23 Segontium Terrace

23 Segontium Terrace is part of a late Georgian terrace consisting of seven three-storey, two-bay houses with basements. The houses feature rendered fronts, with some retaining original moulded architraves around the windows and exposed rubble stone walls at the rear. The slate roofs are sloped towards the back, and each house has a brick or roughcast chimney stack on the right side. The doorways are located on the left sides and are accessed by steps. Many houses still have their original iron railings on dwarf stone walls, although the gates to the basement steps have been replaced. The railings are adorned with trident finials and urn finials on the stanchions.

In addition, 23 Segontium Terrace has a roughcast front with replaced windows in the original openings and a doorway that features an added flat-roofed porch. The forecourt railings have been removed.
