Hi, I am new to this forum, I am about to start work on a 9m x 3.5m flat roof orangery on my home. Its so exciting . I will do most of the work myself which will be a challenge as I am not in the trade and a bit crazy . I have watched this forum for some time and used it again today to answer a small problem I had, so I hope that I can get help and that I can help other members. Thanks. BC
