As Milan Design Week concludes, one installation that has resonated deeply within the global design community is "House of Polpa," a groundbreaking collaboration between MIT professor and architect Carlo Ratti and Italian food giant Mutti. This temporary architectural structure, ingeniously crafted from 20,000 cans of Mutti tomato pulp, transformed an everyday pantry staple into an immersive, multi-sensory experience, sparking critical discourse on design, sustainability, and the circular economy.

An Unconventional Canvas: The Genesis of House of Polpa

The "House of Polpa" emerged as a highlight of Fuorisalone, the decentralized events complementing the main Salone del Mobile fair during Milan Design Week. Known for pushing the boundaries of conventional design, Fuorisalone serves as an urban laboratory where architects, designers, and brands showcase innovative concepts across Milan’s historic palaces, courtyards, and public spaces. The Università degli Studi di Milano, a venerable institution with its grand porticoes, provided a fitting backdrop for Ratti’s latest endeavor. The choice of venue itself underscores the project’s ambition to integrate cutting-edge design into the fabric of daily life and historical contexts.

The installation, spanning over 25 meters, manifested as a striking red cylindrical tunnel, its walls meticulously composed of thousands of Mutti tomato pulp cans. These cans were not merely decorative elements but integral structural components, supported by a sophisticated steel substructure. This engineering feat allowed for the gradual and safe removal of individual cans without compromising the overall stability of the monumental structure, a critical aspect of its "ephemeral by design" ethos. The visual impact was immediate and arresting: a vibrant, monolithic form challenging perceptions of industrial packaging and its potential for architectural expression. It evoked a contemporary echo of Andy Warhol’s iconic pop art, which decades ago elevated the humble soup can to a symbol of consumer culture, demonstrating the enduring cultural presence of canned goods.

Beyond the Visual: A Multi-Sensory Journey Through the Tomato Supply Chain

The true genius of "House of Polpa" lay in its ability to transcend purely visual aesthetics, inviting visitors into a profound multi-sensory exploration. Stepping inside the crimson volume, guests were enveloped in an environment designed to evoke the intricate journey of the tomato, from field to table. Subtle yet potent cues of scent, texture, and sound were meticulously integrated to create an immersive narrative. The faint, fresh aroma of ripe tomatoes, perhaps subtly diffused or naturally emanating from the sheer volume of product, hinted at sun-drenched Italian fields. Tactile elements, whether through the exposed surfaces of the cans or specially designed interactive points, offered a physical connection to the raw material. Acoustically, a carefully curated soundscape might have included the rustling of leaves, the hum of machinery, or even the gentle bubbling of simmering sauce, guiding visitors through the various stages of the tomato supply chain.

This deliberate engagement of multiple senses aligns with Carlo Ratti’s long-standing philosophy and the work of his firm, Carlo Ratti Associati (CRA), and the MIT Senseable City Lab. Ratti’s projects frequently explore how digital technologies and sensory experiences can redefine urban spaces and human interaction, blurring the lines between the natural and artificial, the physical and the digital. "House of Polpa" exemplified this by using a low-tech, organic product to create a high-impact, experiential space, demonstrating that profound engagement doesn’t always require complex digital interfaces. It was a testament to the power of design to tell a story and evoke a deeper connection to everyday objects and processes.

Embracing Circularity: A Design for Dissolution

At the core of "House of Polpa" was an unwavering commitment to circularity and sustainability, principles that are increasingly vital in contemporary design and architecture. Every element of the installation was conceived with its lifecycle in mind, actively countering the prevailing "take-make-dispose" model. The flooring, for instance, was a remarkable innovation developed using a Mapei resin derived from dried tomato peels, a significant waste product from tomato processing. This direct transformation of agricultural waste into a high-performance building material not only reinforced the project’s ethos but also showcased tangible solutions for industrial symbiosis and resource recovery. Mapei, a global leader in building materials, leveraged its expertise in sustainable formulations to create a functional and aesthetically integrated surface that literally grounded the exhibition in its circular mission.

The most compelling aspect of the project’s circular design was its inherent ephemerality. Unlike traditional art installations often destined for storage or disposal, "House of Polpa" was designed to gradually dissolve. Visitors were invited to participate in this dissolution by removing a can of Mutti Polpa as they exited. This act transformed passive viewing into active engagement, making each visitor a participant in the project’s dispersal. The symbolic gesture of consumption extended the exhibit’s life beyond the confines of the gallery, into countless kitchens across the region, where the tomatoes would fulfill their intended purpose.

For the cans that remained after Milan Design Week, the commitment to social responsibility continued. These remaining cans were not discarded but donated to local food banks and charitable organizations, ensuring that the valuable food product reached those in need. This thoughtful approach minimized waste to an unprecedented degree, demonstrating how design can operate within a truly closed-loop system, where every component has a subsequent use or destination. The project became a powerful real-world example of how to "design beyond single use," offering a hopeful model for future temporary structures and exhibitions.
