Piuarch takes part in the "Urbanfile for Milan" charity initiative, which involved some of the largest architectural firms of the city in the creation of a collection of t-shirts representing personal graphic contributions by the architects. The proceeds of the sale will be entirely donated to the Mutual Aid Fund of the Municipality of Milan. Piuarch has chosen the sketch of the new Human Technopole Foundation building intended for medical-scientific research, winner of the first prize of the international competition and emblem of the post-Covid future of the city of Milan.
