1a, 1b, 1c, King Street, St James's SW1

The terrace houses at 1A, 1B, and 1C King Street, St James's, were built in 1846 by the architectural firm of Elger and Kelk. They are stucco buildings with slate roofs and represent an Italianate terrace design. The four-storey-and-basement elevation is finished with a Vitruvian scroll frieze, a dentil cornice, and a coped parapet. Each house has two bays, with number 1C slightly projecting. Shallow porches with attached Doric columns are on the left side. The ground floor is channelled and features a continuous vermiculated frieze band incorporating tripled keystones above the entrance doors and windows. The first and second floors have sash windows without glazing bars, set within architraves that have segmental pediments on the first floor and consoled cornices on the second. The third-floor windows are plain and sit on a sill band. The inner bays of numbers 1A and 1B feature side lights. A first-floor balcony has ironwork replaced in the mid-20th century, and area railings have also been renewed during the mid-20th century. Number 1C displays a Minton ware commemorative plaque, installed by the Society of Arts in 1875. The plaque is inscribed "Napoleon III (1808-1873) lived here 1848," and is one of the earliest surviving plaques erected by the Society of Arts. The terrace now forms part of number 18 St. James's Square.
