Thanks! I found your post and eventually found the permit on durham open data. Doesn't seem to have much in the way of details regarding how this fits into the plan(s) submitting and approved last year.
For some reason I thought they'd decided to go the "garden apartment" model for the plot closer to Elizabeth St(

Maybe that's changed, or maybe this application is vague enough that this could be, instead, for the tower side redevelopment. Either way, exciting to see this moving forward!
