In Lisbon, Portugal an organization designed, produced and installed what they call "Solidarity Lockers": https://www.csmonitor.com/World/Making-a-difference/2014/0124/Duarte-Paiva-helps-the-homeless-by-designing-lockers-to-house-their-things https://www.csmonitor.com/World/Making-a-difference/2014/012... Apparently it cost about 5000€ all-in, including installation, though manual labor is relatively cheap in Portugal. That said, I'm sure there are extra costs (at least in volunteer time) keeping them up, and that's often disregarded by these feel-good articles.
