Over time, the building has been remodeled several times. In 1901, the main courtyard and corridors were covered with an iron and glass translucent roof. From 1901 to 1908, it housed a major collection of works from the French Enlightenment as well as an extensive collection of fine arts. The latter eventually became part of the collection of the Academy of San Carlos. After the Mexican Revolution, it became government property, and it was remodeled to become the seat of the Secretaria de Justicia e Instrucción Pública. In 1962, architect Jorge L. Medellín and engineer Manuel M. Haro it was remodeled again, modernizing its electrical system and pipes. Since it became government property in the early 20th century, the building has housed a number of government agencies. Initially it was the home of the Secretaria de Justicia e Institución Pública. After that, it housed the Secretaría de Fomento and Secretaría de Comercio y Trabajo from 1917 to 1934, the Secretaría de la Economía in 1947, the Secretaría de Industria y Comercio from 1959 to 1961 and the Compañía Nacional de Subsistencias Populares until the early 21st century. Since 2005, it has been with the Instituto Nacional de Antropología e Historia, which uses it as its main headquarters and has restored much of its decorative work. In 1989, cracks, fissures and other damage were detected from the building's tilt towards the nearby Metro Station. Initial efforts to correct the damage were undertaken in 1990-1994. Starting in 1995, a hydraulic system to inject and extract water into and from the subsoil was developed, buried forty meters under the building. Much of the building's sinking is due to dropping water tables underneath Mexico City because of the overpumping of groundwater for drinking. The hydraulic system is designed to artificially maintain water pressure under the building to keep it from sinking. The building covers an area of 3000 m², with 60 rooms such as halls, dining rooms, kitchens etc. It has two courtyards, with a fountain in the main one. The other courtyard functioned as a stable in the 19th century. This building is similar to Tolsa's Palacio de la Mineria in that both have two facades. The main facade is on Argentina and continues around the corner onto Donceles. The main facade is split into three sections.
