The House on Via della Caupona was installed in an older building, dated to c. 250 AD. The house was built in vittatum in the years c. 270-275 AD. In front of the entrance is a porch consisting of two lateral walls with benches on the inside, between which is a floor of bipedales. The house has a very large vestibule (A). On the floor is a geometric black-and-white mosaic with a few red tesserae. The walls were painted. In the left wall are two semicircular niches that were lined with marble. They do not seem to have been fountains.

At the end of the vestibule is room B, slightly raised, that was reached along two marble treads. It has a marble threshold, flanked by brick piers. On the floor is polychrome opus sectile. The walls were lined with marble.

In room C is a black-and-white mosaic with a few coloured tesserae. It has geometric and vegetative motifs. The walls were painted. Room D has polychrome opus sectile on the floor. The walls were decorated with marble.

Corridor E has a floor of bipedales. It leads to another small vestibule (F).

The building is also known as Domus del Garofano, House of the Carnation, apparently recognized on the floor of room C.
