Not sure, but I'm getting a shed in the next two weeks (found Kelly's barna sheds and Ballyfree to be the best quotes for a wooden shed - 6x8 ft around €365, 6x10ft €490).
What I'm planning on doing this weekend is get some concrete blocks, measure out the plot and lay them down on it. I'll then get a plank of wood and a spirit level and check to see if the blocks are level, and dig them down a bit where necessary to get it all level on well compacted soil.
Was thinking of laying 1000gauge polythene underneath it all to stop weeds growing - anyone know if this is a good idea?
