As well as representing an opportunity to create a new workplace for Regione Lombardia, Palazzo Sistema is also a starting point for an urban regeneration process of the entire district with the direct involvement of the community that will become its main user. Arising from a horizontal urban dimension, the architectural complex culminates with a 26-storey tower overlooking Via Rosellini. The vertical development is emphasised by a backbone consisting of double- and triple-height green terraces visible from the outside thanks to modular panels of photovoltaic glass, which eventually finds its expression in a large garden on the roof of the low body. This uninterrupted relationship with nature generates a biophilic building where sustainable architecture and the quality of the interior workspaces promote the well-being of people.
