15, St James's Square SW1

No 15 St James's Square, known as Lichfield House, is a terraced town house built between 1764 and 1766 by James Stuart for Thomas Anson, with alterations made by Samuel Wyatt from 1791 to 1794. The building is faced with Portland stone and has a slate roof. It is a notable example of the Greek Revival style, featuring exquisite proportions. The house has three storeys and a basement, with a width of three windows.

The ground floor is smoothly rusticated, with openings set in an arcade. The entrance, located to the right, is approached by steps and features a panelled door flanked by recessed Tuscan columns, an entablature above the door, and a radial glazed fanlight. The glazing bar sash windows, which have rounded heads, are set in simply moulded surrounds. The piano nobile has elongated glazing bar sashes in simple architraves with pediments above, while the second floor features eared architraves.

These upper floors are distinguished by a single giant order of pedestalled fluted Ionic columns, inspired by Stuart's study of the Erechtheum, which support an entablature with a pediment above. A stone balcony across the first floor has a copper geometric pattern balustrade, an alteration made by Samuel Wyatt. There is a wave moulded sill band at the second floor.

At the rear, Wyatt added two-storey flattened bows and a three-storey rear wing with a rusticated brick ground floor, stone dressings, and a tripartite Venetian window arrangement on the first floor, which is a combination of Stuart's design and Wyatt's alterations. The interior was significantly remodeled by Wyatt between 1791 and 1794. Although Stuart's main staircase has been removed, the upper gallery and a fine glazed dome with eagle pendentives and "Wedgwood" medallions remain. The first floor features excellent decoration from both Stuart and Wyatt, with plasterwork by Joseph Rose and painting by Biagio Rebecca.
