In this first stage, the catalogue focuses on the modern and contemporary architecture designed and built between 1832 –year of construction of the first industrial chimney in Barcelona that we establish as the beginning of modernity– until today.

The project is born to make the architecture more accessible both to professionals and to the citizens through a website that is going to be updated and extended. Contemporary works of greater general interest will be incorporated, always with a necessary historical perspective, while gradually adding works from our past, with the ambitious objective of understanding a greater documented period.

The collection feeds from multiple sources, mainly from the generosity of architectural and photographic studios, as well as the large amount of excellent historical and reference editorial projects, such as architectural guides, magazines, monographs and other publications. It also takes into consideration all the reference sources from the various branches and associated entities with the COAC and other collaborating entities related to the architectural and design fields, in its maximum spectrum.

Special mention should be made of the incorporation of vast documentation from the COAC Historical Archive which, thanks to its documental richness, provides a large amount of valuable –and in some cases unpublished– graphic documentation.

The rigour and criteria for selection of the works has been stablished by a Documental Commission, formed by the COAC’s Culture Spokesperson, the director of the COAC Historical Archive, the directors of the COAC Digital Archive, and professionals and other external experts from all the territorial sections that look after to offer a transversal view of the current and past architectural landscape around the territory.

The determination of this project is to become the largest digital collection about Catalan architecture; a key tool of exemplar information and documentation about architecture, which turns into a local and international referent, for the way to explain and show the architectural heritage of a territory.

The project outline, very generous and permissive, is interpreted in this case from a desire for a very strict correspondence between each of the parts of the house and its own structural and volumetric solution, so that the articulation between the different bodies is forced upon themselves. The result is a combination of volumes and openings that form a series of tense rhythms where no element is repeated. Sostres revitalises several compositional guidelines from the modern movement: the location of the entire program on the first floor refers to Le Corbusier, while the strict equation of use-form-structure comes from the more rigid principles of the Bauhaus. Despite everything, the result is not a mere exercise of historicism: by interpreting ideas and procedures, and not stereotyped forms, Sostres manages to regenerate the vitality of the house as a complex system of rooms, where the blown volume of the living room being ends up playing a predominant role.

Isolated single-family home, located in the Ciudad Diagonal urbanisation, very close to Moratiel House. It is developed on two floors and four corridors that help to keep the program in the same area. The structure of load-bearing walls is what determines the volumetric development of the building, since it allows generating setbacks and establishing a game with the depth of the façades through the extension of the walls. The most important action is the extension of the living room, which, because it is cantilevered, requires two complementary metal pillars. Right next to this volume is the dining room terrace, which appears as a large void made in the main volume. Another element worth highlighting is the glass box that works as an access and is located under the overhang of the living room. The composition of the building is completely cubic, with slight slopes on the roofs that appear in the upper profile. The finish is white stoneware, while some of the carpentry is black and others white. Following the same criteria as in the Torredembarra houses, Sostres has completely separated the two types of circulation, leaving the pedestrian access in front and the road access behind the house. Currently, the perimeter fence that encloses the plot has been modified, making it difficult to see the house.
