We visited this diminutive 1200 square foot Usonian today. The most striking thing to me about the house is its 6’8″ ceilings and pullman corridor width halls. This manipulation of space made the 11-1/2 foot ceiling-ed living room seem enormous.

There’s a lot of Usonian and Wright influence in a house in Rockville, which I’m still trying to find out more about.
