Two wings have been added, including a breathtaking three-room master suite. The large master bedroom has a walk-in closet, window seats, and a working fireplace. It sits between a full bath with a two-person Jacuzzi tub and a two-story library with solid cherry paneling and a wooden corkscrew stairwell made of walnut that leads to a loft office.

The kitchen is a long rectangle with exposed beams, red birch cabinets, a working Rumford fireplace, stainless steel appliances, and a dining area.

The third wing is a light-splashed family room with cathedral ceiling, exposed beams, and Palladian door leading to the backyard.

There is a three-season room, in tongue-and-groove cedar, overlooking a desk made of ash. The second-floor bedrooms, three in all, have wide planked flooring, ample closets, and access to the full bath with a shower.

The house is nestled deep in the 1.76-acre lot, which also includes an in-ground pool shaped like a mountain lake fed by a “waterfall’’ of filtered water. There is a separate built-in hot tub. There is a three-car garage. The roof is fire resistant cedar shingling.

Arlene Santangelo of Keller Williams in Andover is holding an open house on Sept. 11 from 1 p.m. to 3 p.m.
