Herbert Smith, Freshfields Bruckhaus Deringer, Clifford Chance (CC) and Nabarro have all taken roles on Hammerson's £518m sale of its London commercial property portfolio to Canadian investor Brookfield.

The FTSE 100 property company, which announced its intention to sell its London office buildings in February to focus exclusively on retail assets, has handed roles to Herbert Smith, CC and Nabarro – all of which are on its property panel – on the individual sales.

Herbert Smith advised on the sale of 99 Bishopsgate – which houses the London office of US firm Latham & Watkins – Principal Place and two smaller properties, with the firm's team led by real estate partner Julian Pollock.

CC advised on the sale of 125 Old Broad Street – the London base of France's Gide Loyrette Nouel and US firm King & Spalding – with a team led by real estate partner Jonathan Solomon.

Nabarro, meanwhile, acted on the sale of EC3′s Leadenhall Court, with the firm's team headed up by real estate partner Simon Staite.

Brookfield, which also owns a number of properties in downtown Manhattan as well as a 22% stake in Canary Wharf, instructed Freshfields on the deal, which fielded a team led by real estate partner John Fordham.

Hammerson, whose portfolio now consists largely of retail properties including London's Brent Cross, expects to receive a payment of £329m for 99 Bishopsgate by the end of September. The sale of the other buildings, 125 Old Broad Street and Leadenhall Court, will be completed by next June for £189m.

Hammerson said it would use the proceeds from the sell-off to invest in retail developments and acquisitions, as well as a number of extension and refurbishment projects in its UK retail parks, adding that it had identified projects worth £320m.
