This document summarizes work from the COST Action RESTORE CA16114 project, which is supported by COST and the EU Framework Programme Horizon 2020. It describes the four working subgroups focused on regenerative procurement, construction, operation, and future life. Each subgroup conducted a literature review and case studies, identified gaps, and will contribute discussions and findings to the final report to further understanding of regenerative approaches within their respective areas. The overall aim is to advance sustainability across the full life cycle of built structures.
