The building follows the straight line of the tracks on the north side and the curve of the Rue Crêt-Taconnet on the lakeside.

Situated on the Neuchâtel train station plateau, the building is shaped to match the straight line of the railways on the northern side. On the southern side, towards the lake, it follows the curve of Crêt-Taconnet street. As a result, rich spatiality emerges based on this duality between the straight line and the curve, clearly noticeable at the various interior atriums level. Integrating multiple sustainability considerations, this realization is characterized by the increased use of natural ventilation, passive cooling and high energy performance (100 MJ/m2/year of thermal energy and 200 MJ/m2/year of electric energy, including calculation center).
