The building is designed as the closing part of Gae Aulenti square, in Porta Nuova Milano, it is composed by the superposition of two tapes, one continues from the square the other one move upwards. The lower body takes the alignment of the surrounding buildings, it is oriented on the main axis. The change in the rhythm of the vertical elements of the facade creates different levels of permeability. The green courtyards and the green square/botanical garden, improve comfort of interior spaces and workplaces, contributing to bioclimatic welfare.
