From Surveys Completed 2011-2012 by the Lenox Historical Commission


This is a 2-story, 5-bay, stone and wood framed house built in the Tudor Revival or English Cottage style. It is oriented to the south, with a hill rising up behind it. It is clad with stone and stucco with some half-timbering. It has a gable roof with asphalt shingles; it extends down to the top of the first floor in the rear. There are six chimneys, most of them brick, with corbelling and flared tops. However, the exposed front wall chimney is of stone a typical feature of the Tudor Revival style. The front façade is distinguished by three pavilions, all with steeply pitched front gable roofs; the center one is smallest but is stone clad, features a king post at its peak, and contains the Tudor-arched entrance. The front door is recessed, creating a shallow entry porch. Above the door is a set of three casement windows. The first floor also has a group of three windows in the bay left of the entrance pavilion and a pair of windows in the bay to its right. Paired windows are above these. A large brick interior chimney is in this section of the house. There is a right side ell with the basement exposed at its right side due to the slope of the site. Above, on the front, the stuccoed second story overhangs the first floor and there is a brick end-wall chimney. Around the right corner is a balcony with an X-patterned railing. A set of three windows is on the first floor front facade and paired windows are on its second. A newer 1-story hipped roof ell is off the left end of the house. A brick end-wall chimney is located between it and the main section. There are four gabled dormers on the rear. Most of the windows are intact 4-o-4 double hung sashes. The foundation is stone. A detached, hipped- roof, 2-stall garage is located to the right (east) of the house. There is an in-ground swimming pool in the rear yard, separated from the house by a stand of coniferous trees. A circle driveway centered on the front entrance is fronted by a stone wall. A long driveway off Under Mountain road connects with it from the east.
