In order to tackle pressing societal issues, we must reconsider how we design and inhabit our neighbourhoods. The necessity of consistently including end users or local communities is sometimes overlooked in the planning, designing, and construction processes used today. However, combining community knowledge and initiatives can result in more liveable neighbourhoods that empower citizens and represent local needs and surroundings. Furthermore, the way public areas are constructed can have a big influence on how people interact with one another, what kinds of activities happen there, and how much trust the public has in their local government and democracy as a whole. The project seeks to rethink how neighborhoods are designed and experienced by emphasizing the importance of involving local communities in the planning, design, and construction processes. By incorporating community knowledge, more livable spaces can be created that meet local needs and empower residents. Public spaces are vital in fostering social interaction, trust in government, and democratic engagement. Equipping people with the tools to actively participate in co-designing these environments can strengthen social trust, enhance a sense of belonging, and boost community involvement. The "Sustainable Public Spaces through Inclusive Community Engagement (SPICE)" project aims to develop a participatory co-creation model for shaping neighborhoods. It will explore and test innovative methods to engage communities in co-designing and maintaining public spaces across diverse European neighborhoods. By promoting interdisciplinary collaboration, leveraging digital tools, and using sustainable construction practices, the project aims to address societal challenges, promote social inclusion, support democratic participation, and align with the European Green Deal and New European Bauhaus principles.
