An unexpected downside of landmarking an interior is that movable components are not part of the deal. This is sadly true of the elegantly modernist furniture, place settings, and graphic design—even the logo—integral to the identity of the ultra-luxe Four Seasons Restaurant designed by Philip Johnson in the Seagram Building at 52nd and Park Avenue in New York. Yes, the landmark protection for the 29,500-square-foot space for the Grill Room, Pool Room, and lobby includes the swank bronze-railed stairways, walnut-paneled walls, sleek aluminum ceilings, and the ebonized oak or travertine floors. It also applies to the swagged anodized-aluminum beaded curtains and to the gold-dipped brass-rod sculptures by Richard Lippold suspended over the bar and mezzanine of the Grill Room. But the rest of this gesamtkunstwerk will be auctioned off on July 26, 10 days after the fabled 57-year-old culinary and architectural institution closes.
