Description
Residence 10C at 49 East 21st Street is a stunning, sun-drenched 1,461-square-foot pre-war loft showcasing two bedrooms, two bathrooms, a flexible layout with a potential third bedroom, and iconic landmark views of the Flatiron Building. Rarely available, C-line residences on the higher floors enjoy a coveted western exposure framed by four dramatic picture windows that fill the home with natural light. Elegant 11-foot beamed ceilings, 10 oversized windows, and a gracious open floor plan create an effortless flow between living and private spaces. The expansive 40-foot great room is ideal for entertaining, with light streaming in from multiple exposures and plenty of room for both living and dining areas. The chef’s kitchen is beautifully appointed with a large central island, bar seating, a built-in wine fridge, and generous custom cabinetry—perfect for hosting gatherings or quiet evenings at home. The flexible layout allows for a seamless conversion to a third bedroom or the continued use of this space as a formal dining room, playroom, or den, accented by custom millwork and floor-to-ceiling built-ins. The primary suite comfortably accommodates a king-size bed and features a walk-in closet leading to a spa-inspired en suite bath with double vanity and oversized stall shower. The second bedroom is equally spacious, offering custom closets and elegant built-ins for additional storage. A private storage locker, in-unit washer/dryer, and abundant closet space complete this beautifully curated home. 49 East 21st Street is a boutique pre-war condominium offering a full-time doorman, resident manager, and landscaped rooftop terrace. Recent building enhancements include newly designed hallways, upgraded roof deck furnishings, and a new barbecue grill. Perfectly positioned near Madison Square Park and surrounded by some of Manhattan’s most celebrated dining destinations—Eleven Madison Park, Gramercy Tavern, and Union Square Café—this home captures the essence of Flatiron luxury living, with every major subway and convenience right at your doorstep.
