Yeah I posted this idea before but people seemed to miss the point thinking that I was talking about extending the stands rather than completely replacing them with brand new structures, the existing stands would still be part of the building, just hidden and potentially not used. The conversation will go around in circles indefinitely because we all know that the only things to happen will be continued improvement of food offerings, new external cladding, the ability for kids to run on the pitch, and if we're really lucky other coloured seats. None of which is addressing the issue.
When you build it you could rotate the pitch 90 degrees, put up Hutt Rec type temporary stands on one side and build the new stands on the other, therefore still using the existing stadium during construction at a greately reduced capacity.
