The defining feature of The Leadenhall Building is its distinctive tapering shape, angled at 10 degrees. Whilst most high-rise buildings are built around a central concrete core to provide lateral stability, The Leadenhall Building has a steel megaframe which gives the building its strength and also means office floors have very few internal columns, allowing a great deal of flexibility in how the space can be used.
The north core is animated by its array of glass panoramic lifts. They are the fastest in Europe, taking just 30 seconds to reach the 45th floor. The activity and movement of the 6,000 people who will work in The Leadenhall Building will be seen behind the encasing glass contributing to the experience of The Leadenhall Building from outside.
