Host Joan Kohn visits with architect Keith Malcolm Brown of Period Architecture and Interiors to learn more about adding moldings, columns, medallions and other architectural features to living spaces. Brown explains that most moldings originally were functional. For example, baseboards were also called mop boards because they protected plaster walls during cleaning. Most molding was designed to disguise a wood joint, and only later evolved into a design element. Together, Kohn and Brown tour a city condominium he refurbished in stately Edwardian style, replete with the curves and columns characteristic of this Greek revival period. For example, an arch over the fireplace with beautiful molding details creates an elaborate focal point in the master suite. He suggests that different styles of molding can be carefully mixed and matched, if desired. Architectural elements for remodeling are easily found on the Internet.
