This thesis in proposes a comprehensive framework for German authorities to implement participatory budgeting. The focus of this proposal revolves around enhancing the “Haus der Statistik” building, either by adding a new building or enhancing the existing one. Two key directions were considered: social and ecological aspects. For the social component, interviews were conducted with professionals involved in the project, including designers and stakeholders, to gather valuable insights and ideas. On the other hand, the ecological aspect involved two options aimed at calculating and reducing the CO2 footprint while ensuring measurable results. The perspectives and opinions of the general public were also sought, allowing for a combination of ecological efforts with social considerations in the initial design phase.
