Bow window

A bow window or compass window^[1] is a curved bay window.^[2] Like bay windows, bow windows add space to a room by projecting beyond the exterior wall of a building and provide a wider view of the garden or street outside than flush windows, but combine four or more facets, differentiating them from the more common three-sided bay window.^[3] Casement windows are often used for ventilation.
