The tower is supported by a 6,000 tonne concrete and steel raft which straddles a railway tunnel. The west side's foundations descend to ground level whilst to the east, the tower is supported by a 5-storey A-frame which performs the task of a flying buttress.
The building is 50% more energy efficient than a comparable building of similar dimensions.
The tower employed around 14,000 tonnes of steel in its construction.
The Broadgate tower has 877 steps.
The tower is clad in around 40,000 square metres of glass, roughly equal to the surface area of 154 tennis courts.
The tower has a central core with visible steel cross bracing to the exterior.
There is a level difference of approximately 3 metres between the northern end of the site and Worship Street, so that the columns of the northern facade begin at a height of +14.4m AOD whereas the remainder of the building is grounded at a level of +17.15m AOD.
The tower's lifts are the world's first to be both double-decker and equipped with destination control.
