I'm surprised these haven't hit the press yet that I can tell, they certainly look "finished".
Here is an illustration of the new HUP Inpatient tower with the museum on the left and part of the existing Perelman complex on the right.
This one is closer and shows some of the inside, with the museum still on the left.
This shows what the inside may look like, from the inside with museum on the right.
This one shows how the walkway between the new tower and the brick museum will be done up so people can walk from and to the train station.
A night-time view that shows how it would look with Smilow and the new CHOP ambulatory tower in the same view.
Cheers,
