I bought this shed about 3 months ago to use as a mini observatory for my telescope. The lift up roof was one of the main attractions. The shed was fairly easy to build by myself. It has proved completely water proof and so far has served me well. Lifetime would have a huge market in the armature astronomer field of they were to improve the roof design. Currently I have it sorted that the roof opens east, but that completely blocks the view for the telescope in that direction. If the roof split and rolled off to the sides that would be a huge improvement..... But, so far I am happy with it for the purpose I bought it for.
