This high-rise office building stands over the Outlying street of Paris. The perimeter façade system is conceived in a timber woven truss bearing structure, achieving a column-free interior space and allowing a total modularity and flexibility of the floors layout. The floors are composed by modular wooden slabs. The glass façades are treated in order to be responsive to the day light, increasing the visual transparency of the building according to the sun exposure. The design is in order to keep the harmony and to have a clear identity in the environment.
