The southeast elevation is asymmetrical and made of tooled snecked sandstone rubble. It includes a central window and two smaller windows to the right on the principal floor, all featuring long and short dressings. There is a barred window located to the outer right of the basement.

The northeast elevation was not visible in 1997. The northwest elevation is also asymmetrical, constructed from tooled snecked sandstone rubble, with a window to the right of the principal floor that has long and short dressing.

Hooped railings line the principal elevation of the house, leading to the entrance.

The roof is covered with purple grey slate and has a piended design, with a rooflight at the apex, lead ridges, and cast iron rainwater goods.
