Although the design watchdog praised the firm's ‘simple, elegant and efficient’ approach to temporary seating, it still has issues over the external ‘wrap’ and public space around the stadium.
The design review report said: ‘There are concerns that aspects of the design remain unresolved at this stage in the planning process – for example the proposed temporary "pods" and public space around the stadium.
‘This raises serious questions about how and when these elements will be addressed, and by whom, since they are not the responsibility of the stadium design team.’
Paul Finch, chair of the London 2012 design review panel, said: ‘We think the idea is smart and appropriate and that the stadium will be a spectacular feature of the 2012 Games.
‘As for our reservations, we have every confidence that these can be addressed by the Olympic Delivery Authority and the London Organising Committee of the Olympic Games working together as a joint client, with their skilled and experienced architects and designers.’
