49 E 21St St

A landmark pre-war condominium in Manhattan's Flatiron/Gramercy border, this 12-story boutique building was constructed in 1913 and later converted to condominiums. The property contains 21 residences, primarily two- and three-bedroom loft-style homes, many with flexible layouts that accommodate a home office or convertible third bedroom. Typical interior characteristics include very high ceilings (often 11–13 feet), oversized picture windows, exposed or beamed ceilings, wide-plank oak floors, generous closets and thoughtfully renovated kitchens and baths with premium finishes. Common elements favor pre-war proportions paired with contemporary upgrades: entrance foyers and formal dining areas in several units, double vanities in principal baths, and in-unit washers. Shared building amenities center on full-service convenience and outdoor space — a 24-hour doorman/concierge, resident manager/superintendent, a planted rooftop terrace with seating and grilling areas, and private storage lockers assigned to units. The building operates with limited density (only four units per floor), elevator service, and a pet-friendly policy that allows pied-a-terres. Located steps from Madison Square Park, Gramercy Park and Union Square, it places residents within easy reach of extensive subway lines, high-end dining, and neighborhood shopping, delivering a combination of historic character and modern urban living.
