CityPlug is designed to create value in unused or overlooked spaces within the city. Many urban areas have empty lots, unused buildings, or underutilized communal spaces that currently add little to the social, economic, or environmental life of the city. At the same time, the city is a complex system of streets, houses, offices, shops, green areas, and infrastructure. CityPlug is an AI-driven platform that maps these hidden gaps and generates tailored options for filling them with valuable functions. The system calculates the available square meters, the potential costs, and the possible returns for the community. These functions could range from social and cultural spaces to housing solutions, green interventions, or community facilities. What makes CityPlug unique is the collaborative approach: it connects municipalities, developers, and residents to decide together how these spaces should be transformed. By turning overlooked voids into active places, CityPlug gives something back to the city—strengthening social cohesion, supporting sustainability, and creating opportunities for economic and cultural growth. CityPlug reveals and fills the “invisible gaps” of the city, turning them into meaningful spaces that respond to the actual needs of urban life.

The Problem Modern cities face critical challenges: Vacant buildings stay unused for years, while housing shortages rise. Empty plots and leftover spaces between roads, railways, or rivers remain unused, creating safety risks or visual pollution. Underutilized communal areas in housing blocks or office buildings stay locked or neglected, missing opportunities for social cohesion. Climate pressure demands more green space, but land is scarce and not well-mapped. Municipalities and developers often lack data-driven tools to identify these gaps or to evaluate cost-effective solutions. Our Solution CityPlug is an AI-driven mapping system that detects and categorizes underused spaces in real-time. For example: A vacant office floor could be repurposed into affordable studios or co-working hubs. A neglected green strip between buildings could become a community garden or urban farm. An unused parking lot could transform into housing modules or a playground. CityPlug calculates available square meters, costs, and impact, and then presents scenarios to municipalities, developers, and residents. Together they choose the most valuable option for the city. By turning overlooked voids into meaningful places, CityPlug solves housing shortages, reduces urban waste, and creates greener, more inclusive neighborhoods.
