Hi Everyone

I have just removed my old garden shed which sat on concrete foundation. The thickness overall of the base is 7inches i think, and the size is 18ft width x 6ft length, the concrete is about 3 1/2 thick. I have a 18x12 ft logg cabin to be placed there . I have cut out the extra footings so the whole cabin can fit plus a bit extra. I wanted to know 2 things, which is the best solution. Can i just concrete and butt it up to the existing concrete. The next question on the old existing base would it with stand the weight for my new cabin. It looks solid enough and it has a hair line crack in the middle from end to end on the 6ft length ways. Please could you advise me the best way and to save me cost and time and i could do it myself.. here is the link to the cabin. its a dalton cabin and it the first one...

many thanks
