Welcome to the Solomon Thatcher Jr. Home, one of the first and finest homes built in River Forest. This home was built on 516 and 518 Keystone Avenue. Keystone Avenue is affectionately referred to as "The Street of Dreams" with some of the deepest parkways, setbacks, and yards up to 235' deep. A rare opportunity to own a very distinctive home situated one block from beautiful Keystone Park, and the River Forest Metra train station. This impressive three story home features a Mansard roof, elongated windows, and a welcoming porch and veranda. Solomon built this home with thoughtful, hand crafted millwork. He was a builder that also owned a sawmill which accounts for the incredible selection and execution of the woodwork displayed throughout the home. The home is designed around a grand central foyer with soaring ceilings, 8' pocket doors and a transom of french panes. The foyer and the first floor rooms are filled with art and stained glass, fireplaces, some original gas light sconces, hand carved woodwork, wainscoting, beamed ceilings and more. Moving through the grand foyer is the intimate dining room showcasing warm walnut wainscoting and breathtaking crown moldings found frequently in great Chicago architecture of this period. Off the dining room is a breakfast room flooded with light and panoramic views of the expansive yard and mature trees. The chef's kitchen features custom cabinetry, granite counter tops, an island with seating for six, high-end stainless steel appliances including a professional 48" oven/range, two refrigerators and two dishwashers for quick clean up. Off of the kitchen is a convenient mudroom that includes first floor laundry. This awesome kitchen was selected for the annual Parenthesis Kitchen walk. The home was also featured as an ASID showcase home, a Wright Plus house walk home and was on the 2022 River Forest Historic Homes Tour. The second floor includes a magnificent hallway with a striking floor to ceiling mahogany trimmed mirror. There are 4 bedrooms, 3 baths and a sunroom on the second floor. The Primary suite includes a fireplace, sitting area, walk-in closet, luxurious spa bath, separate shower and elegant double sink vanity. Third floor includes a game room, an office, 3 bedrooms and a full bath. There is a Coach House above the garage that is freshly painted and includes one bedroom, a family room, kitchen and a full bath. This is your opportunity to live in a wonderful home in a fabulous location on one of the largest lots in River Forest.
