In classic architecture, stone on the walls was an often-seen design element. Due to its natural beauty and durability, stone is an obvious choice in these applications. In the photograph seen here, each of the natural stone materials on display is shown as a detailed base trim piece, cut into 1-inch squares, slab form, a rounded trim piece, cut into pencil widths and a cap trim piece. And these forms are just a small part of what is available. Most stones are either available in, or can be custom cut to, almost any size and shape you might want. The stone itself has such wonderful, natural texture, and combining these different profile pieces in a space creates another texture and dimension. Like many other stones, the veining in a white Carrera or Calacatta marble are at their most beautiful when seen in slab form. And often, the simplicity of running the same material across the floor and up the walls can add an incomparable elegance to a space. Aside from the more common use of stone materials on the wall in a bathroom, it can be a beautiful treatment in an entry area or a kitchen or mudroom. And the rich tones of some of the darker stone materials can add an earthy warmth to an office or study. When budget allows, consider borrowing from the Old World, and using stone on your walls.
