Creating a building design such as green urban infrastructure is something I’d want to incorporate with either solar panels, or vegetation within a high-density urban city such as Chicago. Hopefully one that can withstand the brutal winters. Enclosed green areas? Warming solar panels? Etc. This could be able to house itself as its own little town such as the last image which is an iconic building in Chicago consisting of parking garage, residential units, grocery stores, dry cleaners, bowling alley, etc. all within this one building; it’s an entire other town.
