Key features

Extension with steel-framed structure

The existing sixth floor was replaced by a 3-storey steel-framed extension, providing two new levels of workspace.

Reconfiguring the cores

Re-coring with a braced steel frame, rather than the original reinforced concrete proposal, helped improve the construction programme.

Modified floorplates

Extensive internal demolition and new construction to modify the floorplates, creating generous floor-to-ceiling heights and making a feature of the retained structure.

New public thoroughfare

By extending the pre-existing Nun Court, new ground floor retail and leisure spaces are facilitated.
