40, Northumberland Place

40 Northumberland Place is a house with a shop, built around the 1820s. It features painted stucco with freestone coping on the parapet and window sills, and has a half-hipped slate roof with a large chimney stack on the left side. The building has a double-depth plan and includes a 2-storey rear right wing.

The exterior consists of three storeys with an attic and a three-window range. It has moulded architraves and a circular attic window above the central 6/6-pane sash windows on the upper floors. These windows are flanked by curved bays that contain tripartite 6/6-pane sash windows with cast-iron balconettes. The late 19th-century shop front features a moulded cornice and ornate cast-iron cresting on the fascia. To the far left, there is a set-back 20th-century door, and another 20th-century glazed door is located on the inside left, both with 3-pane overlights. The central shop window is bowed and small-paned, flanked by similar flat windows. The right side of the building is plain, while the right side of the rear wing has a 6/6-pane sash window on the first floor and a 20th-century window on the ground floor. The interior has not been inspected. The facade is distinguished by its bowed oriel window and features an exceptionally fine late 19th-century shop front.
