Nouvelle AOM has just been chosen to transform Paris’ historic Tour Montparnasse into beacon of sustainability for the City of Light. The winning design envisions a contemporary green makeover for the 40-year-old skyscraper – including a new transparent shell cladding and forests in the sky that will improve air quality in and around the tower. The 689-foot Tour Montparnasse was completed in 1973, and it was France’s tallest skyscraper until 2011.
