2, Castle Hill

No. 2 Castle Hill is a house that has been converted into offices. It was built in the mid-18th century and has been altered in the 19th and 20th centuries. The building is constructed of coursed squared sandstone with ashlar dressings and features a slate roof that is gabled on the left and hipped on the right, along with brick chimneys. It has a rectangular plan and the main facade consists of three storeys and five bays. On the right side, facing down Church Street, there is a return facade with three bays above a cellar, which includes a door on the left and a blocked window on the right. Both facades have raised quoins, plain surrounds for all openings, and an eaves cornice. The windows are sashed and do not have glazing bars. The central doorway in the five-bay facade is recessed and accessed by five stone steps with iron handrails; the reveals of the doorway feature raised and fielded panels. The rear wall includes a central full-height staircase window.

Inside, the room at the right-hand end of the ground floor is fully panelled, with a moulded cornice and raised and fielded panels both above and below a dado rail, as well as a shouldered fireplace surround. An upper room contains a stone fireplace with a raised keystone. The full-height dogleg staircase features an open string, carved scrolled brackets, two turned balusters per tread, and a ramped and moulded handrail with a wreathed curtail, although the topmost flights have a closed string with less decoration.
