Box-style bay windows are popular among homeowners who want to install a bay window but don’t want to mess about with the positioning of the walls.
Box bay windows have a boxy shape: they look like three windowpanes with a small roof overhang. You’ll often see these windows in front of a sink, to let in some natural light while you’re cooking up a country-fried steak. When seen from the home exterior, box bay windows are flat. The effect is as if the home siding
were bumped out to accommodate the bay window.
However, these are flexible types of bay windows that can go just about anywhere in your home. Since you won’t need to move the walls, box bay windows are less expensive to install than larger bay windows.
