A Frank Lloyd Wright home in St. Louis is a rare sighting, in fact there are only 2, this is one, Pappas House, on sale from the original owners. The architect only built two in the Gateway City and one of them is currently for sale. Designed in 1955, the Usonian-style home is formed from tinted concrete blocks and situated on over three acres. The 2,310-square-foot interior features matching stained concrete floors, high ceilings, and exposed block walls. More than 500 glass inserts and clerestory windows funnel in natural light while glazed doors open to outdoor terraces. Philippine mahogany panels, cabinets, and Wright-designed furniture accent the rooms and are included in the sale. Listed on the National Register of Historic Places, this home is a unique opportunity to own a historic property.
