Description
Cosham House is a villa built around 1840, featuring a stucco exterior and a low pitch hipped roof covered with Welsh slate. The building has two storeys and five bays arranged in a 1:3:1 pattern, with the outer bays slightly projecting. A verandah spans the ground floor, supported by thin cast-iron columns with caps. The frieze is timber panelled and bows around the central three bays, topped with a tented roof.
At the centre, there is a large two-storey bow window with three glazed two-leaf French casements, flanked by similar French casements. On the first floor, the central bow window contains three sash windows, with tripartite sashes on either side featuring a wide centre sash and narrow flanking sashes. The building has wide projecting bowed eaves, and the bow window is topped with a conical roof. Below the eaves, there is a slightly projecting band.
To the left, there is an entrance featuring a two-leaf door with four moulded panels, where the upper panels are glazed. This entrance has a fanlight and a projecting porch with a round arch opening, complete with a moulded architrave and an ornate bargeboarded pitched roof. Adjacent to the entrance is a tripartite canted bay window with a central sash and two narrow side sashes, divided by paired pilasters, and topped with a frieze and cornice. On the right side of the building, there are two narrow casements. The first floor features a canted tripartite oriel with a lead pitched roof and blinded flanking windows set within a stone moulded architrave. The interior has not been inspected.
