My personal Eden would be be very modern, with buildings and technology mostly like those you would see in any average - large city. The biggest difference in the cityscape would be that there would be much more green space, especially downtown. The people would be respectful to and mindful of one another. This place would be functionally bilingual at the very least - not only legally bilingual. It would be a very multicultural place, and the temperatures year round would vary from around -20C to 20C. There would be a few mountains very near the city to one side and rolling hills to the other.
Oops, not many visuals here - sorry.
