We want to bump out exterior walls that face our northwest view to create a dining nook beyond the kitchen and a home office beyond a seldom-used walk-in closet. Both additions would be 8' x 8'. To maximize the view I'd like fixed-pane maximum insulated windows about 7'h x 6'w on all three walls of both room additions. How much extra in initial cost and heating bills would this cost over 4'h x 6'w windows?
