London is said to be the most sought-after in the world for office space, a recent study has shown.

Figures from the Urban Clear Institute and PricewaterhouseCoopers (PwC) show that total office sales in the Capital climbed to £6 million in the second half of 2009 – almost twice the value of transactions done in the six months prior.

The weakness of the pound against foreign currencies and the slide in prices that made the Capital attractive to private investors and sovereign wealth funds, are said to be the factors that have influenced this surge of interest in commercial property in London.

Prices in the Capital had fallen by half over the previous two years, by July last year – the most noticeable decrease in any European city.

The national pension fund, operated by South Korea, which completed a deal for £1 billion for the HSBC’s London headquarters in Canary Wharf, best illustrates the mark left by the state-backed investment vehicles.
