Una planta incineradora de residus sòlids urbans és bàsicament una fosa o contenidor amb una àrea de descàrrega, un pont-grua que eleva les restes fins els forns i una sèrie d'elements que permeten extreure energia del procés en forma d'aigua calenta i electricitat. Es planteja, doncs, una distinció entre la part “mecànica” del procés i la “tècnica” de transformació, que treballa amb elements manufacturats –tubs, conductes, generadors, filtres... – dissenyats com un conjunt des de l'enginyeria. En conseqüència, es projecta la primera com una arquitectura de grans caixes cúbiques, i simplement s'ordena i exterioritza el potencial expressiu de la segona. Els materials utilitzats per donar textura als diferents volums cúbics són bàsicament el formigó in situ, els prefabricats de formigó en placa i la planxa de ferro galvanitzat col·locada horizontalment en l'interior del bloc de formigó vist.

Ajuntament i Govern espanyol financen un servei, preceptiu d’ençà del 1993, per a la recollida selectiva de residus, completat per una cotxera de l’empresa Musersa. En el no man’s land industrial, el projecte adopta una actitud radical i estricta: la topografia del solar i la diferència entre servei exterior i logística interna propicien la inserció d’un cos únic, vestit de planxa galvanitzada, que inclou la cotxera i els serveis administratius. Al davant, les andanes de classificació i llur zona de maniobra; a dins, el pati de maniobra dels vehicles. La pulcra construcció de les lluernes ortogonals i la cal·ligrafia de les trobades de planxa, portals, gàrgoles... són el llenguatge contingut d’un equipament econòmic que busca en la funció i en la construcció les regles per a un paisatge industrial possible.

The Botanical Institute building – a centre dependent on the Superior Council of Scientific Research – is located at the highest point of the Barcelona Botanical Garden on the side of the Montjuic mountain together with the Olympic Ring. The building faces the north-east wing of the garden, the area dedicated to the phytoepisodes of the Western Mediterranean and North Africa, with views over the city of Barcelona. It is structured as a horizontal line that intersects the natural sloping terrain like a hinge between two topographic elevations. In this way, the section allows the different programs to be organizsd with independent access from the back road and from the network of paths in the garden. The Botanical Institute is divided into three different levels according to its program: – A first underground level located in the large concrete vessel that forms the foundations and that contains, with specific air conditioning, the plant deposits, books, the large herbarium, as well as the installations and the small work area both illuminated and ventilated through patios. This plant acts as a structural counterweight to the constructive mechanism of the upper plants; a set of reinforced concrete screens, walls, girders that organise the program and support the intermediate level at the level of the garden and from which the upper floor is suspended at the level of the access platform and rear parking lot. – The multipurpose room and the Salvador Museum, the exhibition area and the cafeteria-restaurant are on the intermediate level, connected to the Botanic Garden’s path network. All of them have access to the garden. – The restricted area intended for scientists; the library, research areas and laboratories and the administration area are on the upper level. The six-metre corridors adapt to the different structural and lighting requests, making up a continuum in which the gusts become more powerful as the topographic fall of the land becomes more pronounced. The construction uses the same materials already present in the construction of the garden; exposed concrete and Corten steel.

"Street Cleaning Services Facilities" and "Primavera District Gardens": a building under a green space. The two-hectare land where the two facilities were built is located between the residential fabric of the "Poble Sec" neighbourhood and the northern slope of Montjuïc Park and had a very rough topography and a steep gradient. Much of the plot, owned by the municipality, was covered by dilapidated buildings hidden by spontaneous vegetation. Starting from the existing topography and the platform created by the roof of the transfer centre, "Parks and Gardens" designed a new green area, with infrastructure and urban garden facilities in harmony with the façade of the new building, guaranteeing at the same time the continuity with the rest of the green space since one of the most important challenges was solving the connection for pedestrians. The development of this route required a major adaptation of the topography with a considerable earth movement, generating a system of terraces and slopes, which are supported with the help of several gabion walls. The result is practically vertical gardens, oriented towards the houses located in the lower streets, which form a new green curtain in the neighbourhood. These gardens act as a transition between the "Poble Sec" neighbourhood and the leafiest and wildest green of the Montjuïc mountain. On the terrace located in the lower area of the park, on the roof of the "Street Cleaning Services Facilities", there is a playground for children. The "Street Cleaning Services Facilities”, a 4,262m2 building under the park that is integrated into the territory, is developed on two floors and has a 90-metres-long façade. It was the implementation of an urban improvement plan that allowed this new equipment to be installed on the ground, intended for the transfer centre of road cleaning waste from "Poble Sec" and "Ciutat Vella". The commission for the building posed a complex program of requirements: a specific gauge, the imperative not to incorporate zenithal lighting, and a single façade to the north that had to solve the lighting and ventilation needs of a very diverse interior program (staff and truck access, offices, truck area, classrooms, changing rooms, ET, facilities...). A double skin system with prefabricated concrete perforated panels was sought, able to adapt to all the requirements of the façade: a simple system for a complex program. With this system and the placement of accesses for trucks and personnel at the ends of the building, we have been able to transform a dark and hostile place into a street illuminated at night and an image not so much of a building but of a garden wall, by means of a geometric game of lights and shadows. The building itself is a powerful structure that supports the loads of the park and that inside houses the changing rooms and services of the workers, an information centre for residents, the offices of the centre and spaces for the maintenance and washing of vehicles. It also incorporates three watertight containers for the compaction of garbage, which are removed every day, and is equipped with an innovative filtering system for suspended solids. The phreatic water used in the building, both to fill the tankers and for cleaning, comes from the Liceu Theatre catchment well. The new gardens are enjoyed by both local people and pedestrians coming and going from Montjuïc Park. The old sidewalks, dirty and broken, have been transformed into pleasant paths. The apple tree, which used to impress us with its wild and impenetrable state, has been transformed into a new and well-used green space that has given rise to a new "garden-wall-façade" that gives livelihood to the neighbourhood.

Ens demanen de restaurar la torre d’arribada del camp de regates de l’estany de Banyoles, que nosaltres mateixos vam fer el 2004. La manca de manteniment, les inoportunes actuacions i l’inexorable pas del temps hi han deixat la seva empremta. Després de gairebé deu anys sense cap manteniment, la brigada municipal va aplicar una pintura de color vermell que en va canviar l’aspecte, però, per sort, una subvenció del Consejo de Deportes ens dona una nova oportunitat. Fem un plantejament que, malgrat l’aparent modernitat, és ancestral en altres països: carbonitzem la fusta! Aquest tractament consisteix senzillament a protegir la fusta amb una pel·lícula de carbó. Aquest carbó superficial li dona un aspecte noble, protegeix la fusta dels raigs ultraviolats i espanta els xilòfags. Per aconseguir-ho, es tracta de cremar la fusta de forma controlada, raspallar-la i, finalment, aplicar-hi un tractament a base d’olis naturals per fixar millor aquesta pel·lícula de carbó.

El projecte consisteix en un recorregut, les indicacions i un mirador a l'entorn de la Torre Desvern, un indret d’alt valor històric i natural on es pretén reconèixer i promoure la seva riquesa patrimonial. El cercle defineix els elements com a punts en l'espai obert. Primer, el rètol de benvinguda, on comença la caminada; llavors, les lluminàries fins a l'antiga Torre Desvern, on les senyalitzacions distribueixen el visitant, i, finalment, la fita del mirador. El mirador s’alça entre ginestes i llentiscles salvatges, deixant corriols per accedir-hi i iniciar des d'aquí l'ascens per una escala de cargol. Les estries de fusta marquen un ritme vertical i les escletxes deixen entreveure cel i bosc, però de forma parcial, encapsulant l'horitzó, filtrant les textures i marcant ombres als esglaons d'acer galvanitzat. A dalt, una petita plataforma s'obre per culminar amb una extensa visual al massís de les Gavarres i la plana del riu Ter. Un mirador on gaudir del paisatge des d'un balcó privilegiat.
