The original layout of the building dates back to the Republican age and has changed significantly after the earthquake of 62 AD. Renovation works were still in progress at the time of the eruption in 79 AD as evidenced by the presence of unpainted plaster on the walls of various rooms. In two of them the wall decoration was already completed with its characteristic red colour that named the house.
The lararium, which is a small aedicula, is found in the atrium, intended for domestic worship, where six bronze statues of protective deities of the house were found.

Date of excavation: 1832; 1882.
