A bit more has filtered through today about the supertalls planned in La Défense. French architect Manuelle Gautrand revealed on her website that she's working on a skyscraper in the 300s meters (1,000-1,300ft). The developer is Unibail. She said renderings would be made public in the end of September (little less than 3 months from now).
This is supposed to be one of several supertalls to be built in La Défense within the next 9 years, but it is not known whether the skyscraper that Gautrand is working on would be the tallest or the second-tallest. Bernard Bled, the director of La Défense Authority, has repeatedly (and again recently) said that the tallest tower would be above the 400m (1,310ft) mark.
