Humble materials can pull off a high-end look. This backyard transformation began by installing a 10-foot-wide by 30-foot-long iron pergola. Then, wisteria was planted, which in time turned into a leafy canopy overhead. To anchor the space, an outdoor fireplace was constructed from cinder blocks lined with fireproof brick and covered in stucco. And all the furniture and accessories that decorate the space were chosen to withstand the elements but age gracefully, resulting in an inviting spot for alfresco entertaining.
