In the name of colour and sustainability: these were the priorities for the redevelopment of the Bruno Munari Garden in Milan. The garden in Via Toce, long vandalized and neglected, has come back to life with the sole use of color that, beyond aesthetically redeveloping the degraded area, adopted green urban planning interventions. In the process were involved the Korean experts of Colorful Intelligence Noroo Milano Design Studio, who used special paints with anti-smog nanotechnologies capable of reducing pollution density by 89% (equal to the activity of a 300sqm wooded area). Therefore, the redevelopment not only made the garden more pleasant and creative but also improved the air quality of the surrounding area. The chromatic interventions recreated different environments within the garden: a corner wall has been transformed into an area dedicated to children, a series of painted trunks form a sort of “trees behind trees" labyrinth, a service shed became the canvas for an abstract urban landscape, and a network of ventilation pipes turned into a colorful urban sculpture. The activity was commissioned by Associazione WAU! Milano and created with the support of the Maurizio Fragiacomo Foundation.
