The Concept

One Leadenhall is a 176-meter-high tower designed by the architectural firm Make. This 35-story building offers 40,000 sqm of office space, a free public terrace, and ground-floor shops in an important corner of the City of London, next to the historic Leadenhall Market.
Its sophisticated aesthetic blends seamlessly with the cityscape, with panoramic views on every floor ensuring that tenants always feel connected to the urban landscape around them.

The public terrace on the fourth floor will offer a significant new view of the City of London.
The project targets BREEAM Excellent and WELL Platinum.
