Filippo Rattazzi - M.Sc. Arch. EPFL - Portfolio by Filippo Rattazzi

The following portfolio is a collection of projects carried out over the last five years. The selected works have been realized in the context of architectural studies at EPFL, during internships and independent activities.

Symbiosis, frugality and resilience: The Cubotron and its Surroundings. The project presents an alternative proposal for the future of the Cubotron, one of the oldest buildings on the UNIL-EPFL campus. Rather than demolishing it, the project proposes to renovate and extend the Cubotron to incorporate multifunctional public and academic spaces. The project aims to strengthen the links between UNIL and EPFL by creating a services hub accessible to all while rethinking the surrounding areas to encourage soft mobility and biodiversity. Avenue Forel is redeveloped to improve continuity between the two campuses and provide an attractive, sustainable living environment.

Architecture is one of the major pillars of past, present and future societies. The following project brings together the major points concerning architecture’s ability to mitigate the various problems associated with crises.

Architecture can survive the climatic and environmental crisis, and even help mitigate it.

The work is structured around three axes: the symbiosis between natural and built environments, the frugality of built environments and, finally, their resilience over time.

Starting from the three fundamental questions that Kant considered to be those of critical philosophy:

- What can I know?

- What can I hope for?

- What can I do?

The reflection takes shape and is structured around them.

Inaugurated in 1974, the Cubotron is currently occupied by EPFL’s physics faculty. The project proposes not to demolish it, contrary to the wishes of the campuses, but rather to convert it into a multifunctional hub.

All necessary public services are integrated into the “donut” on the first two floors. The following floors are dedicated to university studies, but have no fixed typology; they are designed to accommodate all the different faculties on campus.

Finally, two additional floors are added using a steel structure, requiring no modification to the existing reinforced concrete structure. For public and academic use, these additional floors house a bar-restaurant and an amphitheatre, and provide an observatory on the evolution of the campus over the coming decades.

intergénérationnel, ouvert à toutes et à tous. Finalement, le projet intègre une végétalisation continue, indigène et diversifiée, favorisant le développement des milieux dédiés à la biodiversité. La mise en œuvre de ce principe doit permettre de servir de support non seulement à l’augmentation de la biodiversité - mais aussi au bien-être des utilisateurs sur le campus. Cette solution permet en effet d’intégrer tous les services écosystémiques rendus par les arbres en ville entre autres les qualités d’ombrage, de la fraicheur pour l’amélioration du climat urbain, la mise en valeur du paysage ou le piégeage du gaz carbonique – afin de faire du futur campus UNIL-EPFL un lieu agréable et accueillant.

Cité-jardin du Bouchet: Coin-de-Terre is a renovation project for a villa listed in Geneva’s historical register. Built between 1934 and 1936, the homes in the neighborhood are protected. As a general rule, the character of the site is to be preserved, in particular the way in which the buildings are laid out, the layout of communal and private outdoor spaces and the vegetation. As far as renovation is concerned, the architecture of buildings must respect the character of the ensemble of which they form part, particularly in terms of size, volume, scale, materials and colors.

Using and reworking the 1932 plans, sections and facades, a new typology for the villa was developed. The facades were insulated without disproportionately altering the overall volume of the building. The interior was redesigned to offer more open and luminous spaces, without having to modify the original load-bearing structures, which are listed and protected as part of Geneva’s heritage.

Coliseum of Particles describes a futuristic project linked to CERN’s expansion, which involves the construction of a new particle accelerator much larger than the current one. To manage the 9 million cubic metres of excavated material, it is proposed to reuse it to build a self-sufficient circular city along the path of the accelerator. This city would incorporate essential infrastructure and housing, while aiming for maximum self-sufficiency through permaculture and local manufacturing. The project also seeks to avoid an economic decline similar to that of Detroit, in the event of a crisis in Geneva.

La molasse extraite lors de l'excavation du nouvel accélérateur de particules est directement employée pour la construction du socle technologique du LHC. S'en suit une croissance organique du bâtiment, qui grandit à la vitesse des excavations.

4 Quadrants

Avec la molasse en tant que matériau de construction primaire, il s'agit tout d'abord d'en connaître sa nature, ses propriétés pour en déduire un système constructif efficace. Un pisé composé de molasse fonctionne en compression et l'épaisseur des murs augmente drastiquement en fonction des charges. C'est pourquoi la hauteur de la construction initiale fût réduite, ainsi que le dimensionnement des porteurs revisité.

Négociation / Incorporation

The circle is subdivided into four quadrants, each representing a model of urban agriculture: incorporation, infiltration, secession and negotiation. In the north-east, Geneva adopts an incorporation model with a clear separation between agricultural and urban areas. In the south-east, Annemasse follows an infiltration model with more spontaneous urban agriculture. In the south-west, near Annecy, the secession model emerges in a sparsely populated area. In the north-west, a negotiation model applies to medium-sized municipalities. Permaculture, adaptable to each situation, is the farming method common to all four quadrants.

Sécession - Négotiation

Structural exploration: with molasse as a primary building material, the first thing to do is to understand its nature and properties, so as to be able to deduce an effective construction system. A rammed earth structure made of molasse works under compression, and the thickness of the walls increases drastically as a function of the loads. This is why the height of the initial construction was reduced, and the dimensions of the load-bearing structures were revised.

The Ovens was a project to build a housing cooperative in the small town of Burtigny, in the Vaud countryside. The project on display is the result of site visits, discussions with local residents and a manifesto drawn up at the same time to establish guidelines for the project, from the materials used for construction, to the handling of the dwellings and the communal spaces.

Burtigny - A subtle balance between full and empty

Being in peace and quietness, eating under the apple tree, greeting your neighbour, picking vegetables from the garden, chatting with the farmer, seeing children playing in the alley, meeting in the grocery shop... Living in this village is first of all to be part of it.

Living in this village is first of all to be part of it: for this, the project tries to be in tune with the authentic atmospheres that belong to the identity of the village. By observing and analysing, it is important to note the intrinsic qualities of the village.

In Burtigny, the old farming constructions cohabit in harmony with the residential buildings built over the last few decades. A road divides the village in two and is the backbone of the urban organization of Burtigny.

The proximity and the clear delimitation with the large agricultural landscape, which are inseparable from the identity of the village, are very apparent thanks to the visual openings towards the outside, which are found in all places from the road axis.

Most of the village’s open spaces subtly combine the notion of public spaces, accessible to all, generating a much appreciated and sought-after quality of social life.

It is these qualities that the proposal seeks to preserve and extend.

Underground was a project of an itinerary pavillion between Tunis, Lausanne and Oslo. The aim was to put in place a structure that could be easily dismantled and transported from town to town, generating as few emissions as possible. The pavilion also had to have the capacity to remain for an indefinite period in each of these cities. A container was provided, defining the maximum volume that could be transported. The choice was made to transport only the wooden partitions and furniture. The vaults would each be quickly built on site using guides and mud bricks.

The tree house project was carried out during the internship in an architectural office. As the plot is surrounded by a dense forest, the objective was to make the building benefit as much as possible from its context, without making too aggressive an intervention.

The Nests was a project in the ‘‘Tiergarten’’ in Berlin, Germany. The question of this exercise was : ‘‘Is it possible to mix a school’s architecture with the one of a zoo? Can it work?’’. A randomly chosen animal -in this case, the bird- was to be coupled with a school construction in order to find a viable solution to this question.

Prism was a project in the ‘‘Zoo de Servion’’ in Servion, Switzerland. The objective of this research was to offer a pedagogical space for kids. The prefabrication aspect was a particularly important subject of this project, as the pavillion was to be built by students and then moved from its temporary to its definitive site after a year.

Inspired by the orangeries, the play of light and the pleasant temperature offer a warm environment for the exotic plants of the zoo and an interactive space for the visitors. By accessing the prism, they immerse themselves in a world of discovery and exploration.
