The Uruguayan architect has chopped nine storeys from the top of the unusually curved tower following demands from the City of London's planners to reduce the height of the scheme.
Last month the authority told the developer Land Securities that the original proposals for a 45-storey building could block important sightlines towards St Paul's Cathedral and that the 192m-tall tower would have to shrink ( Viñoly's 'Walkie Talkie' skyscraper set to shrink).
Now Viñoly has submitted a revised application for a 'significantly reduced' scheme, which is expected to go before the planning committee in September.
Describing the changes to the tower, which will cut down the size of the development from around 85,000m 2to 55,000m 2, a spokesman for Land Securities said: 'It is essentially the same building - just shorter.
'We were not aware of the problem with the views until about a month or two ago, but we have responded to the concerns.'
If planning permission is granted later this year, construction work could start next autumn.
The skyscraper, which is close to the Tower of London, will house offices, shops a café and a new public Sky Garden ( pictured below).
