Corwen Manor (Old Workhouse)

Corwen Manor, originally a workhouse, is designed according to Benthamite principles, featuring a central octagonal tower that is illuminated from above and four radial wings. The building is primarily constructed of roughly coursed rubble, which is limewashed on the front elevations, and has slate roofs. The main gable facing the street is made of well-coursed stone with ashlar dressings, including a continuous string course. The principal entrance is located in this gable within a pedimented and slightly advanced central section, featuring a Doric portico in antis. The doorway is flanked by 9-pane sash windows, with additional 9 and 12-pane sash windows on either side of the pediment, which also has a tripartite window in its upper storey. Similar sash windows are found in the return elevations of this block.

The longest wings extend east and west from the central octagon, which is visually expressed by slayed walls at each of the four angles between the radial wings. These walls contain wide segmentally arched cast-iron small-paned windows, although some have been replaced by 4-pane sashes. The central octagon is topped with a glazed lantern and a high wooden cupola. Each long wing ends in a slightly advanced pavilion with a hipped roof; these were originally designed with three-window ranges, and some original round-arched windows with cast iron fixed lights remain, though many have been replaced by wider 4-pane sashes. At the inner angle of the wings and the central octagon, each wing steps out slightly and features a round-arched doorway with cast iron glazing above.

On the rear wing, each side has paired 4-pane sash windows on the ground floor and a doorway with a round-arched overlight in the re-entrant angle. While some original window openings are still intact, many have been replaced with wider windows. The original layout is partially preserved, with notable original details including a divided staircase in the entrance block, which features cast-iron balusters and a swept rail. The large rooms on each floor in the east wing may have served as former workrooms, while accommodation is primarily located in the west wing, where smaller rooms open off a central corridor.
