urban think tank: grotão fábrica de música

international studio urban-think tank presented their creative practice as speakers of this year’s design indaba conference in cape town, south africa.
their research and development approaches architecture from a humanitarian standpoint in which the trajectory of their work over the past decade
has been aimed at increasing the understanding of the informal city, rethinking the former physical limitations of contemporary architecture,
and shifting the emphasis from form-driven to purpose-oriented social architecture.

one of their most recent proposals is an urban remediation and civic infrastructure hub located in grotão the heart of the
paraisópolis favela of são paulo, brazil. the challenging topography and informal settlements are transformed into a productive zone and
dynamic public space through social design – a process of analyzing the local effects of rapid growth and improving marginalized settlements
through social structures.the project is a multifunctional public building which won the holmium gold award latin america last year,
which will help fund and build the project.

the lower zone contains the fábrica da música, which stacks diverse programs to maximize the site’s potential. 
these include public transportation, sports facilities and the music school, which provides practice and rehearsal spaces, studios,
a performance hall, and auxiliary classrooms. this is a vital catalyst in the area, expanding music and cultural programs into the favela while
forming a new network that serves the youth from all levels of society. the upper level will host new replacement housing for those
displaced from the high-risk areas. commercial spaces are introduced on the first floor as an economic vehicle that activates the street space and
stimulates the micro-economy of the urban agriculture on site.

the project proposes that architects eschew their conventional role in traditional hierarchies to serve as an enabling connection between the
opposing forces of top-down planning and bottom-up initiatives. by creating common ground for these two forces, areas can eliminate divisiveness
and generate productive interactions. the priority becomes equipping this peripheral neighborhood with infrastructure, water, sewage networks,
lighting and services in addition to social infrastructure in the areas of education, safety, culture, public space, and sports. 
the new urban model aims to translate a society’s need for equal access to housing, employment, technology, services, education,
and resources – fundamental rights for all city dwellers – into spatial solutions.

the new terrace system combines necessary physical infrastructure with social infrastructure, providing space for flexible and adaptable programs.
they also make important connections to the surrounding neighborhood via existing pathways that have been disconnected.
minimum of construction is used for maximum output concerning the practical needs of safety and the desires of public space and social systems.

the ramp system moves through the site creating public accessibility from the top to bottom and throughout the space and building.
it develops a new public circulation system in an area known for challenging and dangerous topography.

the urban agriculture helps transform the space from an empty void to a productive landscape.
not only does this program provide food production on a small scale, but it also provides the community with the knowledge and
an ability to implement this system in other areas.

the wetland system provides a passive filtration system for water re-use on-site. the water can be re-used for gray water applications and
irrigation for the urban agriculture. the area acts as a catalyst to transform water, once seen as destructive force, into a productive element.
the field serves as an area for sports as well as a stage for outdoor performances. it also provides space for vendors to sell produce from the urban agriculture,
connecting many of the different pieces of the project into an activated platform.

the fábrica de música serves as a music and performing arts school. it accommodates classes, rehearsals and full performances.
the building itself is a spark for positive change and a hub/node of innovative and cost-efficient technologies.
it’s as a prototype that can be adapted to other high-risk sites as well as other areas of the city.


landscape and urban agriculture diagram

the school and landscape work as one building. the connection bridges provide access from site to the structure,
forming a comprehensive circulation path that allows the public to enter at all floors in the institution and throughout the location.
the elevator also acts as a public shaft enabling areas of ingress to all levels in the building and terraces.


terrace circulation

access to the site is provided by two roads, one at the top of the slope and the other at the bottom.
the lower street adjacent to the building contains a bus stop and
turnaround. public circulation is then able to continue up the hill
via the public elevator and bridge connections.

building systems
1. natural ventilation chimney
combination of stack, solar and wind supported ventilated system
2. hybrid photovoltaic panels
electricity during the day
IR-Emission of water during the night
3. air conditioner
4. shading
protects against solar exposure along the east and west facade
5. slab cooling
tempering the concrete structure with embedded hydronic piping
6. hybrid ventilation
natural ventilation in should seasons AC operation in humid season
7. cross ventilation
wind from south direction provides fresh air, warm winds coming from north
direction are blocked by the hill
cooling water cycle
8. heat rejection from air conditioner
9. heat sink during the day
10. heat emission during night by lunar collector on roof
11. chilled water to air conditioner


water model
1. runoff cascades over permeable surfaces,
absorbing excess stormwater and increasing water oxygen levels
2. site contours direct the water inward to minimize off-site discharge
3. runoff is collected into terraced wetland water gardens to trap contaminants and
particulars. the system is a natural filter that enhances air quality, lowers ambient temperatures by evapotranspiration, and introduces habitat niches that attract foraging birds
4. treated overflow from the wetlands is collected into an underground cistern for storage and laster reuse
5. stored water is treated to local quality standards with rapid sand filtration and pumped to elevated tanks for reuse
6. water is lifted during dry periods to provide irrigation in planted areas
7. treated water is available for non-potable uses, such as toilet flushing
8. minimal stormwater is discharged to the public swear system
