The city of the 20th century was a city of large numbers. It is what industry on modern urban planning had been responding. The city of the 21st century is going to be one of climate crisis, which is also a crisis of space. Many municipalities today are announcing that we have to stop building to just insulate and reduce the carbon impact of dwelling. But there will be 20 million new habitants in France in 2016 and we are building now only 40% of the number of homes that should we built. It will be an enormous problem. 

We know that a decrease in urbanization will never meet the demographic increase. We will not succeed in making a city habitable and sustainable with standards and figures. We must make an urbanism of space. How far apart to place two buildings, that is what the urban planner must know how to answer, depending on the place. This question of spacing, a central spatial question for making a city, is immediately social. The architecture of space can make density happy. This question of density is physical. Space is the medium in which we live together.

Our history of cities has been so old now. All the cities are yet built on even the peripherical system which is full of project. There is no totally empty space. Everywhere we have a site and the architect ask to respond to it. The future city, future dwelling in an ecological way ask to take care to this in between space that in the site the possibility to plant, to make garden, to have right dimension, to open this outside space that we need which are so important in the claim for space and city during the pandemic.
