Well I guess the first thing is, GLAD that your builder was nice about it all!
I don't know. For me it would depend on what it looks like INSIDE. As I said originally, plant a conifer in front to one side of the window and you'll never know. But if it looks crap inside, well that is another matter. I guess it also depends on how important those 4 weeks are to you?
All I know is, I'd be looking closely at everything else now.....
