The developer behind London's skyscraper the Shard of Glass loves building tall buildings so much, he is planning three more!

Developer Irvine Sellar has commissioned Beijing Bird's Nest architects Herzog and de Meuron to design towers rising 100, 200 and 250m high.

They are planned for a site near the Shard at London Bridge Station and will stand just south of City Hall.

A planning application is expected within two months and construction should take seven years.

There are plenty of opponents and one estate agent has commented Sellar is "building his own competition" and is already having trouble selling pads in the Shard.
