Renovation on Vanderbilt

I've noticed it a few times and a reader recently called it to my attention - the carriage house that used to house a preschool, and that was once a candy workers' union, is undergoing a rehab inside: whats up in the space on vanderbilt next to the yellow carriage house -- looks like a new school or something? betw, dekalb and lafayette.

For some reason, I assumed it was a residential renovation.  I thought maybe I saw it on Brownstoner, but I couldn't find it just now when I did a search.  Anyone know for sure what's up?
