1 Undershaft

1 Undershaft will be the tallest building in the City of London; creating a place for all who work, visit or live in the capital. 1 Undershaft’s confident and bold exterior is designed to make the building efficient, providing premium flexible office space. Central to the proposal is the new public square at street level with an open landscape leading down to a retail gallery. At the top of the building will be a free public viewing gallery, education centre and restaurant.
