I am roughing in the framing on a project that will have many windows (all open). On the front side you have a door and windows that are 61 1/2" high for the rough in. On both sides and the back all the windows are 60 1/4" high. One will be able to see two sides of the building and since it's mostly windows possibly the height difference. The question concerns if one should align the bottom edges to the same height, the top edges to the same height, or split the difference. Any opinions?
