Energie 360 ° wants to optimise its headquarters in Zurich-Altstetten sustainably and supplement it with a new building. The study contract from the department of structural engineering of the city of Zurich has now come to an end. The jury unanimously chose the convincing project “balance” from the work group around jessenvollenweider architektur and architekturbüro bosshard und partner. “With its slim expansion, the building looks elegant and gives the existing buildings a face in the new built railway station district.” Lüchinger + Meyer supported the planning team in function of the responsible structural planner. The success for our office is much more than “just” a won study contract. It is rather a fantastically prospered project history Lüchinger + Meyer already planned and realized the construction of the existing building during the years 2000 to 2003. The restoration and enlargement has now been the subject of competition.
