There still needs to be sufficient access behind the rear and side video walls/suitable walkway around the new set for maintenance.

Yes, we saw from the behind the scenes of the new Points West set that, ideally, you leave a kind of walkway/access area around the entire set just so you can access the panels from behind.

Of course, they had enough spare space to do that quite easily in Bristol.

It was also posted here a while back that one of the Look North sets (not sure which one, sorry) had a firelane all around the sides of the set and you could walk all the way around the back of the set. It was narrow, but enough of a space to fit into if you had to work on something from the back.

The camera blooper in a region the other week also showed that, where there is space to do so, the left side of the tower (as the viewer looks at it) has a proper finishing bit of set edging too.
