Had a summer house installed almost a year ago and have had nothing but issues with it since. The gaps have opened up so much between the weather board I have had to employ a joiner to come and fix it which involved taking it almost completely apart. He said the framing hadn’t been screwed together properly only nailed and this was always going to happen and would happen with every shed and summerhouse they make if this is how they construct them! it has cost me an extra 500 to fix it. Also I’ve had to have the roof refelted after only 10 months as they used silicone to seal round the roof which ate away the silicone and turned it back into soft bitumen and just fell apart. Paul seems like an old school jack the lad who is a master of nothing clearly. The floor bounced about all over the place and had very little support underneath it! certainly avoid if possible there are plenty better options out there including alot of online options
