House, including garden walls with terracotta dressings and pinecone finials

Nos. 18 and 19 Fosterville Crescent are a semi-detached pair of houses built of yellow brick, featuring caramel coloured terracotta quoins and window and door dressings. They have a red tile roof with yellow brick chimney stacks. Each house has two storeys and attics, with three windows on the front. At either end of the pair, there are three-storey gabled wings, each with a two-storey canted bay and a single window above, which has a heavy keyed surround in the gable. The bays are finished in terracotta with rusticated surrounds, stiff-leaf capitals, and a stiff-leaf band on the upper apron. The windows are plain sash types with keyed heads, and the roofs have eaves supported by brackets. The gables feature fretted bargeboards.

The central range has paired windows on the ground floor and recessed balconies above, which are adorned with wrought iron railings, a door, and a sash window. All windows are 2 over 1 pane sashes, and the doors are part glazed. The return elevations consist of three bays, including a large gabled porch with a wood-framed oriel on the left and additional single sashes, with the top floor window set in a gablet. The roof is detailed with ridge tiles, spike finials on the gables, and tall chimney stacks—one located on the ridge between the houses, one on each return wall (the left one is truncated at eaves level), and one at the rear of each wing. There are also roof-lights on the front.

Each house is enclosed by a rubble street wall topped with rounded terracotta capping, square piers with pinecone finials (one finial is missing on the left), and decorative cast iron gates. The house has retained the chimney on the right return, while the rear elevation has not been inspected. The interior was not seen during the resurvey.
