40 Leadenhall Street

40 Leadenhall Street is a 34-story glass and steel structure that rises 155 meters above London's skyline with a geometric profile created by vertical slices. The building delivers 900,000 square feet of office space while incorporating a preserved 1865 structure at its base.

The site was developed starting in 2011 around a preserved 1865 building at an adjacent address, creating a connection between modern construction and historic London. This approach preserved an earlier structure as part of the new tower's foundation.

The stepped design respects local architectural guidelines and maintains clear views toward St Paul's Cathedral from the ceremonial route via Fleet Street.

The site provides 1,067 bicycle spaces and facilities for visitors with mobility devices, including dedicated charging points. Showers and changing facilities are available inside for anyone needing to freshen up after arrival.

The structure emits 30 percent less carbon than current regulations permit, making it one of the most environmentally conscious towers in the city. The vertical composition with cascading levels allows daylight to reach most office spaces.
