This is a rare opportunity to own a truly distinctive corner duplex penthouse in one of the city's most coveted locations. Originally created as the developer's own residence, this architecturally distinctive duplex penthouse offers nearly 2,500 square feet of living space in the heart of the Gold Coast. Flooded with natural light from dramatic floor-to-ceiling windows, this home showcases sweeping skyline and lake views from nearly every angle. The thoughtfully renovated kitchen is equipped with a Bosch Benchmark induction cooktop and range, while a convenient in-unit laundry closet includes a washer and dryer. A striking wide spiral staircase anchors the space as an amazing architectural feature, connecting expansive living and dining areas ideal for both everyday living and entertaining. Primary en-suite bathroom features a massive custom shower with Phillips hue LED lights. Additional highlights include a versatile den or sunroom, abundant closet space, and Lutron lighting throughout, adding both comfort and sophistication. An additional flexible space can be found off the second bedroom- currently used an office, but could easily be converted into a walk-in closet. This special residence was personally constructed for Robert Edelman, the owner/developer of the building, back in 1971. Residents of 100 E Walton enjoy full-service amenities including 24-hour door staff, an attached parking garage, gorgeous rooftop pool, fitness center, and on-site management.
