Beekman Mansion is a 10-story, 36-unit cooperative completed in 1925 and set on a quiet, tree-lined cul-de-sac along Beekman Place in Midtown East. The building’s prewar masonry façade and modest scale read as a traditional Manhattan residential block; interiors emphasize period details typical of the era. Units are primarily three-bedroom layouts and maisonettes that blend townhouse-like circulation with co-op services. Common interior features found across residences include high ceilings, crown moldings, recessed lighting, herringbone and wide-plank floors, formal dining rooms, entrance foyers, built-in cabinetry, wood-burning fireplaces, and windowed kitchens often with pantry or eat-in space. Several homes have been reconfigured historically (guest or maid rooms, libraries, and home offices are common), and many units offer river or tree-lined street views. Building amenities and services are full-service: 24-hour doorman, live-in superintendent, hand-delivered mail, laundry and storage in the basement, fitness room, and on-site sidewalk landscaping. The coop permits pets and pied-à-terres with board approval and allows moderate financing per house rules. There is no on-site garage; street and neighborhood parking options are typical for the area. Located adjacent to Peter Detmold Park and a short walk to the East River esplanade, the property sits within a secluded residential enclave while remaining close to restaurants, transit (Lexington Avenue subway and multiple bus lines), and Midtown conveniences.
