The long leasehold interest for the Moorhouse office space scheme has been bought by German fund manager Deka.
The purchase cements a current trend of German investment in London office space.
The Moorhouse building at 120 London Wall is made up of 326,500 square feet of office space spread over 16 floors.
Deka bought the building, which is currently fully let, from Hammerson and Pearl Assurance for £229.8m.
The seven tenants of Moorhouse include Bayersiche Hypo-Und Vereinsbank, Pictet Asset Management and New Look.
The total gross passing rent for the office space is £16.3m a year, around £50 per square foot.
John Heaver, director of Savills, said: ‘Moorhouse is an extremely high quality asset with striking appearance and prominence in the core of the City of London and multi-let to a variety of prestigious tenants. Deka feel strongly that this landmark asset sits well within their portfolio.’
