Approaches to reuse vacant, obsolete or underutilised spaces

investigación innovación I+D+i desarrollo tecnológico europeo. HORIZON Research and Innovation Actions Expected Outcome: Project results are expected to contribute to all of the following expected outcomes: An increased number of local authorities systematically identify and quantify vacant, obsolete or underutilised spaces for reuse in neighbourhoods [1] in a context-sensitive way to address local community [1] challenges and needs. Increase in renovated, renatured, or converted spaces that address local community challenges and needs. Scope: Europe’s housing needs, inefficient use of the existing building stock, environmental commitments, and the EU’s goal of “no net land take” by 2050 make a compelling case for reusing the significant number of existing spaces, including buildings and infrastructure, that are vacant, obsolete or underutilised. In Europe, there are, for instance, an estimated 19,000 km² of underutilised brownfield land and 300 km² of vacant or underutilised office space [3] . The reuse of vacant, obsolete or underutilised spaces, following circularity [1] and sufficiency principles, can help address community challenges and needs thanks to their typical proximity and connection to essential infrastructure and services. While vacant, obsolete or underutilised space
