DUOPUU is photographing the main construction phases of a 5-storey ecological wooden building designed by Essepi for the University of Trento. The dorm will house 140 students from all over the world in the highest timber university building ever built in Italy. The structural elements are innovative seismic-resistant prefabricated 3D-cells totally made of XXL cross laminated wood. The 3D-cells built in the factory feature preinstalled Essepi wooden windows, acoustic-thermal insulation panels and internal gypsum board. They are ready to be transported on site safely and assembled together quickly by Collini Lavori.
