The judgement call

Account-gated at launch

Adaptive reuse: A successful example of transforming a controversial temporary structure into a highly successful permanent venue. - Innovative construction: The arena's roof was erected using an innovative structural methodology, avoiding the need for tower cranes. - Acoustic design: Significant effort was put into the acoustic design to ensure a high-quality experience for concerts and events.

Key engineering challenges

Converting a temporary exhibition structure (Millennium Dome) into a permanent, world-class entertainment arena. - Constructing the arena within the existing dome, requiring careful integration and structural solutions. - Designing and erecting the arena's roof system without the use of traditional tower cranes. - Achieving optimal acoustics for a multi-purpose entertainment venue within the existing fabric.
