551 West 21st Street's Penthouse C embodies the distinctive creative process of Foster + Partners, one of the world's most prestigious architecture practices. Winner of the Pritzker Architecture Prize, Foster + Partners is renowned for their holistic approach to design, influenced by the material and transcendent needs of the people, always with utmost consideration of the culture and context in which they build.

Rising over 200 feet above the West Chelsea arts district, Foster + Partner's magnificent 6,137 square foot Penthouse C offers column-free interiors and panoramic views, particularly from the nearly 2,000 square feet of private outdoor space. With dedicated elevator access through both the entertaining and sleeping areas of the home, Penthouse C delivers incredible scale and perpetually vivid sunrise-to-sunset views over Manhattan and the Hudson River.

Spanning the entire eighteenth floor, this extraordinary home is defined by a classic floor plan, akin to those of a bygone era, reinterpreted with a modernist sensibility and an unprecedented attention to detail. Direct elevator access into an elegant and gracious vestibule with custom millwork and cove lighting leads one through the stately center gallery that delineates the entertaining rooms from the private living quarters. The vast corner entertainment wing is comprised of an impressive grand room and club space separated by a central double-sided wood burning fireplace. A fifty-seven-foot-long terrace wraps the entire northwest corner of the grand room, while a thirty-four-foot-long loggia lines the western perimeter, revealing coveted views over New York City's most acclaimed landmarks and the Hudson River. A thirty-five-foot corner dining room off the center library invites lively dinner parties and entertaining. Luminous metal reveals throughout perfectly frame each window and provide perimeter seating for quiet contemplation and breathtaking views of the ever-changing sky.

A thirty-foot-long chef's kitchen designed by Foster + Partners and produced by Molteni & C-Dada includes beveled Blanco de Macael marble countertops with matching backsplash and natural stained oak cabinetry. Top-of-the-line appliances including a Gaggenau cooktop, barbeque grill and Teppanyaki grill with two Best Range extraction hoods, Miele integrated coffee machine and warming drawers, and integrated Fisher & Paykel cooling drawers equip this sunlit, south-facing kitchen. With a separate butler's pantry containing additional rows of refrigeration (including two built-in thirty-inch Sub-Zero wine coolers providing storage for 300 bottles), the Penthouse kitchen permits lively dinner parties and intimate family gatherings. The nearly 1,000 square foot corner master suite is extended by its own fifty-three-foot-long terrace running the entire eastern perimeter and an additional thirty-three-foot-long loggia that opens to the warm southern horizon. The exceedingly luxurious corner master bathroom, across from a stunningly considered dressing room with direct terrace access, features enormous windows with northern city and river views, a bespoke vanity, separate enclosed shower and water closet and a freestanding bathtub. Two additional large bedrooms have en-suite bathrooms with Travertino stone tile floors, custom designed cabinets with beveled edges, and Dornbracht fixtures.

Eleven-and-a-half-foot ceilings, solid white oak herringbone floors and sets of nine-foot-high double doors with deep wood thresholds are among the many details that exemplify the richmateriality infused into this Foster + Partners home. The substantial outdoor areas of Penthouse C are seamlessly married to the interiors through expansive ten-foot-high tempered glass doors, and are fully equipped with electricity, plumbing and lighting.
