Developer Grosvenor has beefed up the number of affordable homes on its £500m build-to-rent housing scheme in Bermondsey, south east London, in an attempt to get the project past local planners.

In February Southwark council threw out the firm’s initial proposals to build 1,342 homes, of which only 27% would have been affordable, on the site of the old Peek Freans biscuit factory.
