The villa was built in a lot between Via Sant'Imerio and Via Petrarca in Varese. Stairs lead to the first of the three main floors; the last floor is an attic.
The rooms are all different in height and width; the up-and-down passages running through the house create its functional areas and recall Casa Muggia at Barzana. For example, the dining room at the far end of the multilevel living room is raised compared to the rest of the room.
This is a new interpretation of the Raumplan concept developed by Adolf Loos; the design of the Martegani's house was also inspired by the Austrian model and its use of very simple materials, e.g., white plaster covering the reinforced concrete structure. The plaster contrasts the copper sheet roof with gutter and under-gutter, also in copper.
