The Torres Amat factory house is located in Sallent, in the industrial basin of the river Llobregat. The nave is a rectangular construction made of stone masonry three floors high, seated on the remains of a water mill that acts both foundation and basement. It is structured in three cradles, with two lines of foundry pillars, parallel to the longer facade. These lines of pillars are tied together by wooden beams on which are loaded with ceramic vaults. The last floor replaces the pillars with wooden horses that support the roof made of flat ceramic and Arabic tiles. The ship, being attached to the factory house, did not have its own ladder, so when segregating to become a library, it lacked vertical communication. On the other hand, access from the street was produced, due to the steep slope of this, from the lowest floor. These problems of accessibility and general mobility are the driving force of the project.
With the obligation to use only the first and second plants, it was decided to modify the entrance placing it in the upper part of the street, which means that the access level to the first plant was reduced considerably, which forced to create a mezzanine Between the ground floor and the first. This mezzanine floor coincided with the cradle of the nearest ship to the factory house, so it was completely remodeled to accommodate the accesses, elevator and staircase, as well as services and offices. The existing structure of the building was maintained, restoring the wooden horses and the covering of tile, protecting the deck with a sufficient fire-retardant treatment. In the rest of the structure the system of foundry pillars was maintained, supplemented with L-shaped profiles that connected them with the new jácenas that, embedded in the breasts of the vaults, presented the whole. The old wooden beams, in turn, were supplemented with a metal plate that, through asparagus, connected to the new jácena.
In order not to add useless weight to the building, a red rubber flooring was chosen and both the cabinets of the environmental conditioning and the interior enclosures were made in waterproof board, painting them in red color. The fact that it was designed to accommodate the most distant of the main façade to access and services, gives to the work rooms a dimension not too wide that allows a generally acceptable illumination. The new entrance was also treated by a large metal cube that housed the double door and was embedded in the wall. The artificial lighting was placed on metal supports hung from the ceilings that supported the electrical installation.
