4, Union Place

No. 4 Union Place is a terrace house built around 1800, part of a planned group of six houses on the Castle Estate designed by Joseph Medworth, who lived from approximately 1754 to 1827. The house is constructed of local brown brick and features a modern interlocking tile roof along with a pantile roof. It stands three storeys tall with a basement and has four bays, including a side passage on the right with a boarded door and a painted panel instead of a fanlight, all set within a round-headed brick arch.

The main entrance showcases a wooden doorcase with fluted pilasters and a broken pediment, a plain round-headed fanlight, and a six-panelled door. The building has a shallow parapet with stone coping. On the second floor, there are two recessed hung sash windows with nine panes, set in cambered, gauged red brick arches with stone cills, along with two painted blind windows. The first floor features three twelve-paned hung sash windows and two on the ground floor, all in similar openings, with one painted blind window at each storey above the passageway. A painted stone cill band runs along the first floor.

Inside, the house retains a plain, original staircase, two reed-panelled chimney pieces, and panelled doors.
