With gently sculpted curved walls and ceilings, up-lit gallery lighting, and sublime open spaces, this completely redesigned residence offers what so few can: the opportunity to live and entertain in a one-of-a-kind piece of art. Reconfigured to maximize natural light, drama, and function, the space is a breath of fresh air - the perfect backdrop to your life, your collection, and your gatherings. A stunning entrance organically flows into the expansive living and dining rooms with magnificent terrazzo floors, walls of glass into the trees overlooking Oak Street beach, and floor-to-ceiling frosted glass doors opening to a separate family room/library. The refined kitchen - with flat-fronted cabinets, integrated appliances, an island with seating, and a large walk-in pantry - opens to the terrace in front and to the separate laundry/utility room in the back. A wonderful primary suite has an enormous outfitted walk-in closet and bath swathed in slabs of travertine. Two additional bedrooms offer flexibility to your lifestyle and needs. The "D" tier is the best in the building: the most square footage and the best orientation, looking north. Move in and enjoy this architectural masterpiece in Chicago's best full-service building w/24-hour doorstaff, onsite management, large indoor pool, gorgeous ballroom, extensive workout facilities, and huge common roof terraces.
