The possibilities are endless. I don't think that anyone should get too caught up in the current rendering but instead think of what most people would like to see in a stadium but base it on an economical design. The only way that I can see of keeping the cost down is to think of ways to make the design as simple as possible but with all the desired features - sufficient washrooms, sufficient interior circulation space, adequate emergency exits, good sight-lines, etc. It would be good to have a per seat cost of no more than $2000 per seat (that is the cost of the entire stadium structure divided by the number of seats). I think that it should be a modular design which is built in a similar fashion to a multilevel parking garage.
This is a simple design (below) which I think will work well in the Halifax area. There could be a couple of levels of interior circulation space that can be used for washrooms, concessions, stairways, luxury boxes, wheelchair access, etc. I think it is best to keep the changerooms, referee rooms and even VIP in corner buildings that can be expanded as necessary. In some cases a sunken design may not be the best choice so I am doing one that is not sunken (however, if the land is naturally hilly then the land can be partially used as ramps, instead of specially built exit ramps which require a lot of space).
