Presenting a truly once-in-a-generation opportunity to create an extraordinary full-floor penthouse residence atop the iconic London Terrace Towers. Offered together, Penthouse A and Penthouse B provide a rare full-floor presence and the opportunity to seamlessly combine two exceptional homes into a bespoke 4+ bedroom penthouse oasis, crowned by expansive wraparound terraces with breathtaking 360-degree skyline views, subject to review by the purchaser’s architect and Board approval. Rarely does a residence of this scale become available, offering the coveted combination of full-floor privacy, exceptional outdoor living, and panoramic exposures in one of Chelsea’s most iconic prewar buildings. The combined offering allows for the creation of a grand-scale home that is both elegant and highly functional, with the privacy and exclusivity typically reserved for the city’s finest penthouses. Alternatively, the residences may remain separate, preserving two beautifully appointed two-bedroom, two-bathroom penthouses ideal for guests, extended family, live-work flexibility, or any lifestyle that benefits from privacy while maintaining close connection. Designed by the renowned architectural firm Farrar & Watmough and completed in 1930, London Terrace Towers stands among Chelsea’s most distinguished prewar cooperatives. Residents enjoy an exceptional collection of amenities, including a state-of-the-art fitness center, heated indoor swimming pool, sauna, steam room, beautifully landscaped private gardens, rooftop deck, bicycle storage, laundry facilities, and an on-site parking garage. Perfectly positioned alongside the High Line and moments from Chelsea’s celebrated galleries, acclaimed dining destinations, cultural institutions, and vibrant theater scene, this remarkable offering presents a rare opportunity to craft a trophy penthouse residence defined by iconic views, expansive outdoor living, full-floor privacy, architectural pedigree, and limitless potential. Penthouse A is available exclusively in conjunction with Penthouse B and is not being offered separately.
