Well, it finally looks like and Observatory. The Roof is now up and rolling and the Obs is almost complete.

Well not quite, there is still a lot of small things to still do but if you look back of how much has been done, I can confidently say we are almost there.
One of the main problems we faced was making sure that Observatory will be properly waterproofed. So we designed the roof to fit under the stationary roof when it's closed. We used form plywood for the roof which will later be covered will some sort of roof material.
The wall cladding will hopefully be put up this weekend but it's awesome that most of difficult jobs have been completed, so it is just the little things left to do.
Here are some pictures of the roof.
