I've just bought a 5 x 5 metre summerhouse. I've dug an areas out of mud to create a flat surface and have bought this on eBay http://www.ebay.co.uk/itm/171815217910. I've also had 2.5 tonne of gravel to fill inside the base. The sumnerhiuse come with timber floor joists. My plan is to fit a damp proof layer on top of the gravel/ecobase and then the floor joists and then the summerhouse. It's a little late to ask now sauce bought all the bits be peices. Just wanted to check if there's any glaringly bad problems with the way I'm going about this?
Thanks in advance.
