In all honesty when I see that picture I cringe.
Whilst it does look fantastic, it's far to big for us, the end terraces do not need to be double tier.
What we need is the lower terrace of both the East and West stands to be joined up by having seating where the hills are. Where the corners in the Western Stand end now is high enough it just needs to continue around on both hills to join the Eastern Stand with coverd seating.
