At
the centre of the current urbanization of the communes of the Boucle
de Chanteloup are two recurring motifs in French
periurban development: activity zones and detached housing. If
this slightly low-quality mode of urbanization presents certain
difficulties in terms of economy and urban space, it remains
nevertheless frequently used for periurban planning, and seems to be
the only alternative to certain extensions of communes, responding to
real housing and employment needs. In this context of in-between, it
seems to us appropriate and also realistic to propose a new kind of
urbanization making use of these two inherent motifs of present
periurban development.
The
project is therefore founded upon the same elements used in the
recent extension of the communes of Chanteloup-les-Vignes and
Triel-sur-Seine (activity zones, individual and semi-collective
housing, parking spaces and road networks) but articulates them in a
new way in order to discover a new kind of urban living which also
represents a higher population density.Horizontal
superposition
:
The
search for integration generally implies a spatial cohabitation
between several programmes. In dense towns, this
mixity often takes the form of a vertical superposition of functions.
In periurban towns, this vertical superposition raises the question
of the ownership of the land, of constraints, and of the dependence
on each other for their own development potential of two contingent
programmes. Periurban
towns seem therefore linked to a horizontal development more often
than not perceived negatively as taking
up a lot of space and network. But this horizontal urbanization, with
the principles of density and mixity applied,
potentially contains the essential qualities of the periurban town.Mixity
= sharing :
This
principle of horizontal stratification relies on the multiplication
of blind façades, both the detached housing and in the activity
building. A reorganization of the active façades of the buildings of
each programme allows us to place them back-to-back with each other.
A
bicephlous block appears:-
The interior of an open block where all of the parking space is
concentrated as well as the façades of the activitiy buildings
visible from the road
-
A layer of housing, extended by private gardens, surrounding the
activitiy buildings and the courtyard and helping to landscape the
public space.
This
integration leads to a sharing of the main road, the
parking space and the façades and thus contributes to making the
project more economical: economical in its road network, economical
in its construction, economical in its energy consumption, and above
all economical with space.
The
horizontal integration has a second advantage; that of flexibility.
Since the two plots of housing and activity buildings are effectively
distinct and separate, it is easy to imagine the evolution of one
without any consequence for the other.
