This massive “fire screen” was made for a family in Aspen, Colo., by Ron Arad. (The fire it screens is a video.) And it may be available, say the designers who commissioned it, Tony Ingrao and Randy Kemper. On either side, paintings by Ross Bleckner. The designers poured a lifetime’s worth of collecting into this sitting room. At right, an ancient bronze leg, and a Giacometti lamp.
