Antiparochi+ is a fully private housing model that reactivates Greece’s empty apartments through exchange rather than rent, state involvement, legal reform, or monetary flow. Building on the historic Antiparochi system, the project operates entirely within the existing law of horizontal property ownership (Law 3741/1929), which allows individual apartments to be independently managed within fragmented ownership structures. Within this legal framework, usufruct rights enable owners to grant temporary rights of use and permit renovations without transferring ownership.

Antiparochi+ uses this mechanism to connect owners of vacant units with users willing to renovate them in exchange for time-limited housing access. Owners specify renovation needs, while users apply based on their housing requirements and renovation capacities. A standardized contract template structures this exchange by defining responsibilities, renovation documentation, maintenance and property tax obligations, and user protection through secured occupancy once the renovation work is completed.

To bring this system to people in a simpler and more accessible way, the project includes Mono-Poly-Katoikia, a board game based on Monopoly. Its name combines the original game with the polykatoikia—the dominant Greek housing typology produced through the Antiparochi system— translating Antiparochi+ into a hands-on experience of negotiation, matching, and exchange.
