Commanding a premier corner at Massachusetts Avenue and Sheridan Circle, 2234 Massachusetts Avenue is one of the most architecturally significant buildings on Embassy Row. Commissioned in 1908 by Henrietta M. Halliday and designed by renowned architect William Penn Cresson, this semi-detached limestone property, a home for the Irish Embassy since 1949, is a rare surviving example of Beaux-Arts design on Massachusetts Avenue. Its exterior reflects Louis XVI influences, while interiors combine 18th century French and English styles with gracious millwork, grand reception rooms, and office accommodation over five floors. With its dual frontage, intact historical fabric, and flexible internal configuration, it offers a prestigious setting for an embassy, a university, an NGO or cultural institution, seeking a flagship Washington headquarters. This is a rare opportunity to acquire one of the remaining historic Embassy buildings on Massachusetts Avenue.
