This family had a lovely view from their three season room but couldn’t enjoy it because they had seal failures in all of their windows.  The old windows consisted of all picture windows of the same size.  We removed these and went with a new layout.  To optimize the view we changed the layout to having one large picture window in the center and a smaller sliding end on each side.  This layout created the least amount of obstructions and still allowed for air flow in the room when they were open.
