The lighting proposal relies on a recovery of space through the valorization of time and its wear and tear. General Prim 30 is a palace built in the early 19th century in Mexico City, whose deterioration is due to various geographic, political and social circumstances. To emphasize the quality of deterioration is to give value to the hidden witnesses of the architecture, the materials, the colors that speak as echoes of times reviving an era. We tried to break the visual symmetry proposing locations of accents that did not have concordance to the architectural symmetry. An extrinsic system was created with an incidence of less than 10% to be able to adapt parallel to the design and versatility of contemporary use of space by giving an indirect general light.
