The London commercial real estate market has become a global destination of choice for foreign investors, with £19.9 billion invested in 2013 and non-UK buyers accounting for 72 percent of transactions, according to Cushman & Wakefield. The investment in the usually quiet first quarter of 2014 alone topped £4.3 billion.

Some 35 nations have been identified by Deloitte’s real estate team as entering the market, with strong interest from Canada and Norway. But interest from China, South Korea and Southeast Asia is particularly bullish with national savings institutions, such as pension funds, allowed to invest outside their own markets for the first time in recent years.
