37A, West Street

37A West Street is an early 19th-century house located in Harwich. It is constructed of red brick and features a Welsh slate roof with a parapeted gable at the northwest end. The building stands three storeys tall and has a stack that rises through the roof slope near the northwest gable, along with corbelled eaves.

On the exterior, the second floor has two recessed double-hung sash windows with margin glazing, which are set under slightly arched rubbed brick heads. The first floor features two similar but deeper double-hung sash windows. The ground floor has one near-central double-hung sash window, a black tarred plinth, and an entrance door that has a reeded surround and a flat hood. This entrance door is accompanied by a rectangular margin glazed fanlight and has six raised-and-fielded panels. At the rear, there is a single-storey lean-to extension.

Inside, the property has been much altered, but a short length of the early 19th-century staircase remains, showcasing a column newel and stick balusters.
