Offered for the first time, this one-owner custom home reflects an exceptional level of care and craftsmanship in one of Helena's most desirable Upper East Side locations. From the remarkably preserved interiors to the beautifully maintained grounds, 809 Tower Street has been cared for with a level of pride that is increasingly hard to find. The home offers 3 bedrooms, 2.5 bathrooms, a spacious main living area, two fireplaces, and a large upstairs bonus/storage room. The well-planned layout provides comfortable spaces for everyday living and entertaining, while a whole-house air exchange system adds year-round comfort. Significant improvements include a new roof, windows, and appliances. Outside, the private, fully fenced backyard offers mature landscaping and a peaceful setting for relaxing or entertaining. An oversized garage provides generous parking, workspace, and storage. Exceptionally clean, carefully maintained, and filled with the quality of a true custom home, 809 Tower Street presents a rare opportunity to own a property that has been loved and preserved by the same owner since it was built.
