Post Office

The Post Office, formerly known as the Telephone Building at the rear of No. 4 London Bridge Street, is a former ward block of St Thomas's Hospital, built between 1842 and 1844 by architects Samuel Robinson and James Field. It is constructed of Portland stone with a channelled rustication on the ground floor and features a slate roof.

The building is designed in a late Georgian style and has three storeys. The elevation facing Borough High Street has one bay, with a blind window set in a revealed square-headed architrave at the center of the rusticated ground floor, which is topped by a cornice. The two upper floors contain 18-pane sash windows set in moulded architraves, with a bracketed cornice on the first floor and an eared architrave on the second floor. These floors are enhanced by a giant order of Doric pilasters and a dentilled entablature, culminating in a raised parapet at the center.

The side elevations, which are similar in design (with the southern side mostly obscured), consist of three storeys and a basement, displaying a pattern of one, three, one, three, one bays. The projecting outer and central bays are articulated by Doric pilasters. The ground-floor windows are set in revealed architraves, while the upper windows feature eared architraves and a sill band on the second floor. The projecting central bay includes tripartite windows with Doric piers and a parapet above.

The interior has not been inspected. The building occupies part of the site of Court A of the old St Thomas's Hospital and is located directly north of the former Church of St Thomas.
