El projecte adopta una configuració distributiva que vol respectar l’equivalència entre el passadís, la sala d’espera, l’aula o la consulta, que són els elements propis d’un centre d’assistència primària. En una planta baixa rectangular es disposen quatre corredors longitudinals que divideixen l’àrea en cinc crugies iguals. Els elements del programa s’insereixen dins les bandes, tot evitant la continuïtat dels passadissos i afavorint la flexibilitat de les circulacions. Els patis interiors esdevenen els elements clau que atorguen identitat a cada àmbit, i queden reflectits a la planta coberta com les úniques peces fermes de tota la distribució.

We recover a typology which is not very usual in the Eixample, Antonio Bonet's "Mediterraneo" block, a hybrid that did not seek so much to break with Cerdà's rules, but to explore the true potential of those ordinances that were never approved, which allowed accidents to be approved as a regular and not exceptional component of the Eixample. The project widens the sidewalks, moving the pedestrian away from the road traffic to the point of visually and physically connecting Londres Street with a park inside the block, and recovers an idea of a permeable block that is in the origin of the Eixample. Londres Streets extends the 20 metres with a succession of parallel spaces. We divide the building into narrow, parallel and staggered volumes from north to south, allowing the sun to reach both the homes and the children's classrooms, avoiding the compactness and ventilation courtyards typical of the Eixample, and we achieve that two different programs (school and housing) coexist and dialogue. A passage that decongests the sidewalks of parents and students appears between these two programs. There is an alternation of full and empty spaces, of light and building, creating visual relationships and transversal connections between the street and the interior of the block. Therefore, the project proposes to requalify the accesses, circulations and open spaces, both in the school and in the homes: the roofs are playgrounds, the walkways are places of relationship and exchange. The housing block is organised in a corridor of 7.5 metres deep, obtaining 45 pass-through homes of 45 m2 with natural cross ventilation and sun throughout the home thanks to the shallow depth in which they are developed.

The Sant Gregori School in Barcelona was built in 1972 in Collserola. The original project was laid out on terraces of the land, staggering the slabs. The integration of its section is attractive, as well as the fluidity of its interior, but it currently has serious accessibility and evacuation difficulties, a lack of facilities suitable to current standards and, in addition, it is a school that lacks pre-school education (3 to 6 years). Therefore, the assignment focused on the reform, improvement and expansion of the facilities of the current teaching centre, and on moving the children's classrooms, currently in Arimón Street. The expansion foresees the construction of an underground car park, 6 classrooms for the pre-school cycle (3 to 6 years old), 6 additional primary classrooms and a music school that will equip the centre with a new multipurpose room (gymnastics-shows) with a capacity of up to 300 people. The starting urban planning requirements were: - Set back the building (to not create a façade on Carles Riba Street). - Unitary intervention, not fragmented. - Occupy the natural space of the rest of the plot as little as possible. -To not extend to the high elevations of the plot. In addition, we add that the intervention should be minimal in appearance; it would be an operation of occupying voids, emptying and filling again, replacing floors in poor condition, creating multipurpose spaces, using the roofs as playing areas that allow children to be separated by ages. The school had a natural outdoor reception area with 3 pine trees that we set out to preserve and enhance. Around this courtyard and replacing the first terrace on which the school is located, we have built a new semi-underground administration (control and reception) which allows connecting the old building from street level with a lift. To the east, a multipurpose room (sports and entertainment) with a cover that is a basketball court. This layout is closed to the west with a grandstand-staircase that creates an agora, an outdoor public space covered by the three pines, which connects to the stage of the multipurpose room thanks to a large sliding door. Therefore, the spaces are linked, and the stage can pivot and serve inside or outside the agora. The result is a new welcoming space where parents or children can wait, play or perform shows. It is a space that is not bounded by walls but continues towards the interior of the building, giving it greater depth especially in the afternoon with the illuminated administration. The rest of the volumes are placed to the west, restoring the profile of the excavated mountain, receding and staggered, creating playing terraces and connecting to the old school to facilitate its evacuation. Children's classrooms on the ground floor, primary school on the first floor and music school on floors 2 and 3, a dislocated volume of two floors that is placed over the kindergarten and primary classrooms, covered in anthracite Zinc. At first floor level, the new roofs are finished with green Composan, connecting all the spaces longitudinally with great fluidity. The building has obtained an "A" energy rating. The entire face exposed to the south is protected by flights or by a lattice of pine wood that protects the classrooms from direct sunlight. In the same way, the basketball court above the multipurpose room is surrounded by Rivisa galvanised mesh through which climbing plants will climb.

For the first time in Barcelona, two usually separate programs are combined in the same building: sheltered rental housing with temporary accommodation equipment for the inclusion of the most vulnerable groups. The design of the set responds to three basic criteria: 1. Urban responsibility: we generate a public space and equip the ground floor with collective services. We organise the program in three vertical blocks, generating a public space as mentioned but with an interior street that separates and at the same time connects the accommodation with the homes and organises the accesses and communications allowing good cross ventilation throughout the whole. 2. Social responsibility: we understand the inclusion and accessibility of marginalised people in the broadest sense from the program. We match or compensate the conditions of the different parts of the program and dignify the accommodations without increasing the cost. It will be possible to reuse the building of temporary accommodation with another use and we obtain a balance between the parts of the program, because all the houses have the same qualities, there are no differences in orientation or sunshine. 3. Energy responsibility: we respond to the site and the program with a passive environmental attitude that reduces energy demand: good ventilation and good solar capture, saving energy. We get 100% of homes with sunlight. This makes it possible to activate the passive solar energy harvesting device of winter gardens, which cover 23% of the heating demand in winter. In summer, nighttime cross-ventilation of the conservatory and its daytime solar protection with shutters covers 43% of the cooling demand. This is complemented by high-efficiency systems such as aerothermia and a heat recovery system for double-flow ventilation, thus achieving an A energy certification for the finished building.
