Over the XX century a great number of cities experienced unprecedented
growth of population and expansion of their territory. As a result of this process
peripheries of many cities became occupied by shantytowns and urban sprawl,
faceless and often unstructured settlements. The main aim of the present work
is to define a possible way to improve such deteriorated urban environments by
the example of the city of Santa Coloma de Gramenet located in Barcelona
Metropolitan area.
Santa Coloma de Gramenet is an explicit example of a city that underwent a
stage of fast uncontrolled growth. Due to mass immigration to Catalonia that
took place in the second half of XX century this city housed numerous families
of industrial workers. Acute demand for affordable housing caused burst of civil
construction during which surrounding territory was intensively urbanized.
Developers working here were acting independently, without any kind of
coordination, not taking in account the city as a whole, hence collective interests
were neglected in favor of private ones. As a result of such unrestricted growth
present Santa Coloma lacks unifying structure, it is a territory without a model.
The urban fabric of Santa Coloma consists of numerous patches characterized
by different grids and patterns. Tension between patches with different grids
produces conflicting areas - points of discontinuity, areas where urban fabric
loses coherence and open space is presented as a merely residual land left
after urbanization.
In order to improve urban form of Santa Coloma we propose to affect exactly
these points. We propose to create in these deteriorated areas a net of local
centers by inserting there new buildings with diverse programs. These centers
will become places where citizens are able to find different public services and
amenities within walking distance. Moreover, each center will acquire certain
identity and character by creating an impressive public space, a scenery of
social life. In order to elaborate conditions generating identity we examine urban
space as a combination of its elements. After definition of basic constituent
parts we try to formulate a pattern of characteristics that would be presented in
each of local centers. This recurring set of signs will endow urban space of
Santa Coloma with recognizable familiarity.
As a result of this transformation the city of Santa Coloma will obtain
distinctive identity and will become more meaningful for its citizens. The network
of new urban spaces will facilitate navigation and give the city a clear image.
Facilities concentrated in new nuclei of urbanity will promote social interaction
and encourage creation of tight-knit communities. Generally the set of aforementioned measures is intended to change existing peripheral status of
Santa Coloma and to turn it into self-contained urban entity.
Nowadays in developed countries dynamics of urban expansion slowed down
whereas improvement of existing environments is becoming primary objective.
Considering this, the strategy and methods of transformation for shapeless
areas will remain relevant for future development of peripheral territories
throughout the world.
