Industrial complex made up of several buildings from different periods. The oldest one is the paper mill, but it has undergone many modifications. It consists of two floors and the north and south façades have been covered by other constructions. Inside, the staircase that leads from the ground floor to the upper floor is made of stone and the steps have the right half at a different height from the left, alternating one step with the other. The upper floor is a large room with a ceiling of beams and wooden crossbars and iron columns; large windows provide the room with light. There is a residential building attached to the mill.
The main building consists of three large naves of great length, and the central one wider and higher than the lateral ones. The roof is double-sided, with the ridge parallel to the main façade, and the iron truss structure. The façade is of exposed brick and is divided into three floors. There is a large number of windows arranged regularly; those on the ground floor and first floor are very elongated and those in the attic square, but all are low arched with a brick moulding at the top. Separating the different levels there is a fine molding decorated with a serration. There are two forward bodies, one on the right with a flat roof and the other, in a more central position, with a double-sided roof. In this last body, the windows break the horizontal composition and are arranged diagonally following the staircase inside. The interior has cast iron columns and the ceiling is Catalan vaulted with iron braces.
A metal bridge connects the mill building with the main one.
The chimney, located next to the steam engine room, is also preserved.
There is an isolated building, in the modernist style, which was probably built when Tecla Sala acquired the factory and, perhaps, was his residence. On the main façade there are two bodies and one of them is higher and more advanced than the other. The lintel and jambs of the openings are framed by floral reliefs, as is the case under the sill. The crowning, which is stepped, is decorated with a woman's head with her hair wrapped in flowers. Under the cornice, between the corbels that have a stepped shape, there is a strip decorated with sgraffitos and there are also the vents covered with openwork reliefs. The glasses on the top are acid etched.
In 1821, the use of L'Hospitalet's canals and streams as an energy source began. The first was the Canal de la Infanta flour mill, which was fully operational in 1824, and in 1856 Antoni Ferrer's paper mill was installed in Torrent Gornal.
In 1872, the Basté family acquired this mill and the adjacent plot to build a factory dedicated to yarn and fabrics. When the spinning mill was built and started working in 1899, the old paper building was respected. In 1913, Mrs. Tecla Sala bought the factory.
In 1937, with the agricultural and industrial collectivisations, it worked as a Maternity Home until it was returned to its owners in 1939.
In 1982, the City Council bought the building and rehabilitated it as a cultural centre.
