Pardon? Have you misread? Simply saying a little tier over the north that joined the middle tier of the west would look good. But maybe not structurally possible.
I really hope they do. Would make the stadium look so much more finished & balanced. That gap in the north east corner and the grey space above the north stand looks like such a mistake in the architecture.
The dream for me would be that this gets built and can incorporate Dicks bar, they remove entirely or move the police box to the north east corner, and in doing so it gives them the room to build a proper north stand upper tier with the necessary concourse. We can but dream...
