Selected areas of the existing floor plates were extended out into the atrium to form meeting spaces and a link bridge spanning the top of the atrium was introduced for further connectivity.

The key architectural feature of the triple-height entry space was realised with detailed performance-based analysis involving multi-scenario fire, smoke and people movement modelling. All three buildings feature multi-storey interconnecting stairs over four levels that allow occupants to move seamlessly around the floor space.

Consideration of the fire and life safety challenges throughout the construction period allowed for a progressive occupation of the building such that business operations continued throughout the refurbishment process.
