LaSalle Investment Management is under offer to buy the City of London headquarters of ING for £197.5m from Deutsche Fonds Holding on behalf of the California State Teachers Retirement Fund.
The fund manager has secured exclusivity on 60 London Wall, EC2, with the deal due to exchange this week.
The firm is expected to pursue a substantial refurbishment and two-floor extension of the 260,000 sq ft building, which will be vacated by ING in favour of 8-10 Moorgate, EC2, later this year.
