The city of Sint-Niklaas (Flanders, Belgium) launched a call “Treat yourself and your neighborhood to a free green facade” in 2021, within which residents can apply for financial and technical support in creating green facades on their property. The goal of this action is to create green, pleasant and climate-proof streets through green facades to reconnect the city and its residents with nature. The city collaborated with a non-profit organization “Groene gevels” to plan for, involve residents and implement sustainable green facades (e.g. through the use of sustainable materials to provide a frame for climbing plants to grow on). After a technical and safety check of the location by the NGO, a participatory approach is applied in which residents are involved with the design and management of the green facades. The construction of such a facade garden is completely funded by the city; however, the residents are expected to be responsible for its maintenance.
