I'm pretty sure it's the same size as all the others, just a bit lower due to the restricted grid height.

I'm confident Birmingham's is bigger, oddly, despite always being referred to as 'tiny' or small. This looks far more cramped than theirs, the desk/sofa seems far closer to the monolith.

Height not just being the limiting factor, the grid is low at TW because the space is converted office space, I had previously posted a structural plan of it. BBC English Regions were going through a rather experimental phase when SET launched and they had much the same corporate set at the time but rotate the view 180 degrees and you'd see the newsroom. Over time they built walls to create an enclosed studio for one reason or another but the converted office space doesn't change. Just a lick of black paint, stripping back the ceiling tiles and internal fabrication and a new wall with soundproofing - it's still an office.
