The Library-Drawing Room at Bromley-Hill exemplifies perfectly Humphrey Repton's idea of a 'living room', with its combination of the functions of library, drawing room and repository of the treasures of a noted collector. Charles Long, later Lord Farnborough, was involved in politics and was a friend of Pitt and Addington, but the activities suggested in this charming room are those of a notable member of the artistic establishment. He was an adviser to both George III and George IV, and made many purchases on their behalf; he was a trustee of the National Gallery and of the British Museum. He was married to Amelia, daughter of Sir Abraham Hume, who was an artist of some repute, and was himself a collector of Oriental ceramics. Other aspects of this scheme invoke Repton, notably the use of great overmantel mirrors to reflect and enlarge the space. In his Observations (1816) Repton wrote 'The position of looking-glasses, with respect to the light and cheerfulness of rooms, was not well-understood in England during the last century, although on the Continent the effect of large mirrors had long been studied in certain palaces: great advantage was in some cases taken by placing them obliquely, and others by placing them opposite: thus new scenes and unexpected effects were often introduced...'. Further on in the same passage on the subject of the convenient arrangement of interiors Repton enlarges on the conservatory 'Of all the improvements in modern luxury, whether belonging to the Architect's or the Landscape Gardner's department, none is more delightful than the connection of the living-rooms with a green-house or conservatory; although they should always be separated by a small lobby, to prevent the damp and smell of earth'.
