20, Brunswick Terrace

No. 20 Brunswick Terrace is a house located at the end of the terrace, built between 1823 and 1827 by Morris Clarke and George Cox. The building features a rendered exterior and a slate roof. It has a narrow-frontage, double-depth plan with a dogleg rear staircase and a lower service wing. This house is slightly higher and set forward from No. 19, and its elevation aligns with No. 2 at the start of the terrace.

The structure has three storeys and one window. It includes a small flat-roofed dormer above a three-storey bow with 8:12:8-pane sash windows and a dentil cornice at the ground and first floors. On the second floor, there is a blind light to the left, while the ground floor features an arched doorway with voussoirs and a keystone, a plain fanlight, and a reeded transom above the panelled door. There are plat-bands above the ground and first floors, a thin moulded cornice, and a parapet that returns at the left-hand end. A deep brick stack with clay pots is located on the right party wall. The rear of the house has a large 20th-century dormer behind a parapet, and the rear wall contains 12-pane sash windows.

The interior has not been inspected. This house is the last in the formal terraces at the northern end of the Esplanade. It is possible that the terrace originally extended to the right, where two later houses, Nos. 21 and 22, now stand.
