The Surrey, Kent and Sussex Banking Company had been established at Southwark in 1836 and soon had branches in places like Croydon, Brighton, Maidstone and Woolwich. It was renamed the London and County Banking Co. in 1839. By 1875 it had over 150 branches and was the largest British bank. After a series of mergers with the London and Westminster Bank in 1907; and the National Provincial Bank in 1968 to form Natwest, now a part of RBS. Not constructed completely as illustrated (banking hall doorway and adjacent windown were swapped), it’s still in use today as a bank branch.

The materials used are red brick, the ornamental details being executed in Watcombe terra-cotta. The roof is covered with green Eureka slates. The architect is Mr. F.
