Situated on a prestigious private lane in East Highland Park, this rare lakefront offering is a Mid-Century Modern masterpiece. Designed in 1957 by renowned architect Henry L. Newhouse II for Irving B. Harris, Chicago Philanthropist, this 10,000-square-foot contemporary residence sits on nearly two acres of lush grounds with magnificent, unobstructed views of Lake Michigan. Experience the ultimate wow factor as you enter the dramatic foyer and take in the breathtaking vista. The interior features large expanses of glass and natural light, offering a flexible floor plan that flows effortlessly for entertaining and everyday living. An exquisite foyer leads to custom beveled, imported French Limestone floors and dramatic floor-to-ceiling windows that frame the water. With minimalistic aesthetic, the Chef's Eat-In Kitchen is finished with custom black walnut cabinetry, a wall of granite, gourmet appliances, and a sleek gas fireplace. The home's expansive footprint includes a main floor Primary Bedroom Suite with a secondary Primary Suite on the 2nd level and seven additional Ensuite Bedrooms, providing unparalleled space and privacy. Despite significant renovation since construction, the home still retains the core architectural integrity and mid century character established by Newhouse. For wellness and recreation, an Indoor Pool Pavilion features a Dectron temperature-controlled system, a retractable clerestory roof, a steam room, and a dedicated second kitchen equipped with Viking appliances. Outside, the tranquility of the lakefront setting takes center stage. A sparkling Outdoor Pool overlooks the water, while a private tram and stairs lead down to 150 feet of secluded beach. This is a unique opportunity to own a significant piece of architectural history with unlimited potential on the shores of Lake Michigan!
