Getting High Wealth Residents and Businesses
Water Coverage
If you want to attract high-wealth residents and businesses, you need to supply water to your city. Without water, no high-wealth residents, offices, commercial services or high-tech industries will move into your city. To water your city, place water towers and pumps, then lay a network of pipes.
Education and Jobs
Why build schools, libraries and other educational buildings? Because that´s the best way to attract high-tech industries. High-tech businesses won´t move into your town unless your workforce is well-educated.
Health and Workforce
Why build clinics and hospitals? Because the healthier your population, the longer their lifespan. And the longer your Sims live, the more people who can work at jobs, which means your workforce is larger.
Getting Skyscrapers
You need to build your city wider before you can build it taller. The size of the buildings that you see are directly related to the population of your city. So even if you have high desirability, if your city is too small, you won´t see skyscrapers. For example, to get the tallest residential buildings, your city must have a population greater than 30 thousand. Likewise, to get commercial office high-rises, your city must have more than 45 thousand commercial jobs. In addition, your city must have zoned areas with very high desirability.
