That's a nice marble-like wall on one side of the ticket hall. Except,
the thing is, the ticket hall is also supposed to be an entrance to
Crossrail, with the escalators going straight through that wall.

Is it just a "marble-effect" wall? It's many years before the Crossrail
part of Farringdon will open, so they presumably need something fairly
substantial to separate passengers from the ongoing works in the
meantime.
