Wellington Hotel including rear wings

The Wellington Hotel, which includes rear wings, is a hotel with a stuccoed facade facing The Bulwark. It stands three storeys tall and features seven windows, topped by a slate roof. The building has a modillion cornice and blind windows above. The corners are chamfered, and there is a band above the ground floor. The windows are hornless sash types without glazing bars, set within moulded architraves. A late 19th-century porch supported by iron posts features a pedimented canopy and double fielded panelled doors with an architrave. There is a segmental arch leading to the yard entrance in the right (northwest) bay.

The gable end facing Glamorgan Street also rises three storeys and has two windows with a cement render finish. It features tall sash windows with small-pane glazing, one of which has horns on the first floor, while smaller sash windows are present on the second floor and small windows on the ground floor. A shallow wing projects at right angles from the southeast side of the gable end. To the northwest, there is a longer 19th-century wing with stone rubble walls and a stone slate roof, accented by brick dressings. This wing has two windows with three-centred heads on the first floor, and on the ground floor, there are three windows with cambered heads and a blocked doorway with a three-centred head. The northwest gable end has a circular attic lunette and a window with a cambered head on the first floor, along with a modern vehicular entry on the ground floor.

Inside, there is an early to mid-18th-century wooden staircase in the large entrance hall. This hall and the northwest ground floor room feature ceilings with small modillion cornices similar to those found in the stair-wall of No. 11 The Bulwark and in the vestibule of No. 4 Lion Street. The interior also contains some 18th-century fireplaces and panelled doors from the 18th century and later. The lower rear wing includes some 17th-century elements, such as chamfered beams.
