Just to add to this. We (1894) have emailed our contacts at the club asking for an urgent meeting to discuss the plans.
The proposed hospitality sections would instantly end any plans of an atmospheric home end.
Just a side observation. It is a colour, on a diagram, in a design document. Could be from an earlier process, could be current, could mean exactly what it is or not that much. The seats themselves and the area as a whole doesn't appear to be shown any any different so it comes down to an admission choice more than design as such. Which may not always be a set thing. It isn't distinguished on the formal drawings as far as I can see.
Not really making a specific point nor should it affect your discussion. Just pointing out it doesn't appear to be an obvious set designated hospitality area. Nothing stopping it being used as such, but nothing stopping any other area either.
