4, Downing Street

Number 4 Downing Street is an 18th-century building that stands three stories tall. It is constructed of brick and features a chamfered plinth. There are string courses at the first and second floor levels, and a moulded wooden cornice supported by pairs of cut brackets. The roof is hipped and covered with slate.

The upper floors have five tall windows, while the ground floor has four similar windows and a central six-panel door. This door is set beneath a later Greek Doric porch made of wood, which includes two wall pilasters, fluted columns, an entablature with a modillioned cornice, and a blocking cornice. The entrance is accessed by three moulded stone steps that curve out to the bottom step, which has curved ends.

On either side of the main block are two-storey wings that are set back from the main facade. Each wing has one window on the first floor. The left wing features a half-glazed door with a six-pane rectangular fanlight on the ground floor. The right wing has a later wooden porch extension, two windows, and a central glazed door framed with pilasters and an entablature, although this is now boxed in with wooden boarding.

Notable decorative features include good cast lead rainwater heads at the return angles of the central block, adorned with angel head ornaments. The building was illustrated in Country Life on July 10, 1942, in plates 6 and 7.

Number 4 Downing Street, along with Numbers 2 and 3 and the wall to Number 4, forms a group with the listed buildings on the south side of Lower Church Lane and should be considered in relation to them.
