When you think of innovative 21st-century architecture, Paris isn’t the first city that springs to mind. But these ambitious Foster + Partners–designed twin skyscrapers will challenge that perception once completed. They are on track to become the tallest buildings in the EU, topping out at 1,050 feet, and will provide the business district of the city, east of La Défense, with a riverfront park lined with shops and restaurants. The towers are also energy efficient, with high-tech insulation and solar shading.
Launch Date: 2017
