Magnificent - that's what 25 Paper Mill in Marlborough is! This stately Contemporary Colonial is located at the end of very private road and is situated on 3.59 wooded acres, so it's purely peaceful and tranquil. The home itself is like-new construction with a thoroughly delightful floor plan. The first floor features an expansive open-concept with the living room and chef's kitchen that is perfect for entertaining and family time. The two-story ceilings and windows allow for abundant light and there is also an office and a formal dining room on the first floor. Upstairs are the living quarters featuring a very impressive primary bedroom suite. The other three bedrooms are all very well-sized and each with ample closet space. The laundry is conveniently located upstairs as well. The basement is fully-finished with a large wet-bar that adds significant extra living area for your enjoyment, and there is a heated room that can be used as a 5th bedroom or office, as well. The back yard is large and level and can accommodate all types of outdoor activities and has an exquisite terraced stone patio. There is an oversized 3-car garage for the car enthusiast in you. The home is in exceptional mechanical and structural condition, with a newly-installed state-of-the-art geothermal system that is already saving hundreds of dollars each month that would otherwise have gone to Eversource and an oil company for cooling and heat.
