Nothing in this world is more simple and more cheap than making cities that provide better for people.
Make it nice where you are, and put the density on top.
First life, then spaces, then buildings - the other way around never works.
A good city is like a good party. People don't want to leave early.
An endless number of green buildings doesn't make a sustainable city.
A good city is like a good party - people stay longer than really necessary, because they are enjoying themselves.
