A bow window is a type of architectural feature that protrudes from the exterior of a building, creating a curved shape. It typically consists of multiple window panes arranged in a gentle arc, allowing for a wider view of the outside. Bow windows are often found in residential homes and can enhance both the aesthetic appeal and natural light in a room. These windows are similar to bay windows, but while bay windows have a more angular design, bow windows offer a softer, rounded appearance. They can be used in various styles of architecture, from traditional to modern, and are popular for creating cozy reading nooks or expanding living spaces.
