Italian architect Renzo Piano will be appearing at the London Bridge Tower Public Inquiry opening on Tuesday 15 April.
The proposed building next to London Bridge Station is over a thousand feet high and more than 200 feet higher than Canary Wharf Tower. It would be Europe's tallest building.
Professor Piano says: "I see my tower as a small vertical town with about 10,000 people working there."
Irvine Sellar, who has commissioned the design, claims that the skyscraper will be a gateway to work opportunities with an onsite drop-in and training centre.
The tower proposal is supported by the Mayor of London and both the Corporation of London and Southwark Council.
