Developers aim to create a new business and cultural district, served by an extension to the Northern line, and glass tower blocks are under construction all around. Projects include the huge Nine Elms development between Vauxhall and Battersea, which will host the relocated Â£620 million American embassy. But there are complaints that landlords want multinational tenants to move in at the expense of smaller independents.
