  • The tower has a central core with visible steel cross bracing to the exterior.
  • The tower's lifts are the world's first to be both double-decker and equipped with destination control.
  • 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 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 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.
