The living room’s Art Deco sofa and armchairs by Carl Malmsten are upholstered in fabrics by Ralph Lauren Home, the chandeliers are by André Arbus, and the cocktail table, made by de la Torre, has a resin top on a base of vintage balcony railings designed by Gilbert Poillerat; the rug is by Patterson, Flynn & Martin, and the curtains are made of a Ralph Lauren Home fabric inset with panels of 18th-century embroidery.
