When one thinks of the most common architectural styles of residential buildings around DC, modern would be very low on the list. Washington has a strong preservationist tendency, so it is not a city where modern architecture flourishes. There is a small pocket in Northwest, however, that is establishing itself as the city's outpost of modern architecture. Just a couple blocks northeast of the U Street Metro station, on 10th and 11th Streets between V Street and Florida Avenue, there is a concentration of recently built homes that give the neighborhood a very un-DC, modernist feel. Photos of the best specimens after the jump.
