20 And 21, Hillingdon Road

Nos 20 and 21 on Hillingdon Road are an early to mid-19th century pair of houses, each standing three storeys tall with a basement and featuring two windows. They have narrow, set-back outer entrance extensions and are topped with hipped slate roofs. The buildings are constructed from stock brick and have gauged flat brick arches above the sash windows, which include glazing bars. The doors consist of three horizontal panels; the door of No 20 is set within a modern porch that has a sloped tiled hood, while No 21 features an early Victorian trellis porch with a fishscale slated roof. These properties, along with Nos 11 to 24 and No 25A, form a group.
