Woody is probably a better source than I, but my understanding is that the Shewey Bldg is not made for any other vertical additions.
The MU Med school has one of the new boxes, as well.
That's the claim, they'd have to essentially build a new structure outside of the shewey to support anything on top of it.
It'll never happen, but since we never sell out, or really ever come close, I wish we'd tear down the endzone seats, and put in a club level seating area right there above the original rows of seats. Something like this at Colorado...the black seats are for Club Level ticket holders, there's a huge room behind the seats with tables, concessions, tv's, essentially a Big Green room where you can see the field, but if you want you can also sit outside in your seats
We could build the club level so that if we want to expand in the future, we can just add seats, real seats, above it. Don't put ourselves in a position where we can't do anything about vertical build on the shewey.
I was talking with someone the other day that's a bigger booster, and said if I had $2b to blow, I'd go to Marshall and say here's what we're going to do. Tear down the current suites/press box structure and build a new one. Build the first level as club seating (like the pic above) that goes almost the full length of the stands, then build a row of suites above that, then a third row with the coaches box, pressbox, with some suites on it as well. And build it so that if we ever wanted to add another level with more suites we could do that. Then we'll build closer to field level suites where the current green metal bleachers are in the one endzone.
