Broadway Malyan's design for an 87-storey tower on the South Bank looks set to run into immediate planning trouble with Southwark Council, whose planning policy states that 'the borough is not considered an appropriate area for tall buildings.' The giant 420m tower has yet to be submitted for planning and when an application is made in the summer the new mayor is sure to scrutinise the proposal. So far, mayoral hopeful Ken Livingstone has said he wants a 'new generation of graceful tall buildings' but has described Canary Wharf as a 'ghastly slab,' while rival Steve Norris' policy spokesman said: 'We don't have a problem as long as it doesn't shadow buildings of historic importance such as St. Paul's'. Broadway Malyan's tower design is for a diagonally-braced structure with a fully glazed facade and would cost around £600 million to build. The developer is Sellar Property Group.
