This is the leaked image of the Richard Rogers Partnership design for the Riverside South site in Canary Wharf, which AJ can exclusively reveal. It is the first time renderings for the project have seen the light of day. Described by a source who is close to the project, as 'trying something new', it is understood that high-level discussions have taken place within the Canary Wharf Group that have resulted in a decision on the need for a change of style - in this case buildings that retain some of the 'boxyness'of the estate but have greater diversity of design. The current proposals for the two 40storey towers feature classic Rogers styling with a height to the crowns of the buildings of 200m. In addition, the southern tower will have a spire rising from its roof by as much as 40m. However, the project remains at early stages, having not officially been announced by the Canary Wharf Group. Work is still at preplanning stage, so there is a possibility that the renderings will be developed further. The engineering group Yolles is being consulted about the structural design of the towers in its Canada offices.
