Portico of Corinthian columns in front of the main house, with frieze and ornamental carving. Now part of the side porticoes at the National Gallery. The portico was a porte-cochiere, so carriages could drive through to the door.

Published in Pyne's Royal Residences, 1819, vol. 3, part 2 'Carlton House', plate facing page 12. Prepared for one of the plates in William Henry Pyne's 'History of the Royal Residences' (1816-1819). Engraved by Sutherland, the print published 1.10.1816. Pyne's 'History of the Royal Residences' was a three-volume publication which encompassed a number of royal residences, including Windsor Castle (vol. 1), Buckingham House (vol. 2),  and Carlton House (vol. 3) presenting 100 hand-coloured engravings of exteriors and interiors accompanied by descriptive texts. The 100 watercolours which were engraved for the publication survive in the Royal Library; these watercolours are exactly the size of the image on the printed plates, and may perhaps have been intended as colour guides for the artists responsible for hand-painting the monochrome prints.
