I've made a city, it's actually just a experimential city because I'm ***** and need to try some things out, so i made it in a small regionsquare. Anyways, the residential/commercial city is connected to an industrial city. My residential areas almost covers all of the map. I've built middle density most of it, and a few high density. Every area is 4x4 zone with each building being a 1x2 zone. In the middle I have elementary school, library, museum and the two schools following elementary (I play in swedish so I don't know the exact names in english). Health care, education, PD and FD covers all the city and everyones happy and so, and most of my population are middleclass people, with some high class aswell. In my industrial city I'm out of money, I just don't earn any money. I had a deal for power and garbage before, but I managed to screw that up :S. Anyways, here I have some hitech industries, alot of dirty, and a few farms. Now my problem is this: I need more citizens, but I've realized that I can't keep expanding like I've done so far. I'm thinking that it must be possible to build on the height. My commercial zones are almost exclusively middle class business. How can I improve my buildings to house more people and become scyscrapers? Really my question is, how do I improve my zones to house more people/become better commercial zones/become pollutionfree industry? All my rich/middleclass people just build mansion and crap Long and ***** post but I hope you get the idea!
