I noticed there's a small amount of balcony glazing on east side of the north tower when walking by earlier. Looked pretty generic. Clear glass and white railings. Hopefully they add those precast brick sections from the renderings to cover the concrete at least, might make it a bit less mediocre.
just a reminder that the SPA application called for Brick / Terracotta / Aluminum guards for the red portions. As they did not cast anchors for precast panels into the slab edges I would assume brick is off the table for the tower.
