• 5 beds |
• 4 baths |
• 4,500 sqft

Property Description

The Spring House begins with one of its most compelling features: an exceptional detached guest house with two rooms, a full bath, loft area, two walk in closets, and a three car garage. Ideal for a mother daughter arrangement, extended space or guest accommodations, it can also become a home office, music studio, podcast studio, art studio, private gym or wellness retreat. From there, the property unfolds across three peaceful acres on one of Tewksbury's most coveted country roads, surrounded by preserved farmland where some days more horses pass than cars. The main residence offers five bedrooms and four baths, blending timeless character with modern comfort, including a primary suite with dry and steam saunas. Cold Brook runs along the western edge beside a historic 1800s cobblestone bridge, while three water features, a large fire pit and a stone wood burning oven invite time outdoors. A separate container structure creates yet another flexible retreat, all within a private country estate surrounded by protected land and located minutes from top rated schools, scenic trails and New York City.
