At the center of the house are three long, narrow windows that we plan to replace with one large window the width of two of the existing windows. We plan to block up the third window. There is no existing window behind the shrub at the front of the house. During out next phase of renovations, I want to install another window, just as large to the right of the existing windows. My feel both the windows at the front of the house should be the same size. My husband thinks otherwise. Are there any design rules for window placement?
