, I will be laying a patio myself in an adjacent area of the garden and was thinking of just extending the patio area and placing the shed on top. Would there be any problems with laying a shed on a patio (i.e. cracking patio slabs, subsidence etc.) or would I be better off just using blocks for a foundation? Any advice, recommendations, experiences welcome. Thanks EDIT: by the way anyone have an idea of cost of hiring small electric cement mixer for 2-3 days?
