The contemporary project of the tall residential building, between density and intensity

The essay investigates models and techniques of intervention for increasing the urban density, illustrating how the tall building can be a still useful device in the densification processes, and what circumstances it should face also in relationship with its evolution in the European architecture of the XX century. Several recent case-studies allow to highlight the role of the technology, addressed not only to overcome height limits, but also to actuate regenerative operations on existing tall buildings, and the necessity of associating, to the increase of density in the urban fabric, the development of an intensity of uses and relationships that can arise and intertwine in it.
