Fifty-five charities and social enterprises using an office managed by the charity Can must relocate because the owner wants to refurbish the building.
After seven years, Can's lease on three floors of the building near London Bridge expires in March 2011; the landlord wants to gut the building, according to Can.
Can, a social enterprise that houses 129 not-for-profit enterprises in three locations, has set up a consultation process to help the charities find alternative workspaces. It is hoping to find another permanent office location, but is also offering organisations a space in its other offices in the capital, in Southwark and Shoreditch.
Andrew Croft, chief executive of Can, said 60 per cent of the organisations had decided what to do. "It's an opportunity for them to assess what is right for them," said Croft. "They can decide whether they would be better off with a virtual office or even their own lease."
