housing and land use

What is the best way to use land in cities? There are many ways to grow a city and many factors to take into account but the way you get the most people having a good quality life is to have mixed land use with retail and semi dense housing. This enables everyone to live near what they need and provides a wide variety of facilities locally for people to enjoy. The fifteen minute city describes this concept. In the past we had communities live in denser housing and there was a sense of community. Combine that with access to everything you need and you have provided good quality of life for people. Vienna has lots of affordable housing and it comes up as the most liveable city in the world. You also need to consider having good places to go as that improves the quality of life.
