A property without equal: the most significant single-family townhouse ever offered for sale on the Upper West Side. Just off of Central Park, 48-50 West 69th Street is a residence that evokes a kind of scale, drama, and attention to detail not found since the Gilded Age, when palatial homes lined the neighborhood s avenues and preceded today s apartment buildings. Years of careful planning by Fradkin & McAlpin Architects and MDesign London has resulted in a truly extraordinary home spanning 41.5 feet wide and 19,600 square feet of interior space, with multiple oversized outdoor entertaining areas throughout. A post-tensioned limestone floating staircase is the architectural through-line that connects all eight levels and leads you to the home s innumerable features. The parlor level boasts a 38-foot wide, double height living room with 24-foot ceilings and dual opposing wood-burning fireplaces, as well as a window-wrapped dining room with double-height sitting area and skylight. The garden level is anchored by an incredible indoor/outdoor health and wellness space including a 55-foot indoor lap pool, jacuzzi, fitness center and yoga space, all wrapped in full-height sliding glass walls which open to the tranquil south-facing garden, making a truly one-of-a-kind experience. The full floor primary suite measures over 2,000 square feet with a wood burning fireplace, dual baths and dressing rooms, private study, and an expansive south-facing terrace off the bed chamber. The residence s penthouse lounge is the sun-flooded jewel box atop the home, with a wraparound terrace boasting southern views onto Billionaire s Row, an oversized wet bar, and an immense skylight. Multiple guest bedroom suites, staff space and ample amenity spaces are all serviced by a high-speed commercial-grade elevator. Rarely have homes of this prominence been created, and even fewer have ever become available for sale. 48-50 West 69th Street stands as the modern-day epitome of the city s grandest historic residences, ushering in a new chapter in the story of the neighborhood s single-family properties for one discerning purchaser.
