About This Home

Welcome to 4 West 21st, a modern luxury residence in the heart of the Flatiron District. With 1620 square feet of luxurious interior space and 270 square feet of private outdoor space, apartment 2D is a perfect combination of beautifully upgraded interiors, practical configuration, and a welcoming private terrace. This light-filled and spacious two-bedroom plus home office was thoughtfully designed with high ceilings and excellent attention to detail. The updated kitchen features SubZero, Bosch, and Miele appliances, a wine refrigerator, and excellent storage space. The open living area boasts floor-to-ceiling windows allowing for abundant sunlight along with wide plank oak flooring, as well as distinctive soffeted and recessed lighting, custom millwork, and electronic shades. It is a perfect space for relaxing or entertaining guests. Beyond the living area there is a beautifully outfitted and private home office featuring custom sliding doors, recessed lighting and ceiling fan. This could also be used as an interior third bedroom. The primary bedroom features floor-to-ceiling windows, an enormous walk-in closet, primary five-fixture bath with dual vanities, heated floors, and large soaking tub. The ultimate luxury is the adjacent 270 square foot terrace directly off the bedroom. The secondary bedroom is also en-suite and faces south, allowing for generous sunlight throughout the day. Designed in 2006 by renowned architect Hugh Hardy, 4 West 21st Street residents appreciate the expanse and character of a prewar loft coupled with the luxurious amenities and finishes of new construction. Amenities include a 24-hour doorman, state-of-the-art fitness center, parking garage, 2,500 square foot landscaped courtyard with children's play area, and live-in Resident Manager. This condop building does not require board approval and allows pets, unlimited subletting, pied-a-terres, co-purchasing, gifting, and parents buying for children.
