Resumen:
Actions in patrimony should be the result of the respect to our heritage and an exhaustive knowledge of the buildings from their initial conception, and should be obtained prior to any intervention, to assess the physical reality and the evolution of the historical building over the time. A research of the evolving needs and the
consequent adaptation of the building to them is made. Educational buildings destined to technical instruction have undergone an evolution on their architectural determinant factors intrinsically linked to the own evolution of
higher education. Particularities of the Civil Engineering Degree have been studied from its early stages through the different locations until the construction of the former headquarters of Cerrillo de San Blas. The knowledge of the fact and the physical whereabouts is found by first considering the approach on a city scale, and then moving on to the nearer environment, until the building is understood.
