The City leasing market has seen one of the highest monthly take ups on record in May, with a total of 793,400 sq ft being let, according to Jones Lang LaSalle. This figure is up by 117% month-on-month and 135% on May last year, bringing the year to date take-up to 2.2m sq ft, a 46% increase on the equivalent period in 2012. Jones Lang LaSalle recorded five lettings over 50,000 sq ft during May, of which three were pre-lets exceeding 100,000 sq ft. These include Amazon at Sixty London, EC1 (213,000 sq ft), Bird & Bird at 12-14 New Fetter Lane, EC4 (136,200 sq ft), and Amlin at The Leadenhall Building, EC3 (111,800 sq ft). Dan Burn, Director of Office Agency at Jones Lang LaSalle said: "Despite a number of large deals completing this month, there remains a very healthy level of activity, with almost 1.4m sq ft currently under offer and active demand currently registered at 6.6m sq ft. "The combination of strong levels of current activity and the low level of speculative development is forcing occupiers to bring their future requirements to the boardroom agenda. This is especially prevalent for those occupiers with lease events in 2015- 2018, as concern rises over the long term availability of suitable product." Notable deals in the pipeline include CMS Cameron McKenna at Canon Place, EC4 (140,200 sq ft), Field Fisher Waterhouse at Riverbank House, EC4 (80,000 sq ft) and key new potential City requirements launched since April include M&G (250 -300,000 sq ft), TFL (150,000 - 200,000 sq ft), News International (400,000 sq ft ) and Rabobank (100,000 sq ft). Burn added: "We anticipate upward pressure on prime rents which currently stand at £57.00 per sq ft, following a rise of 3.6% in 2012. A combination of eroding levels of current supply, strong demand for product being delivered in 2014, of which nearly 60% is now let, and pre-let activity continuing, will strengthen landlords stances and put further pressure on prime rents in the City."
