Timeless architecture, extraordinary scale, and an exceptional East Lake Forest lifestyle come together at 400 Washington Road. Set on a beautifully landscaped acre just blocks from Lake Michigan, Lake Forest Beach, historic Market Square, and Metra, this impressive 6-bedroom, 5.4-bath Georgian offers the rare combination of architectural distinction, beautifully proportioned living spaces, and remarkable flexibility for today's lifestyle. Originally designed by renowned architect Henry Ives Cobb, the home has been thoughtfully updated and meticulously maintained while preserving the craftsmanship, character, and sense of permanence that make it so special. Significant recent investment has addressed not only the home's visible finishes, but also many of the important behind-the-scenes elements, giving the next owner the benefit of a historic residence that has been carefully stewarded for modern living. A stately circular drive winds beneath magnificent white oak trees, creating an unforgettable approach to the home's iconic Georgian facade. Inside, approximately 6,873 square feet across the first and second floors provides an exceptional sense of space without sacrificing warmth or livability. Gracious formal rooms flow comfortably into the spaces where life happens every day, including an inviting family room, handsome private office with fireplace, and an updated kitchen featuring premium Sub-Zero and Miele appliances. Fresh, beautifully maintained interiors and thoughtfully restored architectural details allow the home's original character to shine while feeling polished and move-in ready. Upstairs, four spacious ensuite bedrooms provide privacy and comfort, along with a generous second-floor laundry room. One of the home's most compelling features is its third level, an additional approximately 2,100 square feet of above-grade living space filled with natural light. With additional bedrooms, a study, media room, recreation space, and kitchenette, this level offers incredible possibilities for a home office suite, children's hangout, guest quarters, au pair accommodations, creative studio, or private space for extended family. The basement adds a fitness area, extensive storage, a climate-controlled 2,000-bottle wine cellar. Outdoor living is equally inviting. A screened porch and expansive stone terrace overlook the beautifully landscaped grounds, offering effortless spaces for summer dinners, weekend gatherings, or simply enjoying the privacy and beauty of the property. With substantial recent improvements including new 2024 roof, attentive maintenance, and enduring architectural quality, 400 Washington Road offers something increasingly rare: a distinguished historic home that feels both established and exceptionally well cared for. Grand yet comfortable, historic yet highly functional, it is a remarkable opportunity in one of Lake Forest's most desirable locations to make new memories.
