A 3D image created by architects has shown what London's skyline will look like in 2010.
The software created by GMJ Designs shows the impact of planned skyscrapers, such as the 310m Shard, on the City of London.
The CityModel covers 36sqkm including Southwark, the City and the West End.
Unesco, the United Nation's cultural agency, has warned sights like the Tower of London are being blighted by the more and more high rise buildings.
It added it is on the verge of being placed on the United Nation's Heritage in Danger List.
Managing director of GMJ Designs, Didier Madoc-Jones, said: "It's a highly sensitive issue building new tall buildings in London because you have lots of protected historic buildings.
"All the fantastic new buildings that are going up in the City will have a massive impact on the skyline so at the planning stages it is incredibly important to visualise how these buildings are going to appear.
"Using our CityModel we are able to plot these buildings so that the planners and developers can rapidly understand what the proposals are."
The computer image of the 2010 London skyline shows the Shard, the 288m high Bishopsgate Tower, 224m tall Leadenhall and 242m Heron Tower.
