It's going slowly, but it has been moving. The glass facade has been dragging, so perhaps they're waiting on a shipment.
I wonder if getting rid of the crane early was a cost saving move.
I have to say I always thought this would be a huge turd but it has turned out really nicely. It, somehow, has good vertical lines. The glass certainly helps.
I believe the balconies are permanent and can be seen in the renders.
