Western red cedar is one of the most enduring siding materials, says Mankins, who used it on this home. He chooses it for its "durability, weather resistance, and renewable nature," he notes. Easy to cut and finish, it weathers beautifully and contains natural oils that resist moisture. Western Red Cedar Lumber Association, 866.778.9096; www.wrcla.orgweaetxdyvaydzcwq.
