The deep window sills are one of the attractive features of straw bale building. The walls are as thick as the straw bales, and the window is mounted flush with the outside of the wall to prevent rain or snow from damaging the plaster below the window. Crafting a beautiful deep window sill from either wood, tile, or plaster creates a space for sitting, leaning out to admire the view, or decorating with photos or plants.
