The Final Grade Project objective is to develop a technical project for the restoration of the "Alvear`s Palace house" to keep his use as single family home. I hace chosen a PFC conducting to a technical project because it allows to implement almost all the knowledge acquired throughout my degree, and at the same time extending them to adapt this knowledge to the typical construction of my birthplace, Cantabria. I have selected this type of construction because I would like to continue my work experience in this province, and in particular I would like to devote to building restoration, so I think that the realization of this work will help me to learn many technical aspects of the construction, operation of the companies involved and current legislation in this province. The building is situated in San Pantaleon de Aras, in the region of Trasmiera, and the construction is a typical “montañesa” house of XVI-XVII century. It consists of ground floor, first floor and an attic. The building is in an advanced state of degradation due to age as they hardly have carried out maintenance work on it since its construction. The main objectives of the project are surveying, as there is no graphic documentation of it, executing a study of damages in order to propose intervention measures, and finally a rehabilitation proposal to the adequacy of building regulations, current redistribution of interior space and the adequacy of facilities. I have attempted to keep maximum aesthetics and techniques of construction and building materials typical from this houses, but at the same time adapting the building to current standards of design and comfort. This will try to keep up the original materials are suitable thermal and acoustic enclosures by adding thermal insulation and replacing the joinery, creating new openings in the facades to give light and redistributed within the interior space in new rooms with their respective facilities
