Raised panels, the most traditional wainscoting style, go back to colonial days. The decorative raise is created by beveling the edges of the panel. Common height is between 30 and 40 inches, but the design can be adapted for higher-ceilinged spaces by adding a center rail to create two rows of panels. The rails, stiles, and panels fit together the same way as in traditional flat-panel assemblies. The bottom rail can double as the baseboard, as it does here, or the baseboard can be built up from several pieces of molding.
