Hoffmann Architects + Engineers receives Lucy G. Moses Preservation Award from New York Landmarks Conservancy

An Icon of Beaux-Arts Military Architecture

The 69th Regiment Armory, at 68 Lexington Avenue in Manhattan’s Flatiron district, was completed in 1906. The building is one of the first armories from the period to jettison the prevailing medieval-inspired castellated style in favor of Beaux-Arts architecture.

Home of the “Fighting 69th,” a fabled unit of the New York National Guard whose members served with distinction in the Civil War and World Wars I and II, the armory remains an active military complex for the Army National Guard. In addition, the barrel-vaulted drill hall is used as an exhibition space, serving as the site of the first major exhibit of modern art in America in 1913.

Showing Its Age

Integral to the armory’s character are its classically configured wood-frame windows. Tall and narrow at the ground floor, branching into tripartite groups in stone-trimmed oriels at the main level, then piercing the Mansard slate and copper roof at upper stories, the symmetrical windows define and ornament the masonry facades.

Concerned about deterioration and inoperability of the existing windows, the New York State Office of General Services retained Hoffmann Architects + Engineers to conduct an investigation and provide recommendations for rehabilitation. After a meticulous window-by-window study, Hoffmann’s team concluded that, due to the advanced degree of deterioration, one-for-one replacement of all existing windows and frames would be the best approach.

Ready for Active Duty

While the 69th Regiment Armory is a stunning example of turn-of-the-century Beaux-Arts design, it is also an active military facility. In addition to faithfully adhering to standards for the treatment of historic properties, the design team at Hoffmann also had to consider the very modern demands of a secure Army property. The window design, therefore, met the safety and security standards established by the New York State Division of Military and Naval Affairs, as well as the latest energy codes.

Integrating insulating glazing units that met Department of Defense anti-terrorism performance standards for blast resistance was a challenge when maintaining the original window profiles. Add to this the compound difficulty of incorporating specialized coatings and air cavities within windows to achieve Energy Conservation Code requirements, as well as securing the heavier multi-pane units in the wall openings, and getting the designs just right was a massive undertaking.

The result was the stunning transformation now recognized by the New York Landmarks Conservancy for preservation excellence. The restoration succeeds in returning the building to its Belle Époque aesthetic, with vastly improved safety, security, and performance.
