This was a small commission to design a pavilion for a construction fair in Medellín and to make the project more interest for us, we proposed to the client a series of conditions: - The project must be built with donated materials from the different participant companies and put together as a mix of a same size panels distributed all over the façades according to the sun orientation or the bioclimatic strategy. - These material must have some bioclimatic or sustainable qualities or be affordable. (Due to the amount of companies interest in participate this terms were not always completed). - The pavilion must be disassembled and donated to a low-income community or neighborhood in the city to function as a community space for all kind of events.
