In the northwest area of Sant Boi there is a green space that creates a funnel-shaped void, closed at the wide end by the rear façades of some buildings. The plot offers the possibility to create a backdrop that does not exist now. The new building is generated with a uniform plan made up of few lines, related to the important scale imposed by the exterior space. The programme suggests the arrangement of three closed buildings within a single enclosure: a residence, a cultural and social building and a sports building. The three parts of the programme are contained in a single enclosure, forming three juxtaposed bodies, and the façade acts as a unifying element. Thus, each part of the programme can be developed independently, once the relationships between the elements have been established. The result is a container of large dimensions, uniform and linked to the scale and the urban requirements of the location.

The floodable ford is part of a strategy for environmental recovery and promotion of social use in the area of the Llobregat River. This is integrated into the existing network of river paths and strengthens the connection between the two banks of the river, covering a connectivity deficit between the neighbouring municipalities of Sant Joan Despí and Sant Boi de Llobregat. The ford saves 30 metres in length at the crossing point. It consists of the succession of a series of concrete boxes in situ. The width of the passable platform is sufficient for the crossing of pedestrians and bicycles, and at the same time it accommodates the discontinuous lateral protection elements and limits of the banks of the ford. The action has been completed with the concrete path that saves the unevenness on both sides, adapting to the existing slopes until reaching the gravel paths and with the restoration and revegetation of the sides of the area affected by the works.

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 programme, comprised of protected, affordable and mixed social housing, requires the available volume to be almost completely filled. This limitation alonside the self-imposed requirements of efficiency and simplicity, poses a challenge in building a project with some added value. An investigation was carried out to find the hidden potential of a proposal that is pragmatic but also sensitive to subtle external stimuli. A 12 housing units floor plan is drawn that uses up the limited connection space by introducing a trough-vestibule with a single central core containing two intertwined stairs, two elevators and two installation cores. This leaves us with a single through-vestibule and a single service core on the ground floor affecting the clarity of the retail space and the underground parking garage. With regard to the dwellings, the living rooms and bedrooms are outward-facing, while the kitchens, bathrooms and hallways face the walkways shared by each group of three neighbours. From this layout, which solidifies the available volume, subtraction operations are performed that wittle away the volume to generate a new morphology with generous collective and individual terraces, facilitating cross ventilation and diagonal views by lightening the original density and orienting the building towards its most attractive landscapes. The exterior facades are repetitive, clad in industrial ventilated panels. They feature large groupes of windows with an accentuated horizontal dimension that simplify the appearence of the building (fortunately surrounded by públic space) and give it a certain monumental quality. Colour is an important ingredient of this distinctive silhouette, with a playful range of green hues that respond to the possibilities of the surroundings. The facades of the patios and walkways are in very bright and luminous colours, combining two similar hues to create a vibrancy that enhances their joyfulness. The materials employed give it an almmost picturesque quality though the use of lattice, tiles and floorings that create a herringbone patern widely seen in the Mediterranean tradition. Inside the dwellings, the joinery enhances a desired "balcony" effect that significantly expands the interior space.
