The resulting designs could be fed through a variety of simulators, environmental, social, construction feasibility, etc.

One could also use a supervised classifier and have people rank the resulting designs. They can know what they like, but not why.

One could be cheap and use something like "The Sims" for evaluation and then optimize building that are possible to build there.

You would probably get more realistic buildings due to the different constraints on them.

I don't think the results should be taken to serious, but I imagine it serious fun to see them. xD
