Abstract: A building panel, such as a door, wall panel, etc., is formed of a solid, planar body, having first and second opposed, major surfaces. A groove of a predetermined shape, such as a square or rectangle, is formed in at least one of the first and second major surfaces of the body. The groove has an open end and extends partially into the body. A decorative molding having a base portion complementary to the shape of the groove is fixedly mounted in the groove. In one embodiment, the molding includes opposed, outwardly extending flanges which are located to overlay the edges of the major surfaces of the body when the molding is mounted in the groove on the body. The groove and the molding may be mounted on both of the major surfaces of the body and in multiple numbers or patterns on one or both of the major surfaces of the body.
