Built on 46 acres next to the Tanglewood property in the early 1940s, this Bauhaus-influenced house was the home of abstract artists Suzy Frelinghuysen and George L. K. Morris. Their chosen style was Cubism, which they pursued long after it had been abandoned by better-known practitioners. Works by some of those artists -- Braque, Léger, Gris, and Picasso -- can be viewed alongside the canvases of the owners. Visits are by tour only.
