After diagnose the building, with hisIDSy investigation, level measurements, and several studies we conclude that the most important reasons of deterioration were water filtration and humidity. The intention of returning the original conditions to the building was the answer to the problem detected. The resault was the demolition of the added constructions that deform its original volumetry. Morover, we proposed an integral treatment of the enfoldment, changing the deteriorated roof with a new cooper cover. Team: A. J. Maletti, F. Zanel, L. Maletti, W. Robaina.
