Is that Studio B Lewis Vaughan Jones is presenting in one of your caps above? If so I thought B was mothballed in between Covid and B being refurbished for the 6/10 last year.

They do more than just the 6/10 from NBH B. It's also the home of Laura Kuenssberg on Sunday,  Talking Business programme with Aaron Haslehurst and BBC London News.

I'm sure that NBH B is a technical marvel for those in the industry, but to the average viewer is looks as though they're broadcasting from inside an empty aircraft hangar and pointlessly walking around to show the space.
 
At least when ITV did the expansive 'Multi-storey Car Park of News', we new it was all fake apart from the desk (and people).
