Ciudad Roca Negra is an architectural and urban equipment project that challenges common design methods since it involves the participation of specific organized social groups. This participation, hand on hand with architects, results in new democratic and participatory forms of methods to urban planning.
In May 2009 we were called by members of the M.T.D. (Unemployed Workers Movement) of the Municipality of Lanus Municipality in the Buenos Aires, to develop a project for the Roca Negra property, a former factory occupied by this organization. The primary economic back – up for the construction of the project is the concrete masonry factory located in Ciudad Roca Negra which supplies concrete blocks for certain parts of the design. Moreover, educational cultural, recreational and sport activities take place in Ciudad Roca Negra.
Throughout more than three years we have been developing a project that goes through different stages to generate new social proposals and design alternatives. One of the distinctive characteristics of the movement is that it is organized without hierarchies, where the democratic exercise for the decision making is made in an assembly. Thus, the first instances consisted on “participatory project assemblies”, referring to an organization of members who use parliamentary procedures for decision making. Through these “project assemblies” it was sought to reach a general plan in which the architects and the community could agree on. The traditional role of the architect as a form provider and project proposer was put aside, instruments of visualization were developed and decision making assemblies were held, generating the general framework where debate practices for project proposals could emerge, being agreed on in a collective manner.
In this suburban context where what exists are immense extensions of housing, precarious and not, and of functioning industries or abandoned after the liberal policies of the 90`s, what is lacking are the conditions that make a city the place where the strangers tend to meet, where the social exchange occur in a public and productive manner. The decision of the social movement for constructing in Roca Negra community equipment instead of housing implies focusing in what is public; ultimately in what provides good conditions for urbanity. Doing this through self-managed ways, overlapped to the traditional logics of the state, implies to develop a high level of participation and organization from the actors involved. This network of actors is dynamic and varies according to political circumstances and local energies for work. The interdependence between programs, the long lasting decision making and scarcity of resources, among other things, make this self-managed processes to last long periods of time and intermittent actions, mixing moments of great productivity and enthusiasm with others where the machinery is blocked paralyzing actions.
Architecture as a tool of transformation can provide a specific knowledge and at the same time mediate the construction of conditions that make possible this transformation.

Ariel Jacubovich´s Architectural Office has been developing and self-managing projects for public space interventions with the working efforts of architects, students, social organizations and welfare groups,in the Conurbano of Buenos Aires for several years.
In 2013, these interests developed into the Colectivo de Arquitectura Pública Asamblearia, C.A.P.A. In this way, the new projects and urban actions try to review the role of the architect andarchitecturein participative forms with its main attentionon the cultural value of collective space.
These projects are researched and developed with C.A.P.A. as a mediator between different groups, universities and in some case the government, taking into consideration local possibilities and cultural conditions.
Actually, we are developing some projects in different subjects that involvelabourcooperatives, State programme, gremial association and cultural organizationin the city of Buenos Aires.
