It is not about creating ex nihilo 
a new territory,
or a new city.
Surely not.
No.
Everything is out there and available,
but we can't see it.
The densification of a city 
cannot only consist
in building within a constructed space,
or in condensing areas
and making building surfaces more complex;
in other words, 
in consuming the void.
We cannot simply develop a city over the city.
We must also build the city under the city.
Action!
