Here's another go at my idea for rotating the pitch 90 degrees at westpac and building two new stands blocking off the old ones. I found a model of the ring of fire in sketchup online, I've never used sketchup before so forgive how crap it is:
Top down view, you rotate the pitch 90 degrees, its aprox 120x70m it might be a bit close to the stands though so the first couple of rows may need to be demolished. You build two new stands as completely independent structures with their own roof, completely obscuring the old stands, but integrating into them visually.
The space behind the new stands are aprox 50x120m, although not very useable it could be event space of a venue space.
A view from inside the stadium, the curved stands at either end of the pitch are the original stands, the straight stands along the sides are the new ones that (as I said) completely obstruct the current end stands.
Another view of the new stands.
Yet another view, this is from the existing side stands (which become the end stands) and looking at the new stands.
This is behind the new stands, not very usable but you could potentially put a stage in there for an indoor venue (espeacially if you can demolish some of the old stands, otherwise it could be exhibition space, lecture space, bars, etc.
