This nucleus is made up of six single family homes on each floor and designed by Marcello Nizzoli and Gian Mario Oliveri between 1948 and 1952. Like the houses for large families, these buildings provide access to the living room-dining and study area to the south (together with the children’s bedroom) whilst the bathroom and master bedroom are situated to the north. The exteriors alternate painted plasterwork and stone covered perimeter walls. As in the other buildings designed by Nizzoli and Oliveri, some elements such as the projecting roofs, handrails and external stairs confer special and “modern” features on these apparently simple buildings from a compositional point of view.
