Since basements are partially or completely underground, they often have inadequate windows. Adding more or larger windows to a basement can make it feel less claustrophobic and provide a welcome source of natural light. Installing an egress window will also allow the opening to serve as an exit in the case of an emergency.
If the basement is underground, remove the soil and cut an opening in the wall to accommodate the window. To provide an attractive view and allow the window to serve as a means of escape, a retaining wall made of timbers can be laid in a stairstep design.
