The firm's backing for the £750m Spitalfields choice on the edge of the City follows a weekend partnership meeting.
The decision marks the firm's rejection of a wholesale move to Canary Wharf, where A&O has taken space for a satellite office. Other sites considered have include Lehman Brother's Northgate Scheme in Hackney, 201 Bishops Gate, Paternoster Square and London Bridge City. The 750,000 sq ft Spitalfields scheme will be developed by the Spitalfields Development Group, which is now a subsidiary of Hammerson. Norton Rose, Nabarro Nathanson and Clifford Chance are advising the developer. Linklaters & Alliance is acting for A&O. A deal on the Spitalfields site would draw a line under a series of planning headaches for the scheme after Liffe, the London international financial and futures and options exchange, pulled out of plans to make its own headquarters there.
