A Distinguished Gilded Age Landmark in Dupont Circle Prominently positioned at the intersection of 20th Street and Hillyer Place, overlooking Connecticut Avenue just north of Dupont Circle, 1614 20th Street NW is a distinguished historic residence representing the architectural grandeur of Washington's Gilded Age. Originally constructed circa 1893–1894 for prominent businessman Alfred S. Gillett, the property was designed by celebrated Washington architect Thomas Franklin Schneider, whose contributions to the city's architectural landscape include some of its most recognizable late nineteenth-century buildings. Known historically as the Alfred S. Gillett House, the property is distinguished by its commanding corner presence, richly articulated brick and stone exterior, and striking turret, reflecting the elaborate architectural sensibilities of the period. Conceived as an imposing private residence, the building embodies the elegance and craftsmanship that defined Dupont Circle's emergence as one of Washington's most prestigious residential enclaves. In 1951, the property entered a new chapter when it was acquired by the National Fisheries Institute and adapted for professional office use. Subsequent ownership by a prominent Washington attorney further established its institutional and commercial character. More recently, the building became the headquarters of the Association of American Law Schools, continuing its longstanding role as a distinguished address for professional organizations. Encompassing approximately 9,145 square feet across four principal stories, the building retains many of the architectural characteristics of its residential origins, including historic wood paneling, decorative millwork, generous ceiling heights, and fireplaces. Complementing its historic character are practical amenities suited to contemporary office use, including elevator access, a roof terrace, and off-street parking. Situated within the Dupont Circle Historic District, just moments from the neighborhood's celebrated restaurants, galleries, embassies, and cultural institutions, and approximately one block from the Dupont Circle Metro station, the property occupies an exceptionally convenient and prominent location. 1614 20th Street NW represents a rare convergence of architectural significance, distinguished provenance, and contemporary professional utility, an enduring Washington landmark with a remarkable history and a compelling presence in the heart of Dupont Circle.
