Which would you prefer? 3 tiers as in the photoshop picture below or a 1 large stand similar to the KOP?
You would be able to make both ends 3 tiers high, but if you wanted one large stand, you could only do that at the North stand as there isn't enough land/space at the South Stand.
Either.

or a stand silmilar in size to what was going to be the new KOP. (not shape)
How it could be done. (With a roof added of course.)
