Property Description

The Koenig House - Designed by Winston Elting Architects, Chicago (1963) Offered on the open market for the first time since it was commissioned in 1963, The Koenig House is a rare opportunity to own an architecturally significant five-bedroom, four-bath Mid-Century Modern residence designed by Winston Elting Architects of Chicago for Dr. Harry and Debbie Koenig. Completed in 1964, the home was purchased directly from the original owners in 2021 through a private sale and has never before been publicly offered. Nestled on a beautifully wooded lot and a half in Ishpeming's desirable 8th Addition, the property offers an exceptional blend of privacy and convenience. Just 20 minutes from downtown Marquette via US-41 and within walking distance of Birchview Elementary School, the home is surrounded by mature trees with direct access to the groomed cross-country ski and mountain biking trails of the Al Quaal Recreation Area. Step outside to miles of year-round trails leading to Teal Lake, creating an unmatched Upper Peninsula lifestyle. Designed to embrace its natural surroundings, The Koenig House showcases the clean lines, warm materials, and seamless indoor-outdoor connection that define classic Mid-Century Modern architecture. Soaring vaulted ceilings, a dramatic floor-to-ceiling brick gas fireplace, an open catwalk, and a spacious loft create bright, inviting living spaces. Extensive built-in cabinetry and custom closets reflect the thoughtful craftsmanship and functional design of the era. A detached two-story, two-car garage includes a heated upper-level workshop and traditional sauna, offering outstanding space for hobbies, projects, storage, or outdoor gear. The current owners have made significant investments to preserve the home's architectural integrity while improving long-term performance. Updates include new Marvin windows on the east elevation; new cedar siding with upgraded OSB sheathing and Rockwool insulation on the east and north elevations; professionally sealed foundation walls with new French drains; a fully encapsulated and insulated crawl space by K2; a new sewer line from the street to the home (2025); plus a new concrete driveway and garage door. Several bedrooms and bathrooms have also been tastefully updated while respecting the home's original design. For buyers who appreciate exceptional architecture, additional custom-milled cedar siding is available and negotiable with the sale, providing valuable material for future preservation. More than simply a home, The Koenig House is an important piece of Upper Peninsula architectural history—a meticulously maintained Mid-Century Modern residence where timeless design, exceptional craftsmanship, and an extraordinary natural setting come together. Opportunities to acquire homes of this caliber are exceptionally rare.
