Designed by Foster + Partners for London, the “Tulip Tower” – a 1000 feet tall tulip-shaped skyscraper which – in 2025 it was to become a major tourist attraction and a new icon of the city. The British government, however, following a lot of controversies, has decided to stop its construction due to its environmental impact and design.

The city council, justifying its decision, stated that the measures that would have been taken to minimize carbon emissions during its own construction would not have been sufficient to offset the environmental impact of the building's function itself. The UK housing secretary, Michael Gove, said about this that the economic, tourism and educational benefits of the Tulip, were outweighed by the harm it would cause to the significance of designated heritage assets. The minister argued the new tower would have a negative impact on the value of the nearby Tower of London, because – when viewed from Tower Bridge – it would rise up into the sky directly behind the ancient monument.

Foster + Partners said: "We feel that London has missed a great opportunity to embrace a progressive vision for the future of the City".
