Its building complex is located near the property's southeastern corner, on the west side of the road, at one of its highest points.

The main house is a 2+1⁄2-story wood-frame I-house, with a side-gable roof, end chimneys, clapboard siding, and a marble block foundation.

The main facade is five bays wide, with a central entry with marble floor sheltered by a gabled porch, and a Palladian window above.

The interior retains original features from the early 19th century, including hand-forged hinges and latches made by the building's most prominent resident, Jonas Galusha.

The front part of the house was built in 1805, supposedly to a design suggested by local master builder Lavius Fillmore.
