The answer to this is really form follows function, but ... I still must put it out there for conversation.
My loft window. The lovely little window that will be a custom stained glass work of art just inches from my pillow. Will it have the "eyebrow" arch design? Or will it open?
The arch isn't hugely pronounced, but --
I really can't imagine not being able to open that window... even if my skylights do open...
There's a matching one on the opposite end - it may end up disguising my air conditioner though...
(Sorry, neither of those angles are great...)
So, the window shape is probably going to have to change to a rectangle from the arched. Will that be so terrible? It just hadn't occurred to me that that shape would prohibit it from opening. Ahh the learning curve.
