Live Project

The Unionezero project in Sesto San Giovanni represents a major urban regeneration initiative in the former Falck area, combining mixed-use functions with a strong focus on sustainability. Within this context, Cluster 2, designed by ACPV Architects – Antonio Citterio Patricia Viel, will host next-generation office buildings.

Among them, a large office building for a leading banking institution – the subject of our contract – and a second multi-tenant building.

ACPV’s architectural approach stands out for its quality and innovation: flexible and bright workspaces, generous green terraces and loggias, and the highest energy and environmental standards with targeted international certifications (LEED and WELL).
