Costs dictates that the seats are left exactly where they are, also being the away end, you need to make provisions that allow less able fans to be seated. Areas of terracing built up behind can cater for those who wish to stand and create a big match atmosphere.
Benefits are that while in league 1 you can divide and have a shared south stand and use the overflow for extra visitors if available.
Expanding the North in the same manner can commence at a later date in readiness for the Championship.
Not sure why you are quoting me there talking about the away end when I am talking about the home end. Let's talk about specific costs when they are actually produced. I've actually lost track of this thread now lol.
Oh yeah the ground could probably be expanded a bit and just waiting to hear what Thomas & Bower's plans are going forward. That's about the long and short of it.
