Treasurer's House

The Treasurer's House is a two-storey building constructed from roughcast rubble stone. Originally designed with three windows, it was extended to four in the later 19th century, matching the original style. A colourwashed rubble stone service wing is located to the southwest. The main house features a slate roof with end stacks and a ridge stack at the original end wall. The original three-bay front has tripartite 4-12-4 pane sashes in the outer bays and a 20-pane sash in the centre, positioned above a flush-panelled four-panel door set in a painted timber doorcase with a shallow open pediment on elongated brackets. An eroded stone moulded course at the eaves, which may have originally been cyma-moulded, could be a remnant of an older building. The added eastern bay from the 19th century has similar tripartite sashes on each floor. The rear includes a 12-pane stair light and 4-pane sashes.

At the western end, there is a low one and a half storey cottage or service range known as Treasury Cottage, built from colourwashed rubble stone. This features a central ledged door with an overlight, a 6-pane window to the right, and two first-floor 9-pane sashes that break the eaves, with the left one possibly added later or renewed.

Historical records, including Joseph Lord's 1720 map, indicate that a northern wing of the medieval Treasurer's House existed on this site, along with a smaller western section where the service range is now located. However, the interiors currently show no signs of earlier structures, except for a unique feature: a long corridor that runs the length of the rear wall, as marked on the 1720 map. The building also contains an early 19th-century staircase with a circular newel and one room featuring a 19th-century iron grate in a plain wood surround.
