The complex constitutes an austere fabric of industrial constructions where Puig i Cadafalch aims to demonstrate the validity of the construction procedures of the past for modern needs and programs. The large cellar uses half-point arches made of six courses of brick supporting recessed vaults that reach the façade, combined with slightly pointed arches. The pavilion of expeditions chooses to use a large, inverted catenary made exclusively of brick, supported by crossbeams also made of brick and with a stone enclosure. Puig i Cadafalch uses the shapes given by the support elements to compose the façades, both frontal and lateral, in a way that expresses this support, although it also introduces other strictly ornamental elements, such as the stepped profiles of the openings, the lattices of brick, the series of buttresses or the stone pinnacles.

The farmhouse and the Codorniu cellars were completely renovated at the beginning of the 20th century by Josep Puig i Cadafalch following the modernist aesthetic. Puig built the press porch, the large cellar and the expedition pavilion (1904) and redid the farmhouse or Can Codorniu Tower (1906).

The Codorniu house is an isolated house, built on the old farmhouse, and surrounded by gardens that separate it from the industrial buildings. It is of a neo-medievalist nature, with a clear desire to confer an image of prestige. It consists of a basement, ground floor, main floor and attic, with a circular tower in one corner, with a conical roof of glazed scales. It also has two small turrets attached with similar characteristics. In the attic a gallery of semi-circular arches opens. There is an inner courtyard, with columns and arches, covered with a recessed barrel vault, of printed glass. It houses rich furniture.

The press porch is a construction with a rectangular plan, formed by successive vaults of sheet tiles on half-point diaphragm arches. The façade has pointed arches and the stepped crowning. As in the rest of the buildings, the use of exposed brick, stone and green mosaic stands out.

Next to it there is the large cellar, modernly extended with new constructions by the architect Lluís Bonet i Garí. It is rectangular in plan, covered with a sheet of tile vault, supported by lattice beams or by three semi-circular arches on pillars, which support the tile toral arches of the vaults. The windows are made of lattice.

The expedition pavilion is located near the main entrance to the quarries. It is a large unit with a rectangular plan, covered with a vault of sheet tiles on parabolic toral arches with lunettes. The openings are also parabolic, and there are pinnacles between the lunettes.

The complex is completed with more recent buildings, which do not detract from the previous ones, and huge underground caves.

Can Codorniu is an old farmhouse located to the right of Anoia, which since the last quarter of the last century has been the oldest and one of the most important champagne production companies in the country. The farmhouse, traditionally dedicated to wine production, has been documented since 1551, and belonged to the Codorniu family. In the middle of the 17th century, a girl from the farm married Miquel Raventós, also from a vineyard family in the region. In 1872 Josep Raventós i Fatjó started making sparkling wines, in the style of French champagne, and in 1885 his son Manuel Raventós i Domènech founded the current company, the facilities of which were completely renovated at the beginning of the 20th century by the architect Josep Puig i Cadafalch.
