The building has three storeys and is nine windows wide. A central entrance with three arches is framed in stone, likely added in the early 20th century. The windows are square-headed and have architraves with pediments on the first floor. There is a bomb balcony on the first floor, along with a cornice and a parapet. The interior has not been inspected.

It experiences an average of 34 freeze-thaw cycles a year, more than 51% of listed buildings. Of these, 15 follow at least 1 mm of rain in the preceding 48 hours. Average temperatures at this location have risen by 0.3°C per decade since 1991.
