Expansion of the stadium could cause disruption. A simple ‘add a third tier to the North Stand’ should cause no problems. Anything beyond that would.
in particular the ideas being bandied about on here for a large single tier for the North Stand would shut the whole end for a sustained period, maybe a full season? That would cause mayhem for existing season ticket holders.
I suspect that the least disruption would be provided by starting work at the end of the upcoming season. A lot of those who are likely to defer this season will probably not renew. That could give the scope to shuffle people around. I will be surprised if anything happens.
