42 E 20Th St

A landmark late-19th-century Beaux-Arts condominium, the building rises nine stories and contains a small collection of spacious loft-style two- and three-bedroom residences. Converted to condos in the early 2000s, the property preserves prewar character—high ceilings, oversized Pella windows, original cast-iron columns and generous room proportions—while integrating contemporary finishes and systems. Interiors commonly include formal entry foyers, den spaces, pantry or laundry rooms, walk-in closets, double-vanity baths and details such as maple or wide-plank hardwood floors, solid-core doors and modern kitchens with upscale cabinetry and appliances. The building is served by a keyed elevator, video intercom and an on-site superintendent/porter who staffs the building seven days a week. A planted common roof deck with seating, grill and children's area provides private outdoor space; pets are permitted. Located midblock in a prime Flatiron/Gramercy corridor close to Madison Square Park, Union Square and multiple subway lines, the building combines historic architecture with large, light-filled loft residences and convenient neighborhood services and dining.
