Hi there, sorry for the delay in responding. Yes, we specify window systems to achieve the unobstructed corner view quite often. This system was manufactured by Blomberg Windows, however, they are no longer in business. We have also used Fleetwood Windows, and for the Seattle area, I would definitely look into them. The main issue with corner glass window conditions is that the two pieces of single pane glass are butted together with a caulk joint, so even in a best case installation, you are relying on a caulk joint as your primary source of weatherproofing. Fleetwood makes a double pane version that might be bettter suited to your environment, though you will see a seam at the corner where the glazing panels meet.

Blomberg is back in business under new ownership. http://blombergwindowsystems.com/

Thanks for the heads up!
