It is NOT the best place for double hung windows. Each window glass would be over 3 feet wide. That is pushing it. why not consider my reccomendation to put a 3ft (+/-) high picture window full width with awning windows either above or below, 3 foot wide awnings are do-able, and the center post between the 2 will not cost a lot of glass space. Or you could put in a 3 section top or bottom with 2 awnings and a fixed pane. It will look good. It will work well. It won't break the bank, and it will continue to work for a LONG time. On THAT house, I'd put the awnings on the bottom for best visual effect. Any other current or former Window Pros on the list???? You are getting my experience for free. I used to get paid for it.
