or 387 m (or 213 m) allowing for a height of 194 m (58
stories) for L/H = 2 or 213 m (64 stories) for L/H = 1.

Situating the towers closer together is thus accompa-
nied by the reduction in length, volume and head losses
of the various networks serving the inhabited volumes
at the exception of the head losses of vertical transport
of materials, continual technical progress reducing their
impact.

For an equal density, the ground footprint is reduced
by the height, leaving the ground available for nature
and cultivation.

The isolated tower and the development of vertical
neighborhoods

The theoretical developments above allow us to unders-
tand the manner neighborhoods of housing, offices, and
mixed-use space were created, planned and developed
in Manhattan and in Chicago. It is on the basis of the
L/H and L/B rules that the first regulations, defining
the authorized dimensions to ensure the habitability
of high-rise buildings and the urban space, were esta-
blished at the beginning of the 20th century to create, in
this “new” world these first two vertical neighborhoods
on the planet.
