Description

Nos. 2 and 3 Castle Square is a house from the early 19th century that has been divided into two and converted into offices. The building is finished in stucco and has a tiled roof. It stands three storeys tall with dormers above a basement. The original structure features a three-window range, with segmental bays on either side of the central window range, each containing tripartite windows. All the windows have flat arches. The building has a parapet with coping and three flat-arched dormers that have catslide roofs. There are stacks located on the party walls. The interior has not been inspected. This building is included for its group value, as it forms part of a group with Nos. 1 & 1A and Nos. 2-7.
