NOTES: This was one the six office towers constructed between 1957 and 1976 which, together with the Museum of London, formed the western flank of the London Wall development. It was extensively refurbished by Sheppard Robson International in 2000 and renamed CityPoint. The designers in charge of the special, i.e. prestigious, areas of the original interiors were from the Design Research Unit.
