The new building will offer 30,700 square meters of office space over 23 floors. The tower is therefore a continuation of the Silex 1 project, a small office building completed and delivered on May 11, 2017.[3]

In 2021, the Belgian group Solvay, one of the leaders in world chemicals, will move into the tower and should occupy 9,000 m2 of offices, on eight levels.[4]
