Rare opportunity to own a piece of St. Louis architectural history with an extraordinary private lakefront lifestyle. Designed and built in 1974 by renowned St. Louis architect Tom Hall as his personal residence, this one-of-a-kind Mid-Century Modern has been extensively renovated while thoughtfully preserving Hall's original design. Set on 3 wooded acres in gated Arrowhead Estates, the property overlooks a private, spring-fed lake with its own dock. Walls of windows, skylights and Hall's signature circular windows fill the house with natural light and connect nearly every space to the surrounding woods and water. The open floor plan features three fireplaces, a dramatic Atrium, sunken conversation Den and custom wood screens inspired by the surrounding trees. Hall's original office—with private entrance, half bath and walls displaying his architectural blueprints—remains an extraordinary piece of the home's history. The main-floor primary suite offers a fireplace, private lake-view balcony, ensuite remodeled bath and large walk-in closet with island. The kitchen and dining areas flow into the spacious family room with a floor-to-ceiling stone fireplace and sliding doors opening to lakeside decks. Upstairs are three generous sized bedrooms and beautifully remodeled baths. Extensive improvements include a new roof, remodeled bathrooms and kitchen, plus significant updates to major systems—including electrical, water heater, filtration and extensive foam insulation—along with substantial exterior, drainage and landscaping improvements. See supplements for the complete improvement list. Outside, 3 private wooded acres and a dock on the approximately 5-acre spring-fed lake create an exceptional setting for fishing, kayaking, paddle-boarding or simply enjoying the wildlife and views. Arrowhead Estates also offers tennis courts and a gated setting. Enjoy the feeling of a private retreat while remaining just minutes from Chesterfield Valley shopping, dining and entertainment, The District, The Factory, Faust Park/Butterfly House, groceries and Highway 40. Architectural history, thoughtful renovation, privacy and a private lake—this is a property that simply cannot be replicated. This is a home that truly needs to be seen to be appreciated.
