B looks a thousand times better for having the fake workstations up on that top level. I think it’s why it looks so much like a warehouse normally because it usually just walls.

Basically, what's needed is a dash of colour and a bit of 'activity', otherwise it does, as you say, just end up looking like a sterile news warehouse. It's a bit like the old TC7 Barco set in that respect - what exists is a not particularly exciting base; it will look best when you find ways to meaningfully enhance it (as Newsnight, Working Lunch, Marr were better at). Leaving in borderline default mode, as Breakfast and the Six used to do with TC7, doesn't end up showing the space off in its best light.
