A flurry of major office lettings in the last three months boosted London’s office market to 6.4 million sq ft (594,000 m2) in 2009, according to new figures from Cushman & Wakefield. Some 41% of the year’s total take-up of office space took place in the last quarter as corporates moved to secure deals believing rents to have bottomed out. The take-up of 2.6 million sq ft is the highest quarterly figure since the collapse of Lehman Brothers in September 2008.
