The hub *might* have become called "Crossfield Mental Health Day Centre". On the other hand it might be that was its old name. Kind of more likely but then again camdenhub twitter account stopped in 2014. I'll try tweeting to find out https://twitter.com/harry_wood/status/839890852268949504 but ideally this needs survey

Among other unreliable looking bits and bobs on the web, the Camden Council open dataset on polling stations lists it as "Crossfield Day Centre" http://harrywood.co.uk/maps/map-my-data2.html?url=https%3A%2F%2Fopendata.camden.gov.uk%2Fresource%2Ftdwv-zwut.json

Also note that this currently has a missing mental health tag FIXME

I hit delete of some old data around here, because it's all just a big new housing development construction site, but I wasn't 100% sure this bit. www.openstreetmap.org/relation/2957349 We could check if there's still some visible "access shaft" on the surface here, but I don't remember seeing anything other than a newly about to be opened pedestrian area. Here's a photo looking eastwards from Pheonix Place: https://www.instagram.com/p/DGvSVA3ttNS/

This whole area is a construction site for a big new housing development, but it's nearly finished. Nobody moved in yet, but I think bits of it might be opening up for pedestrian access. Anyway I deleted a few surface level roads/footways which were out of date, but there's some weird stragglers here which I guess no longer exist.
