A unique opportunity to own a landmark from one of America's Industrial Revolution pioneers - the Whitin Lasell Manor (circa 1890) built by former industrialist Chester Whitin Lasell. The mansion's "main house" offers 3-floors of living space w/additional basement storage & utility rooms. The 1st floor has been carefully restored and provides 6 separate entertaining areas (lobby/reception, music room/auditorium, living room/library, billiards room, solarium & dining room). Original period details throughout including wood carvings, pocket doors, stained glass windows & approx 15 fireplaces w/decorative mantels. While the use & occupancy of this historic property has changed over the years the current 20, 000+/- SqFt floor-plan includes approx 23-BDs, 9-BAs & 4 1/2-BAs. The former family residence, most recently used as a retreat & conference center, is ripe with development opportunities: hospitality-related ventures, wellness & healthcare or facilities for education just to name a few.
