Positioned at the intersection of Massachusetts Avenue and Sheridan Circle, 2234 Massachusetts Avenue NW offers a rare opportunity to acquire one of the most architecturally distinguished buildings on Washington, D.C.’s Embassy Row. Designed in 1908 by William Penn Cresson and commissioned by Henrietta M. Halliday, this Beaux-Arts limestone property has served as the Irish Embassy since 1949 and retains its original grandeur across five levels. The building’s Louis XVI-inspired façade and interiors blend 18th-century French and English design elements, featuring gracious millwork, expansive reception halls, and a flexible layout suited for diplomatic, academic, or cultural institutions. With dual frontage and a circular driveway for easy drop-off, the property includes elevator access to all floors, a conference center, event space, and a separate basement unit. Its location within walking distance of Dupont Metro and surrounded by dozens of embassies and boutique hotels enhances its prestige and accessibility. This offering includes the potential to combine with the adjacent 2232 Massachusetts Avenue, creating a landmark compound in the heart of Washington’s diplomatic corridor. Whether preserved as a single-tenant headquarters or adapted for institutional use, 2234 Massachusetts Avenue NW represents a once-in-a-generation investment in one of the city’s most storied neighborhoods.
