The Leadenhall Building

225 meters high cheesegrater as a new landmark in the skyline of London

Innovative, unique, spectacular – these describe the features of the Leadenhall Building. Its 10 degree inwardly inclined façade not only ensures an unmistakeable architecture, it is also the reason for its descriptive nickname "the cheese grater", given to it by the population before completion.
