Hi Marc ...
It's 16' x 25' (approx). I plan on using used patio door tempered glass for most of the glazing. It is substantial (tempered) glass and inexpensive to buy. I will take a picture of it when I am building it. MoI was great for working out the details. All the parts can be cut from these drawings ... though I will have to create a set of dimension drawings, as well.
cheers,
eric
