A rare opportunity arises to own a singular architectural masterpiece designed and built in 1979 by noted architect, Roy Binkley for his own family. Sited on 2.8 privileged acres encompassing the historic Stanley Field estate garden and croquet field on Lake Michigan, this iconic property stands as an ode to modernism and featured in Architectural Digest. The home was inspired by the cubic simplicity of Mies van der Rohe, under whom Binkley studied. A dynamic interplay between hard lines and soft curves, openness and enclosure, and old and new unfolds throughout the circular floor plan. Unique architectural details from a floating staircase and limestone floors on the main level to double-dome skylights create visual interest. Soaring ceilings and expansive walls of glass blur the lines between interior and exterior, offering panoramic vistas of the lake from nearly every vantage point. Each level of the three-story home presents a separate stage and a different scene. Mature trees and meticulous landscaping further enhance the feeling of a secluded, private lakefront sanctuary. Having passed through only two sets of discerning owners, the home has been meticulously cared for since its inception. Recent updates include a thoughtful conversion of the exterior to stucco in 2018 and a complete roof replacement in 2020. Conscientious restoration and renovation have ensured every element reflects the spirit of contemporary living. The kitchen, primary suite, second-floor hall bath, and laundry have all been modernized with an astute eye for detail. On the third floor, the autonomous treetop suite, once the architect's studio, underwent a clever transformation into a spacious fourth bedroom suite complete with closet and en-suite bath. From here, enjoy panoramic views of Lake Michigan from wide curved picture window. Joan Binkley's former artist studio now offers a welcoming family room. Attached to the 3-car garage is a separate garden room with sink and full bath, which could be a fifth bedroom with ensuite bath perfect for guests, in-laws or office. Internationally renowned landscape architect Doug Hoerr further elevated the property in 2001 with a redesigned hardscape and garden, including a large limestone terrace mirroring the home's interior. Additional features include four independently controlled HVAC zones for comfort. An unfinished lower level provides ample storage, including a wine cellar and a cedar closet. Revetment work in the early 2000s and further stabilization efforts involving railroad ties and partial stairs in 2016 ensure continued peace of mind for the next owner. Additionally, a permanent easement exists on the property, shared with two neighboring homes, for access to the north side of the property. This exceptional offering presents an unparalleled opportunity to own a piece of architectural history in Lake Bluff. Roy Binkley's modernist masterpiece, nestled amidst the natural beauty of Lake Michigan, awaits a discerning owner who appreciates timeless design and breathtaking surroundings.
