64 kilómetros begins with the material history of a plywood panel. According to the estimates developed for the project, the production of thirty panels of 2.5 x 1.22 x 0.025 metres corresponds approximately to the felling of seven adult poplar trees within the active forestry landscape of La Rioja.

From the plantations along the river, in places such as Torremontalbo, the trunk enters a precise and repeated route. It is cleaned, transported to the timber plant in Baños de Río Tobía, unrolled and transformed into an industrial product. Alongside this process, a secondary material landscape appears: leaves, branches, displaced earth, bark, sawdust, wood chips, vehicles, machines and temporary storage areas.

The project deliberately follows that same route, but shifts its logic. Instead of treating the by-products of the chain as waste, it incorporates them into the architectural composition. The pavilion is built not only from the final plywood panel, but also from the residue, traces and intermediate states generated by the transformation of the tree.

Installed in the Revellín car park in Logroño, the work reads the site as an available urban void between the city and the fluvial landscape of the Ebro. The pavilion becomes a temporary threshold where productive territory, transported matter and public space meet before the materials return to the local productive cycle.
