I think it has a lot of solid surface to it (so not like the Mark,
unless the solid surface is glass spandrel (unlikely given all the corners?)
- so it won't look like a lot of other towers we have.
It will probably look "heavy", not "light and airy".
That's probably especially true of the east facade where it grows out and up. I think that the north walls of the "cubicles" are all solid surface - so when driving south down Howe, you'll see a textured, but solid wall under the overhang.
Also, when viewed at an angle, the recessed balconies may also create the illusion of a solid wall
- but there will be a lot of texture and nifty patterns.
i.e. step to the right a few steps in the pic below and from the new angle you wouldn't see any windows
(it have have the appeal of the back of the Law Courts, but with more texture):
