In 1974, 7 more laboratories were built, divided into four buildings. In addition, the Occupational Protection and Safety Building was also constructed, resulting in a grand total of 3000 square meters of building area. In the same year the Nuclear Magnetic Resonance Service was transferred from Rome to the Area together with the Institute of Structural Chemistry , and the area was fenced off.
In 1977-1979, on the basis of the Rebecchini-Papi Project, 9,500 sq. m. of buidling were constructed. These included the Central Building, which subsequently housed the Area Management and common services (canteen, coffee shop, library, warehouse, data processing center, and meeting rooms) and an additional 12 buildings, which were partly reserved for Institute headquarters, and partly for common scientific services, a main gatehouse and a guesthouse.

In the following years it underwent its own original process of growth with the development of operational potential of both the Institutes and the Joint Services, as well as a remarkable ability to study and intervene in territorial problems, reaching the end of the 1980s with about 350 staff units located in 25,000 square meters of building complexes. In those years, in fact, transfers of other laboratories and institutes took place: at the end of the 1970s it was the turn of the Chromatography laboratory, and soon after, in 1980, it was the turn of the Institute on Atmospheric Pollution, and in 1982 of the Institute for the Study of Phoenician and Punic Civilizations. Between 1994 and 1995, the Scientific Services were born, under the control of the Area Director, with the aim of providing equipment and laboratories common to all the institutes.

Subsequent to 2000, the last buildings were constructed and the Area took on its current appearance, with the establishment of the Institute for Environmental Geology and Geoengineering (IGAG) and that of the Institute for the Study of Italic and Ancient Mediterranean Civilizations, the relocation of the Institute for the Study of Nanostructured Materials (ISMN) in 2002, and the arrival in 2006 of the Institute for the Conservation and Enhancement of Cultural Heritage and, in 2008, the Institute for Water Research. Of more recent arrival is the newly formed Polar Science Institute. Currently in ARRM1 there are about 400 staff and 11 CNR Institutes housed in buidings covering an area of 37,000 square meters.
