Adding the north stand added 7,000 to the previous 42,000. The north stand extension included one corner as an extension too. If the same is done to the south stand then that should be at least another 7,000 (the back of the north stand was restricted due to the proximity of the pool behind it) taking us to 56,000. That would leave the longer east stand and two corners so adding that would add more than 7,000. I would estimate it would add 11,000 to 12,000 so if the upper bowl was completed we could end up with 67,000 to 68,000 seats. I’m not an architect btw - just did some calculations years ago
