1 Undershaft, Proposed skyscraper in City of London financial district, United Kingdom
1 Undershaft will be a new tower in London's Eastern Cluster, planned with 73 floors and nearly 290 meters in height. At the top sits a public viewing platform with 360-degree views, free to enter.
The site was once home to another office tower, which was demolished to make way for this new project. Approval for construction came in 2016, with later revisions adjusting the height and floor count slightly.
The tower includes an education space at the top levels where school groups can learn about the city's past. This area remains free to visit and brings London's past closer to students and travelers.
The core of the building is set to one side, creating office floors without internal columns and allowing open, flexible layouts. Beneath the main tower lies a public courtyard with shops and cafes, guiding pedestrians from Bishopsgate to Leadenhall Street.
The design uses weathering steel on the facade, giving the tower an industrial appearance. Horizontal white metal shades protect the glass walls and create contrast with green glass facades on nearby buildings.

Everywhere, in deserts, along coasts, and in city centers, new building projects change how cities grow and work. Some build tall towers that change the view, others create whole neighborhoods from scratch. Each project shows different ways of thinking about design, technology, and how people live together. In Saudi Arabia, The Line offers a city without cars that runs through the desert, Trojena gives mountain skiing, and Sindalah builds a new island in the Red Sea. In Dubai, buildings like One Za’abeel, where two towers connect with a hanging bridge, or Dubai Creek Tower that switches the look along the water. In Paris, the Tour Triangle, a glass pyramid in the south, shows how the city considers height and space. These projects are of different sizes and purposes. There are large factories like Oxagon that work on the water, and places to live or work in Jeddah, Zhuhai, and elsewhere. Some are already being built, with the bases and structure going up, others are waiting for permission or funds. Each project aims to meet local needs, whether for more homes, attracting visitors, or trying new ways to build that care for the environment. Together, they show how architects and city planners think about the links between buildings, roads, and daily life around the world.
