In the report, the design watchdog says it is ‘not confident’ in the way the proposed park will serve the public and claims the office should reconsider the building’s roof.
The document reads: ‘We acknowledge the strength of the architectural concept, but remain unconvinced that the current proposal will enable the park to serve its function as a public amenity.
‘The image of a tree canopy rising out of the building is a compelling one. However, we are not confident that the proposed shell structure will allow this to be achieved in a meaningful way.’
It adds: ‘We urge the design team to re-evaluate how the roof can more effectively express or reveal the uses and activities contained within the building, including the park, as well as respond more subtly to the different environmental conditions at either end of the building.’
