Introducing a towering architectural masterpeice in the heart of Chicago's Gold Coast, a David Adler-designed duplex home 2 blocks from the lake. As you step off the elevator, you are immediately transported into what feels like a Parisian apartment. Adler, a proponent of Paris's Ecole des Beaux-Arts, imbued the penthouse with the elegant spirit of a "single-family home in the sky". Classical symmetry, superb proportions, and resplendent architectural detailing throughout define its nearly 8,000 square feet, providing an unforgettable backdrop for breathtaking views in every direction. Three outdoor terraces further captivate with unobstructed city views. This home, a true and unique work of art, is ideal for both day-to-day living and grand entertaining. A grand checkered-floored entrance hall guides you towards two magnificent principal spaces: a gracious living room and an expansive dining room. The grandeur of the main floor unfolds before your eyes as natural light cascades through the windows, casting an ethereal glow upon the surroundings. Spanning over sixty feet, the living room boasts three distinct seating areas, where you can recline and revel in the panoramic city and lake views. An elegant library, adorned with endless built-ins, offers a space for quieter moments. Each space exudes a sense of gravitas, underscored by arched doorways and windows, meticulously crafted custom millwork, antique fireplaces, parquet, and herringbone hardwood flooring, and other bespoke details that define an Adler masterpiece. Ascending the marble staircase, you arrive at the custom-designed kitchen, uniquely arranged in a half-moon shape with stone counters, a La Cornue range, top-of-the-line appliances, generous storage, and a well-appointed butler's pantry. A total of six bedrooms are found throughout the home, with the primary suite serving as the piece de resistance featuring a private office and dressing room, fireplace, dual bathrooms, and meticulously designed custom closets. Four additional spacious bedrooms await upstairs, each offering respite and tranquility. Many other unique attributes, such as a 7-zone HVAC system that is independent of all other HVAC systems within the building, contribute to the rare single-family home atmosphere that permeates this residence. Nestled on one of the most coveted streets and set atop one of the most celebrated historic condominium buildings in the Gold Coast, this extraordinary penthouse offers its next owner all of the accouterments of unparalleled luxury living in the city. Enjoy convenient parking and a premier location near the best shopping, restaurants, esteemed public and private schools, and majestic Lake Michigan. A residence of such distinction and prestige does not come along often! **This is an as-is deal. Please refer to broker remarks for more information.
