PARTI-CITIES proposes a citizen-centric model of urban transformation that integrates participatory governance, game-based decision-making, and advanced digital fabrication to address the social, economic, and spatial challenges of contemporary cities. Responding to rapid urbanisation, post-pandemic vacancy, and the exclusion of innovative communities from city centres, the project reframes urban development as a negotiated process driven by citizens, start-ups, and investors through a cyber-physical platform.

At the core of the system is a multiplayer participatory game that enables communities and start-ups to collaboratively envision, fund, and configure urban space. Using voting, investment, and operational phases, the platform translates collective preferences into spatial outcomes while embedding economic logic through tokenised currencies, smart contracts, and decentralised finance mechanisms. This framework allows users to directly influence urban form, programmatic distribution, and degrees of sharing between private, semi-public, and public spaces, establishing a transparent and scalable model of bottom-up urban governance.
