What will the internal atriums look like?

It's my understanding that Harbour Mill will have two large atriums - the main one where the four lifts are situated, which will be open on the east and west sides to allow ventilation.

Plus another in the four-storey part of the building, rising up to a glass ceiling, providing light into the more southerly part of the structure. This is the plan for that atrium. Very handsome (I think).

And those apartments on the lower level looking north will face the old flour mill, like this:

Since my apartment is not in that part of the building but I'm curious what it is like, I'm hoping to get a look inside one of those apartments some time.
