The Story

"Irvine Sellar, The Shard’s developer and joint owner, had an ambitious vision to create an architecturally striking vertical city incorporating retail, offices, hotel, apartments, restaurants and a public viewing gallery. His idea was to build a diverse vibrant community, and provide multiple areas within which the public could experience the building and its magnificent views. And all of this astride one of London’s major transport hubs.

The finished building remained true to the original vision of a “Vertical City” with multiple and different occupiers, many of which will operate 24 hours a day, including hotel, education, medical, tourist attraction, residential, retail, restaurant, and offices. The Shard’s proximity to London Bridge Station, which itself is being transformed into a 21st-century transport hub used by 75 million people a year, means travelling to it is a smooth experience for occupiers and visitors alike."
