Part of the premises of the bank has been occupied since the removal of Messrs Coutts--in 1904, to No. 440 Strand--by the London County Council. The number is 59, and the upper part is much the same as it was in 1768, when it was erected by the brothers Adam. The house then contained "some good marble chimney-pieces of the Cipriani and Bacon school. The dining-room is hung with Chinese subjects on paper, sent to Coutts by Lord Macartney, while on his embassy to China in 1792-95. In another room is a collection of portraits of the early friends of the wealthy banker, including the portrait of Dr Armstrong, the poet, by Sir Joshua Reynolds. The strong rooms, or vaults of the house--'which alone cost £10,000'--will repay an endeavour to obtain a sight of them. Here, in a succession of cloister-like avenues, are stored in boxes of all shapes, sizes, and colours, patents, title-deeds, plate, etc., of many of the nobility and gentry of Great Britain."[50] The Adams mantel-pieces and some of their doors were transferred to No. 440 Strand; and here the board-room--an apartment of drawing-room appearance which is in strange contrast to the busy thoroughfare below--is hung with the Chinese wall-paper which, despite its hundred and more years of age, looks perfectly new. During the building of the Adelphi, Coutts, in order to prevent the interruption of the view from the back part of the premises, made a stipulation with the Adams that Robert Street should be so planned as to form a kind of framework for the fine view of the hills beyond the Thames. The land beyond John and William streets was then occupied by the strong-rooms, "connected underground with the office, and built only to the level of the Strand. When it became necessary to enlarge" the premises, Coutts "procured a special Act of Parliament for throwing an arch over William Street. It was recognised as a good omen that, on the day of opening these improvements, Nelson sent to Mr Coutts for security the diamond aigrette which had been presented to him by the Sultan."[51] In James Street--now covered, with William Street, in the general name of Durham House Street, stretching from the Strand to John Street--was the Adelphi Chapel, built by a congregation of Particular Baptists about 1777, and subsequently sold by them to the Calvinistic Baptists. Later on, an Independent congregation occupied the building until it became absorbed in the banking-house, and, until the removal of Messrs Coutts, it was called "the chapel."
