As originally built the structure was a relatively small two-story, L-shaped administrative building with a stone first floor and a frame second floor. When it was converted to a residence in 1931 it was enlarged in a sympathetic manner, retaining its original design vocabulary. The main living quarters are on the upper level, with eight rooms including the living room, dining room, kitchen, bedrooms and bathrooms, with stone fireplaces in the dining and living rooms. The main entrance is from a porch off the living room. The downstairs features a family room with another stone fireplace, formerly the visitor information office. There remainder of the lower level is occupied by a variety of rooms and winding corridors that connect to a two-car garage.
