Masterminded by funder Schroders and development manager Stanhope, the project consists of a 63-storey main tower with an adjacent 22-storey building.

Among the professional client team, contractor Multiplex has drawn up the outline construction environmental management plan for the new tower in the main Square Mile cluster.

The redevelopment of 55 Bishopsgate will create 130,000 sq m of new commercial floorspace and publicly accessible spaces within a building of striking design.

Innovative megaframe design for 55 Bishopsgate project

Details of the megaframe design which provides a higher lateral stiffness than achieved for conventional core and outrigger structures at its 285m height.

Architect AFK  with structural engineer Robert Bird Group have devised an innovative ‘fibonacci leaf’ design for the tower’s perimeter steel megaframe.

This design resists lateral movement in the building reducing both steel tonnages and wall thicknesses of the central concrete core. It also allows for column-free floor plates.

The building will also feature a rooftop triple-height conservatory for events and a public viewing platform at its pinnacle
