it's possible it's not actually "glass" but a polymer or some such wonder material....  in our long winters the thing is going to be all gray reflecting the sky.  we don't need more gray - and glass is a "cold" material - angles, gray sky and glass  - makes me shiver just to think of it.  I think the design stinks as is.  maybe modify the look with something like wood to "warm" it up, and make it more inviting. incorporate lots of light giving windows.
