"Unlike other reviewers I found the instruction booklet to be quite good, clear illustrations and written explanations in an easy to follow step by step format. However assembly is not easy and I would say nigh on impossible for one person. It is fiddly and frustrating, once the front and back are assembled (best to do this on level ground using a tarpaulin or similar to work on) the assembled sections must be joined by the roof ridges, here you will need two people, three would be better, to hold up the sections whilst the ridges are attached. It cannot be overstated just how important it is to have a COMPLETELY LEVEL AND SQUARE BASE! There are absolutely no tolerances built into the structure, it fits together exactly with no give in any direction, therefore if your base is not 100% spot on then panels will not fit and the door will not operate correctly. The provided base is satisfactory but the structure sits on it EXACTLY with no room for error in any direction. Mine is up and all fitted together ok, it is sufficient for my needs but I wouldn't buy this product again."
