Office Adjoining St John's Ambulance Headquarters

The building is an office that adjoins the St John's Ambulance Headquarters. It was originally three mews buildings, dating from the early 19th century, with 20th-century additions. The materials used include painted limestone rubble and render, and each section has a hipped double Roman tile roof.

The exterior features two storeys and a two-window range. The block on the left has a 20th-century wooden external shutter over a six/nine-pane sash window at eaves level, which likely served as a former loading bay. The ground floor has a fascia above a 20th-century half-glazed timber infill. The central block has no windows on the first floor, with a higher fascia above a six-pane overlight leading to a 20th-century six-panel door on the left and a six/nine-pane sash window on the right. The right-hand block has a 20th-century full-height timber infill on the left, with paired six-pane windows on each floor, and to the right, there are traces of a blocked door with a three-pane overlight remaining. The interior has not been inspected.
