When I received this I was dubious as it looked very flimsy. It is not a hard plastic more like a double layer of cordek which we use at work to lay on floors but once it is assembled your opinion changes, it is solid after you add roof supports and framework and is very attractive once completed. The floor is not that strong but if sitting on decking is absolutely fine. All in all I am very happy after building it. Let’s hope it lasts well and hold up against the Scottish weather
