155 E 73Rd St

A pre-war cooperative erected in 1923, this nine-story, small-footprint building contains primarily one-bedroom apartments arranged at about four units per floor. The exterior presents a restrained, early 20th-century townhouse scale that fits a landmarked carriage-house block on the Upper East Side. Interiors typically retain classic period details — hardwood floors, high ceilings, decorative fireplaces, crown moldings and original moldings — alongside modernized kitchens and bathrooms in many units. Apartment layouts favor an entry foyer that separates living and sleeping spaces, with some units offering windowed kitchens, formal dining areas, dens, and built-in bookcases. Common areas are modest and well-kept: a colonial-style lobby, wood-paneled elevator, part-time doorman, live-in superintendent, basement laundry, and bicycle storage. The building is pet friendly, allows pied-à-terres and limited financing (typically up to 75%), and has small ongoing assessments at times. Street-level access opens onto a quiet, tree-lined carriage-house block three blocks from Central Park with close proximity to Lexington/Third Avenue retail, restaurants and multiple subway lines, delivering a conventional Upper East Side lifestyle blending historic character and practical conveniences.
