Advertising and media firms are leaving London's West End in favour of the South Bank area, according to a report this week.
Dorrington’s Crane Building, in Bankside, is the focus of interest of both the UK arm of Cheil Worldwide and GroupM, Estates Gazette reported.
It said Cheil was believed to have placed an offer on the 48,200 sq feet building's ground to third floors, while Group M had taken the fifth floor, citing the moves as evidence of a trend for advertising and media firms moving south of the river.
Estates Gazette added that Rethink had taken the building’s sixth floor.
"We've already surpassed one degree of global warming," said Kristen Buida, manager of the London Climate Change Partnership.
