At the end of July 2009 the organization of the Congress of Ciudades Creativas of Cáceres contacted us to organize a workshop on interventions in the public space with a participatory nature. In the conversations that we had with the organizing team, the initial idea changed: going from proposing a theoretical workshop to a more practical proposal of design and self-construction of portable equipment.

A multidisciplinary device

This device is built on recycled materials and structures, and its function is to host a program of parallel activities to the congress (wikiplaza, debates, theater ...) to serve as a test for the prototype, which we call Cacharro 2.0.

It is composed of second-hand transport containers, joined by a structure made of material recovered from street rails, which Public Works had replaced to fit the safety of drivers, and profiles from the dismantling of a silo in a village near Cáceres.


This structure is covered with plastic sheeting and the floor is paved with formwork board. The system is complemented with basic facilities and aims to achieve a balance between performance and ease of assembly.


The use of containers avoids the need for anchors and provides secure spaces for storage. The installation involves a certain effort: between two or three days for its assembly, depending on the size of the equipment, and a day for its disassembly and storage. This means that the optimal period of use for an installation is multi-day events, such as film festivals, music or scenic arts, neighborhood parties, thematic days, seminars, congresses, and so on. It can also be proposed as an occupation workshop, auditorium or temporary exhibition hall for neighborhoods that lack them, or as a means to revitalize underutilized or developing public spaces.


The occasion takes advantage to delve into the spirit of collaboration that we have been experiencing from the network of Arquitecturas Colectivas. We hold a series of meetings open to local groups on the possibilities of use and management of the prototype in the period after the Congress, which has the support of the city council and the candidacy for cultural capital. A team made up of members of Straddle3, Recetas Urbanas and ASILO is in charge of the design, the collection of materials and the participative construction workshop of the prototype. 


Hackitectura, ColoCo, Re-farm the City and Esto no es un Solar are incorporated into the activities held during the Congress, which consist of a Wikiplaza day, workshops (Portable Orchards, Inventing Playing), presentations and even a theater piece from Luz Mando.


The experience shows that the prototype offers good benefits and the system that the city council agreed to, allows the cacereños to plan and consider the use of the equipment with a reasonable effort and a ridiculously small economic cost.
