Though its exterior nods towards local barns, the Field House in Ellington, Wisconsin, features an interior that is cutting-edge. Owner Robert Geller is a longtime collector of furniture and art, and here he sits on a Barcelona chair designed by Mies van der Rohe for Knoll. To the left is an Arco floor lamp by Achille and Pier Giacomo Castiglioni for Flos and a BeoLab 5 speaker from Bang & Olufsen.
