Brussels - Flanders : a separation
sample
At the edge of the Brussels-Flanders border lays a landscape of incongruities and of opportunities for redesigning the city of the 21st Century. The administrative border between the two regions is intermittently enhanced by the presence of physical boundaries determined by topography, infrastructure and conflictive monofunctional patches. Built at the time of welfare apotheosis, they overlook valleys and embody an urbanism of heroic modernism. Nonetheless, the densities and complexities present in most of these intensive dwelling environments have something to say about Brussels’ future condition: an intense and mixed metropolis that requires re-configuration to meet its forthcoming challenges. The lack of social mobility generated by unemployment and by the pervasive state of precariousness, besides being a symptom of weak democracy, might increase the present condition of sociospatial segregation, worsening the degradation of those areas of the city where weak and poor individuals coagulate, looking for reciprocal support. The design studio will address large-scale social housing estates as sites of opportunity in the changing urban settings of both Brussels and Flanders. Brussels is growing and the Belgian capital will fall short of housing its expected inhabitants. From this premise, the studio will focus throughout the semester on the elaboration of fundamentally critical questions considered foundational for the development of grounded design strategies.

The border of Brussels, capital region, with Flanders is, at first glance, physically non-existent in this researched sample. Within a moment’s notice you traverse from Mutsaard into Strombeek. Not until approaching the center of Strombeek you become aware that, even though typology slightly transforms from city to village, it is identity that forms friction. Enclosed by infrastructure, Strombeek evolved in a way that resembles Brussels, even though it is a part of rural Grimbergen. Next to those highways large scale functions like the Heizel, the park of Laeken and the soccer stadium also act as borders to this region. These infrastructural borders actually had a positive influence on the sample. The separation allowed the territory to evolve in the same way a village does with it’s related functions inside the fabric. It developed functions that attract people from various regions. In this archicomic four students try to give a voice to the different identities that make up the site in and around Strombeek. These identities not only include people but places and constructs as well. Find out whether or not thay relate and whether or not they should.

Tributaries
Floodplain introducing São Paulo São Paulo is full of dichotomies and contradictions. Regarding urban form, everywhere, everything seems to go vertical whereas the city presents itself as an urbanized horizontal carpet. Its center is marginalized whereas its margins are occupied by booming centralities. Real estate led redevelopments have destroyed well functioning neighborhoods and replaced traditional housing typologies, yet the city still has 30% of its housing units in some kind of informality and precarious living conditions. Mobility infrastructure provision has been deficient over the past years and the current system is inefficient,yet it involves around 23 million travels per day, each day. The city presents itself as a powerful concrete jungle, yet it, has to surrender regularly to the forces of nature.
water network in the midest of Sao Paulo terrain and area under studio intervention
The infrastructural crisis offers the opportunity to work with landscape rather than against it, interacting man-made forces with natural ones in a more sustainable way. By using the River Pinheiros and its surrounding neighborhoods as cornerstone sites, the studio proposes to unravel the megalopolis’ dichotomies by exploring possible new relations between infrastructure and landscape.

highest concern was raised to solve the ongoing crisis related to water; with flood risk, lack of proper drainage-sewage and potable water shortage worsened by the canalization of the water network
the horizontal spread of the city and infrasrtructural shortage to connect vulnerable areas was seen as another problem to achieve efficient urban life.
Fragmented and patched urban tissue of the Megapolis of Sao Paulo shows a complex matrix that combines diverse landuse with varied social strata.

in - between ___ The floodplain: Industry belonging of the private realm
Zooming into a regional scale from Campo Limpo to Santo Amaro, two sub-municipality, the patchness and isolation of city quarters were studied from grass root.
Here in particular to provide linkage the roads, the surface rail and metro, infrastructures slowly occupied the valley and floodplain resulting a funnel effectdriven by the topography.
Along with the patchness and linerity of mobility networks the water bassins without sewage, continious pollution and garbage disposal deteriorated the environmental situation greatly.

Schemes for interventions
Phase 1 : management of problems related to water
> Introduction of sewage in vulnerable areas
> Introduction of drainage in areas in flood risks
Sewage dispersed into river. Contaminated river.
Buildings on natural creeks. Impermeable ground. Flood problems.
> Provide drainage network and percolate rain water Relocation of threated houses
Opportunity to improve the streets.Pavements & bike paths.
Percolation of storm water

> Top priority was given to water related problems in the urban sao paulo and several schemes was developed to overcome flood risk and envision solutions regarding drinking water shortages.
rain water catchment
> Provide sewage system in vulnerable areas

Phase II : enhancing the natural existing ecologies
> Following the logic of the water bassins
> Reversing the image of the in-betweeness > Using rain water for irrigation
> sub hydrographic basin 01 860000m2 255 l/m2 >water tank min= 2193300 m3
> Next step was the enhachement of previously deteriorating natural ecology through critical intervention of water bassins and reuse of storm water in community based agriculture that can refuel the economy of the vulnerable inhabitants.

Phase III : activating public realm
> Reorganizing mobility
> Conecting vulnerable areas
Creating multi modal nodes for public transports
> Lastly a sensitive concept was developed for the betterment of the public real introducing new and efficient functions for the neighborhood as well as reinforcing the local economy along with a coherent mobility network.
