The project concer an extension building of an existin restaurante, in the historical center of Oaxaca, Mexico. The client wanted to maximize the commercial area by roofing the next courtyard, yet covered by an old metal roof. First of all we studied the terget client, who led us to go for an architectural object which comunicate robustness and simplicity. Then, another poit which defined the architectural concept was the existing enormous adobes walls, so we decided not to touch them, but to protect them by a new roof. We left the wood and metal material in their original textures, in order to play at best with the warm light of the Mexican sun.
