The main features of Casa Cherchi are its three floors, built entirely of raw mud bricks (ladiri), with walls between 50 and 60 centimeters thick.
The main façade, in Art Nouveau style, features a top cornice made of stone slabs, adorned with a central statue, large decorative vases on each side, and ornamental stone spheres.
Two central balconies with wrought iron railings completed the first and second floors. On the ground floor, a wide staircase marked the main entrance until 1950.
To this day, many of the rooms in Casa Cherchi still preserve their original floors and frescoed ceiling decorations.
In 1950, the building underwent substantial changes made by the owners, Felice and Narciso Cherchi, who divided the house into two separate units.
