Designer Joe Lucas gave the rear loggia of this Agoura Hills home multiple entertaining areas, punctuating them with a vintage French table from his shop, Harbinger. On one side are chairs Celerie Kemble chairs— in Chris Barrett fabric—for Lane Venture and a Century Furniture coffee table. One the other, Lane Venture sofas upholstered in Rose Tarlow Melrose House fabric for Perennials are from David Sutherland. The vintage cocktail table is from Hollywood at Home and the lanterns are Ann-Morris. Surveying the landscape is the family’s late dog, Mr. B.
