From its origin in 1939 when 'Tanglewood' controlled the 25 acres encompassing both sides of Contention Lane through to what is now Castlewood, Devonshire, Hickory, and Tanglewood Rds, this impressive stone Norman-style home retains its strong architectural appeal, now on 6 acres with commanding views of the surrounding woods and stream. Owned by the Heckscher family for almost 60 years until their departure in 1997, the home's interior appointments were influenced by the family?s passion for technology and the railroad industry. One of the first homes with a telephone, interior weather monitoring, recessed lighting, and in-wall speakers, its interior features dramatic detail: a center foyer stair rail formed from a railroad track, and pathway lights similar to those found in train cars of the time. These elements of original innovation and style remain in the home to this day. Following the Heckscher family's ownership, a generous guest house was added above the three+ car garage, featuring a bedroom, bath, kitchen, and fireplace; the space was further improved upon by the current stewards through a comprehensive, exciting interior renovation of the primary bedroom and bath, kitchen, and family bedroom as well as the additions of an exceptional seated bar with beer taps, additional light exposures, and access to the rear yard. Gardens surround a bluestone terrace made even more magical in the evening by overhead bistro lighting. A nature trail rings the property, providing a long walk through woods as well as glimpses of the property's specimen trees, including a hemlock gifted to the original owners by the Japanese government. Unlike so many from this era, this home enjoys high ceilings on its three finished levels with five (5) bedrooms and three (3) full baths found on the main home's second floor. Beautifully located within the TE school district and offering supreme tranquility yet only two turns from major roadways and premium shopping. The home is an oasis with a flexible floor plan able to accommodate many under one roof while still feeling intimate. An exceptional property.
