The EUNIC project "IF - Social design for sustainable cities" in which the architectural trio Traumnovelle is among the 60 projects nominated for the prestigious European prize. As a reminder, at the invitation of the General Delegation Wallonia-Brussels in Warsaw, Traumnovelle had participated in this conference in October 2020. This joint initiative of the EUNIC Warsaw Cluster and the Polish-Japanese Academy of Information Technology in Warsaw aimed to highlight ecological urbanism as well as the theme of sustainable cities and communities. It also aimed to promote pro-social urban planning, the role of culture in the creation of a common future, and the involvement of representatives of different backgrounds (educational, scientific, cultural and administrative) in the debate on the urban spaces of the future.
