Tour Alto is the tower that will help to transform the face of the Défense in Paris. Designed by Jean-Philippe Nuel for IF Architectes, with Sra Architectes as executive architect, the tower, 150 metres high with 38 floors, will house high-class offices, with a total surface area of 51 thousand square metres: a masterpiece of architecture, sustainability and technology, combining aesthetics and functionality. The project is part of an evolution and animation plan for the district: this building, characterized by flexible and elegant forms, renews the architectural environment of the area, in contrast with the geometry and linear forms of La Défense. The stimulating, multifunctional, comfortable, rational and bright interiors promote social well-being and inspire creative excellence, conviviality and productivity. Inside the offices, POST chair has been included, which can combine elegance, simplicity, technology and creativity in a single product.
