Although the 165-metre-high Tour EDF is not the tallest skyscraper in Paris, it is unique because of its innovative design in elliptical ground shape, which is shorter at its base than at the top. The most striking characteristic of the building is the extrusion of a conic section of the tower on its northern edge.
The resulting conic hole extends from the ground floor to the 26th floor and serves as the main entrance to the tower – an entrance built under a wide, circular canopy, 24 metres in diameter. The maximal length of the tower is 70 metres and the maximal width, 32 metres. The cladding of the building alternates horizontal stripes of plain steel and tinted windows. The tower is occupied by Électricité de France (EDF), France’s main electricity company, and hosts company’s offices.
