20, Treeton Road

No 20 Treeton Road is a former police station and lock-up, now a private house, built in 1843 by H F Lockwood of Hull. The building is constructed of brick in Flemish bond with stone dressings and has a Welsh slate roof. It features a main house with three bays, where the central bay projects forward and extends into a rear wing. There is an additional outhouse set back to the left and a small bay slightly set back to the right.

The building is two storeys high, with one window on the first floor. It has a plinth and steps leading to a central round-arched panelled door, which is framed by a moulded architrave and flanked by fixed windows in eared architraves. The outer bays contain four-pane sash windows in eared architraves, set on stone sills supported by brackets. The outhouse on the left has a blocked doorway with a fixed window to the right, both beneath flat stone arches. The right bay features a blocked doorway beneath a segmental arch.

On the first floor, there is a squat, central six-pane sash window in an eared architrave, set on a continuous bracketed panelled sill. The outer bays have five course brick bands at the first floor level. The main house has overhanging eaves supported by brackets, a hipped roof on the central bay, and wide gable coping on the outer bays. The outhouse has a single pitch roof with coping. There is evidence of a raised and blind coped parapet on the right bay. No internal features of interest have been noted.
