Overview of 551W21 at 551 West 21st Street

551 West 21st Street is a 19-story, 44-unit luxury condominium completed in 2015, designed by Pritzker Prize-winning architect Norman Foster and Foster + Partners - their first residential project in the US. Developed by Scott Resnick of SR Capital and GTIS Partners, with Beyer Blinder Belle as associate architect, the building stands as an architectural masterpiece in West Chelsea. The structure features a striking white precast concrete and polished brass façade with distinctive window treatments combining gold and black metal frames.

The building's dramatic entrance includes a gated drive court surrounded by a 20-foot green wall and leads to a 34-foot-high double-height lobby with a prismatic glass wall and grand chandelier. Residences feature 11-foot ceilings, French-inspired oak herringbone floors, custom millwork, and floor-to-ceiling windows with deep façade reveals for perimeter seating. Kitchens showcase Blanco de Macael marble countertops, natural stained oak cabinetry, and premium appliances from Sub-Zero, Miele, and Gaggenau.

The three full-floor penthouses span approximately 6,200 square feet each with 12-foot ceilings and 360-degree views. The top penthouse includes over 4,000 square feet of outdoor space featuring a 61-foot-long swimming pool - the largest private outdoor pool in New York City. All penthouses include separate elevator entrances for entertaining and private quarters, wood-burning fireplaces, and sophisticated climate control systems.

Amenities include 24-hour doorman, concierge, porter and valet services, a state-of-the-art fitness center with spa facilities, yoga room, residents' lounge with fireplace and catering kitchen, children's playroom, bike storage, and a dedicated service entrance. The building also offers on-site parking.

Located at 551 West 21st Street, the building sits half a block from the High Line and across from Chelsea Piers in the heart of West Chelsea's gallery district. The neighborhood offers easy access to the Meatpacking District, West Village, Hudson Yards, and numerous acclaimed restaurants and cultural attractions.

The building represents Foster's continued architectural innovation in New York, following his other notable projects like the Hearst Tower and 50 United Nations Plaza. Its sophisticated design and attention to detail have established it as one of West Chelsea's most prestigious addresses, offering residents an exceptional living experience with stunning Hudson River and city views.
