ExCeL London Phase II Extension

London, England · 2010 · Not readily available (original building £550 million, Phase II part of significant investment)

The judgement call

Account-gated at launch

Seamless integration: The extension respects the existing architecture while adding a distinctive new entrance. - Natural lighting and ventilation: ETFE roof panels were used to prevent 'exhibition fatigue' by providing natural light and air. - Enhanced connectivity: The extension improved DLR links and pedestrian traffic flow.

Key engineering challenges

Extending an existing large structure by 32,500 sq m while maintaining operations. - Creating an identifiable eastern entry with a vibrant yellow spiral that also serves as a landmark for navigation. - Integrating the new extension with the established scale and materials of ExCeL Phase I. - Incorporating large ETFE roof panels to flood the central boulevard with daylight and provide natural ventilation.
