The north wing. a three-story, nine-bay U-shaped structure faced in granite veneer in a random ashlar pattern over load-bearing rubble masonry. The central block has a hipped roof, with corbeled crenelated parapets on the projecting sections, with a simple cornice on the non-projecting sections. Crenelated polygonal chimneys rise from the southeast side of the main block. The two wings, which project from the ends of the northwest (front) facade, had mansard roofs. At the center of the front facade is the main entrance. It has a porch open on three sides, oriel window above and projecting corbeled feature above the roofline. A wide pointed arch holds the main entrance. Though designed in the Gothic Revival style, all of the windows on the third floor have pointed arches rather than curves, unusual for that architectural style.
