Final graduation project at the Faculty of Architecture, Delft University of Technology, as part of the Urban Asymmetries Master Program, July 2009. This individual architecture project worked together as part of a bigger urban strategy, a communal project led by a group of ten Architecture and Urbanism students: Levan Asabashvili [GE], Bai Yan [CN], Silvia Bizzarri [IT], Carlos García-Sancho [ES], Tania Guerrero [MX], Tomi Jaskari [FI], Tom Kolnaar [NL], Phillip Lühl [NA], Willem van de Ven [NL], Siebe M Voogt [NL], Taufan ter Weel [NL] and Idan Zveibil [IS].
All these projects were published in the book "Urban Asymmetries. Studies and Projects on Neoliberal Urbanization", Ed. Tahl Kaminer, Miguel Robles-Dúran, Heidi Sohn, 010 Publishers, Rotterdam, 2011.
The project is set in Ecatepec de Morelos, which is the largest peripheral municipality of Mexico City’s metropolitan area, located within the Estado de Mexico. It represents roughly 3 million inhabitants (only 1.6 million officially) in the Metropolitan Zone of the Valley of Mexico (ZMVM), which is estimated around 28 million inhabitants.

"Invasive densities" is part of a group of architectural proposals, under the common title of "Proposing alternative urbanities", which aimed to propose a new model of urbanization in the periphery of Mexico City, exemplifying it in a strip of vacant land which runs between the recent low-rise development of 'Las Américas', and 'El Caracol', an old abandoned evaporation land.
General strategy of the urban plan and tentative plan of the first proposed development of the urban strip (bottom).
Three projects constitute the seed of the new alternative urban plan. From bottom to top, a dwelling complex + agricultural facilities (Phillip Lühl), a market facility + housing (Siebe Voogt) and infiltrating Las Américas fabric, the “Invasive Densities” housing project (Carlos García-Sancho).

Density of this new strip of land becomes a relevant topic: fabrics with higher densities were proposed, as an attempt to create a more sustainable type of urbanism, and defy the surrounding mono-functionalism. More density is not only more square meters built per area, but, as Teddy Cruz’s puts it, it is an amount of ‘social exchanges per acre’ [1].
"The lack of groundfloor space that the municipality of Ecatepec faces makes it imperative to search for ways to introduce higher densities, also ensuring a more sustainable use of public space per inhabitant, in which maintenance costs are reduced. In the bigger scale, to aim for denser fabrics means to try to stop Mexico City’s sprawl and reduce the problem of car pollution proposing a more pedestrian-friendly environment and scale."

"The production of 'social interest housing' (vivienda de interés social) in large parts of the peripheral municipalities of the Metropolitan Zone of the City of Mexico (ZMCM) creates extensive patches of low rise fabric financed with the help of the governmental housing structures (INFONAVIT and FOVISSTE). The speed at which these developments are planned and built is amazing: by 2005, 384561 dwellings were produced in 6383 hectares of these types of fabric [2] in the whole ZMCM. These developments provide individual houses with virtually no other functions, that lack a cohesive urban plan. Furthermore, the centralized clusters of commercial use that usually come together with them create serious social problems in a population that is used to other patterns of consumption [2]. Ecatepec de Morelos is one of the municipalities that faces the problem of managing and sustaining these fabrics, which have been built by previous governments, even though the official position of the government is to not authorize any more of these developments. Other aims of the municipality in urban planning include the implementation of higher densities, due to the scarcity of non-built land in Ecatepec."

The "Invasive densities" project proposes to infiltrate the existing open spaces of 'Las Américas' low-rise development with punctual developments of higher densities, which would also introduce other uses into the mono-functional existing fabric. Even though here proposed in a particular setting, this strategy could be carried on further in other parts of 'Las Américas', and in other similar developments in Mexico City's urban sprawl.

"The land left unbuilt in Las Américas development becomes public (municipal) after it’s finished. Thus, the municipality cedes some of this excesive non-built areas to grant the availability of housing, at the same time densifying existing fabrics. The municipality hires a constructor to develop this land, and through VISOMEX mediates between individuals who need a house but don’t own a plot of land. In exchange for ceding this land, VISOMEX can push for certain design features (higher densities, mixed use, introduction of public functions), This will be the framework in which the housing cooperative formed by applicants to the program will reach an agreement on the final configuration of the building. The construction of the houses will be financed through federal funds, administrated through non-profit credits withou interest. The Municipality is thus ‘privatizing’ some public land in order to provide housing, but at the same time holds control over part of the groundfloor areas, supervising their use and funding it through the local budget for promoting small businesses. At the same time, this productive and commercial activities in the groundfloor are aimed at providing facilities to the inhabitants of Las Américas at a local scale."

The upper floorplans tried to combine different modes of home ownership and typologies, while introducing collective shared spaces and facilities which aimed to provide extra communal space for the smaller rental dwellings.
"How can we operate in the already built fabrics of Las Americas, taking into account that the streets and roads are responsibility of the Municipality once these kind of developments are finished?
The aim of these (local) interventions in the Las Americas fabric (whenever possible) would be:
a) to provide housing through collective credential structures, that operate in a similar way to the Instituto de la Vivienda in the Federal District (State credit with no interests) in which the Municipality leases the public space in order to provide buildable land, but has a say in the design and planning of the units.
b) to sustain that housing in the future through a cooperative structure that limits the open trade of the units, and that creates a social bond between dwellers.
c) to ensure local densities above one square meter of celing per square meter of land, which is roughly the density of the existing city in the surroundings (the density of the Las Américas housing is of 0.6).
d) to provide spaces for local commerce to appear, controlled by the Municipality, that would try to cope with the problems that takes place now in Las Américas: dwellers giving up their living rooms in order to have a business. Shared property and rental facilities would be an option, through the local budget for promoting small businesses.
e) to provide, along with regular houses, other modes of living based in cooperative services (kitchen, bathrooms, laundry), which would be managed by the municipality and aimed at migrant workers of El Caracol, other migrants passing through Ecatepec, and families in situation of risk.
f) through this changes, provide a livable urban space, in which the street is no longer a road that only serves as connection an access, but really a public space with services and suitable environmental conditions. This could also alter, with time, the relation of the Las Américas units to their surroundings.
e) to oppose a different kind of living to that of Las Américas, in a municipal effort to make the fabric more sustainable, at the same time exposing “the appalling contrast between possible constructions of life and its current poverty.” [3]"

"The buildings will have, when possible, an average height of four to five layers, which provide space for two cuplex) with independent accesses to appear. The size of the units will be of around 65 square metes (the maximum size for social interest housing in Mexico) but will provide double spaces that can, in a future, and only if desired, be re-gained as an extra 15 square metes, which would then provide dwellings of 80 square meters (not including outdoor spaces)."

The project, in the end, tries to redefine public space in conditions of urban sprawl. By adding new uses and facilities, shadowed areas and a rain water reservoir ('rebosadero') to provide temporary climate regulation when possible, a more livable public space is proposed. The luxury is not having an extensive open space, but having one with the qualities which can ensure a certain urbanity.
