Tour First is a complete refurbishment of the 1970s tower designed by Pierre Dufau, which was one of France’s first skyscrapers. Originally conceived as three identical wings around a central core, the design retains the integrity of the original tower while providing a modern interpretation of the concept and vastly improving the environmental performance and internal conditions and circulation.

The new tower and podium reorganize the entry levels of the building, reinvigorate the entrance hall and improve circulation. Seven sky gardens are created in strategic positions and provide informal meeting and breakout spaces. The original tower was made taller, adding approximately 12% of additional floor space. The three wings are now of variable heights giving the building a dynamism that it previously lacked. The façade “fragments” into a composition of folded and transparent panels filled with stainless steel tubes or individual triangular glass pieces.
