Description

Garreg Wen and the houses at 1-3 Tithebarn Street are late Georgian style, two-storey buildings featuring pebble-dashed walls and smooth-rendered dressings, including eared architraves. They have slate roofs with wide eaves, hipped to the left. Nos 1 and 3 are two-bay houses, with No 3 curving out to the right side next to No 5. Garreg Wen has a one-bay elevation facing Tithebarn Street, with its main entrance oriented towards Uxbridge Square.

No 1 has horned sash windows with six over one panes and a replaced door to the left. No 3 features a twelve-pane hornless sash window on the lower storey and a nine-pane window above, along with a half-lit panel door in the left-hand bay, set within an open gabled lattice-work wooden porch. Garreg Wen has four-pane sash windows on Tithebarn Street.

The front of Garreg Wen consists of three windows, with early 20th-century bay windows on the right and left, showcasing three-light wood mullioned and transomed windows. Between these bay windows is a first-floor balcony with an ironwork balustrade and a cross window. The doorway, which has a half-lit door, is located beneath the balcony. This group of buildings belongs together as part of the architectural context of 1-3 Tithebarn Street and Garreg Wen, Uxbridge Square.
