Blackbridge House is an early to mid-19th century building located at 1833 College Walk. It is rendered and features two storeys with three windows on the entrance front, which are sashes with glazing bars. A tall arched staircase window adds to its architectural interest. The house has a projecting plain porch and a hipped slate roof. There are later brick additions on the left side of the building.
