The Titan Cinema building is a noucentista construction from 1926, extended in 1996 to accommodate a civic centre. The new program of the library in 2004 required an increase in surface area, which was solved with the excavation of a basement and the provision of a loft. The new section of the building is complemented by the presence of interspersed courtyards, a large skylight and the widening of the façade openings. The visual connection between inside and outside and between top and bottom becomes direct and increases the clarity naturally on all floors. The screening of this new transparent component is carried out using special slats and glass, which guarantee the correct solar exposure and visual control, and become the new image of the main façade. An aedicle in the south corner creates a singular element on the other side of the rotunda tower. Most of the furniture elements and railings are prefabricated wooden beams, to achieve maximum light with the least number of supports.

The old Can Surís factory was built around 1897 and is listed in the Architectural Heritage Protection Catalogue of Cornellà de Llobregat, due to its historical and typological value. It is located in Plaça de Can Surís, s/n in Cornellà de Llobregat, next to the old road that linked the towns of Cornellà de Llobregat and Sant Joan Despí, in an area of recent urbanisation and remodelling, with the passage of the new TramBaix train. The building was unoccupied and abandoned, empty of any type of pre-existing facilities, and in a process of accelerated degradation due to lack of maintenance. The work was carried out in three phases between 2001 and 2009. The first phase included the complete refurbishment of part of the structure, the façades and the roof, and the renovation of another part of the structure, to be used as a public facility, but without a clear specific programme. This first project included new vertical communication spaces – main staircase, lifts and emergency stairs –, services and facilities for an unspecified programme, but which required a high degree of flexibility on the different floors. The second phase developed the programme of use on the ground and first floors, with the necessary interior fittings, as well as the specific fixed furniture. The project envisaged the provision of the necessary spaces to develop the programme of the new Citizen Innovation Centre for the Knowledge Society, in its sections: social dissemination-dissemination (ground floor), polytechnic learning-development (first floor) and finally digital-media realisation-production (second floor), which would be executed in the third phase. This programme called for a high degree of flexibility on the different floors in order to be able to adapt over time to the introduction of new technological developments. The access was reinforced with the construction of a double-height linear porch attached to the main façade that allows a friendlier reading of an industrial building, while serving as a filter between the activity container and the exterior access and leisure space. This steel and glass pergola contrasts with the solid brickwork and gives the building a new, more contemporary image; its placement reinforces the reading of the building and responds to the new use for which it is intended. The entrance leads to the foyer which is developed in the triple height of the building. This way, on entering, the character of the JOSEP M. JULIÀ public building is recognised and the magnitude of the three floors of the new centre can be glimpsed. The third phase of the refurbishment of the former Can Surís factory included the completion of the complete refurbishment of the second and ground floors, in terms of the interior divisions, services, finishes and all the installations necessary to use it for the extension of the Citilab-Cornellà public facilities. The project for these upper floors developed the new digital art programme in its realisation and production sections, and includes two sets of different sizes for multiple uses.

On a plot of reduced surface area, a ground floor is organized in the shape of a "U", around the preschool playground, which frees up the rest of the plot for the primary school playground. The classroom has been conceived as a volume of three floors in which the kindergarten classrooms, oriented to the south, have direct contact with their own courtyard through a porch. A south-facing corridor, protected by a latticework of ceramic pieces, gives access to the primary school classrooms which, located on the first and second floors, receive light from the north. The lattice works on several scales, from Ronda de Dalt the main façade of the school is very visible, and it integrates into the landscape of large containers of the neighbouring industrial estate, while what stands out in the middle distance is the three-dimensional geometry of the pieces. From the inside it forms a double façade that controls the light and creates an interior landscape of colours, lights and shadows, which change over time and with the movement of the observer.

Restorative and austere public spaces: that is to clean, order and repave instead of starting from scratch. Intervention is only carried out at strategic points to clean up the old fabric, particularly degraded over the years. The space flows free of obstacles and establishes the relationship between the public buildings that are concentrated here. They force us to maintain some pre-existences and we respond by projecting the space as a kind of patchwork: we keep the central part of the old garden square which gives it a certain character of a town square. We do the same with the children's leisure areas that we circle in an elliptical enclosure, and with the farmhouse, which we free from the fences and surround it with public space. The church, the town hall building and the farmhouse itself complete the patchwork.

The landscape suitability of the building derives from the spatial strategy established in the cross-section which carefully adjusts to the geomorphological characteristics of the territory taking advantage of the fact that the building is located at one of the characteristic turning points of Barcelona, when the plain changes the angle of its downward slope towards the sea. Thus, while the vessels and the bleachers belong to the topographical section of the land, the rest of the building is included in a large superimposed and almost floating roof, so that the richness of its empty interior space derives from the capture and the visibility of the landscape flows that cross it. On the first floor, everything revolves around a circulation ring that gives access to the various outbuildings and the large corner of the beam that covers the swimming pool vessels is used for the location of the remaining air conditioning machinery, included in the parallelepiped volume of the building.

In an environment of high-rise residential buildings from the 1960s, the new equipment is located occupying interstices between a school and a new social housing building. The new library is thus a ground floor and basement building with little façade. With this limited plot, we propose large interior spaces illuminated from above and a landscaped roof filled with eighty large-format cylindrical skylights, which are the natural lighting of the building and one of the formal protagonists of the equipment. The central space of the library building is the general reading room. A bright, open space full of activity. A large room characterised by its natural lighting and by the visual relationship it establishes between the upper and lower levels of the building. Externally, a porch and a glazed façade allow you to read the two programs of the building, an assembly hall and the library. A double equipment and a point of reference for the neighbourhood life.

The objective of the proposal is the identification of the main conditions for the environmental recovery of the Llobregat River, as well as the definition of the necessary actions to improve its accessibility from the different municipalities that surround it and enhance its social use to carry out leisure activities. It is about thinking about the river as a complex, which gives it a unitary landscape treatment criterion, which serves both to facilitate its future maintenance, and at the same time to understand it as a unit. The development of the proposal is based on understanding the river from two complementary points of view: - The river as a living and changing entity, full of life and a natural space with its own dynamics and functioning. - The river as a green and peri-urban leisure space, which should be a place of enjoyment for citizens, while respecting the environment in which it is located. The landscape proposal understands the river as a green space connected to the city and its surroundings.

The building is organized around a courtyard that links a sequence of intermediate spaces. On the ground floor, a portico open to the city anticipates the doorway of the building and filters the relationship between public space and the communal courtyard that acts as a small plaza for the community. Instead of entering each of the building’s hallways directly and independently from the outer façade, the four communication shafts are located in the four corners of the courtyard, so that all the inhabitants come together and meet in the courtyardplaza. On the typical floor, access to the dwellings is via the private terraces that make up the ring of outdoor spaces overlooking the courtyard. The building’s general floor plan is organized by means of a layout of communicating rooms. There are 114 spaces per floor, 543 in the building, of similar dimensions, that eliminate private and communal passageways to make full use of the surface area. The server spaces are arranged in the central ring while the rest of the rooms, of undifferentiated uses and size, approximate 13 m2, run along the façade, presenting themselves to different forms of occupation. Another terrace in the outer ring completes the spatial sequence, the row of spaces interconnected by large openings, permeable to air, sight and movement. The 85 dwellings are distributed in four groupings, with a total of 18 units per floor. Four or five homes are laid out around each nucleus, so that all typologies have cross ventilation and dual orientation. The homes consist of five or six modules, depending on whether they have two or three bedrooms. The inclusive, open-plan kitchen is located in the central room, acting as a distributor that replaces passages, while making domestic work visible and avoiding fixed gender roles. The size of the rooms, in addition to offering flexibility based on ambiguity of use and functional indeterminacy, allows an optimal structural space for the wooden structure. As this is social housing, to ensure economic viability the volume of wood required has been optimized to 0.24 m3 per square metre of built area.
