Offices in London are in dangerously short supply as the economy returns and the financial sector starts to seek more space.
Leasing activity last year hit its highest level since 2007 according to research by Cushman&Wakefield, with 12.4m sq ft of new lettings and leasing volumes in the City at a 15-year high.
But a lack of space, in part caused by the policy allowing offices to be converted to residential, has led to pre-lets hitting their highest level for a decade. According to Cushman seven companies committed to pre-lets of over 100,000 in 2014.
Analysts argue that rents could rise sharply in 2015 as a result.
