This is the latest image of Sheppard Robson’s proposed redevelopment of York House next to Waterloo station in London

The project, for Delancey, will take the form of an 18-storey drum enclosing 32,000m2 of office space and a roof-top terrace. The fully glazed facade is divided into two skins with wedge-shaped diagonal fins between them creating a crystallised effect. The scheme received planning permission in May and should be completed in 2010.
