Built in 1918, this nine-story prewar cooperative is a boutique residential building on Manhattan’s Upper East Side with 22 apartments and primarily two residences per floor. The exterior presents a traditional brick-and-stone façade with a canopied doorman entrance leading to an attractive lobby and an elevator serving semi-private landings. Units are large, classic multi-room apartments—many configured historically as eight-room or seven-room homes—featuring high beamed ceilings, wood-burning fireplaces, herringbone hardwood floors with border inlay, crown moldings, built-in bookshelves and oversized picture-style windows that admit abundant southern light. Typical interiors include formal entry foyers, separate formal dining rooms, windowed eat-in kitchens with butler’s pantries, staff/maid rooms (often repurposed as offices), dens and generous closets; several listings note modernized kitchens and baths with high-end appliances and in-unit washers. Building services include a live-in superintendent and a doorman on extended daily hours, communal laundry, bike storage, basement storage and on-site staff. Pets and pieds-a-terre are permitted and the co-op allows up to 50% financing; pied-a-terres may be reviewed case-by-case. The location places residents equidistant from Central Park and the East River promenade and within easy walking reach of Lexington and Third Avenue shops, restaurants and subway access, offering a quintessential Upper East Side lifestyle that blends prewar scale with modern conveniences.
