The Soul of a Modernist Block: How SOM Reimagines Milan’s Corso Italia 23 as a Porous Urban Campus
Personally, I think the most striking move in SOM’s retrofit of Corso Italia 23 isn’t the glass-and-granite facelift—it’s the audacious reimagining of a closed-off ensemble into a living, porous urban campus. What makes this particularly fascinating is that the project respects the original mid-century mindset while insisting that a 1960s office complex can participate in today’s open, climate-conscious city fabric. In my opinion, this balance between preservation and redefinition is less about style and more about reestablishing how work and public life mingle in a dense urban setting.
A new kind of campus, not a relic
SOM’s approach treats Corso Italia 23 as a material archive rather than a demolition target. They retained about 70 percent of the existing structure and foundations, a move that signals a belief in memory as an asset rather than a constraint. The result is a building that still wears its Gio Ponti and Piero Portaluppi heritage on its bones, but speaks a modern language in how people move through and use it. What this really suggests is a shift in architectural ethics: you can extend the life of a landmark by injecting contemporary values without erasing its identity.
From a closed block to a permeable campus
The core transformation is functional as much as it is symbolic. The original layout, praised for its geometric discipline, had become insular and unwelcoming to everyday life. SOM’s solution: create a porous, verdant campus where people circulate with ease
- replacing a central parking courtyard with a shared garden
- stitching together fragmented internal routes with new pedestrian paths and staircases
- introducing glass-enclosed entrance lobbies that frame views into the courtyard
This isn’t just cosmetic openness. It reconfigures the building’s physics—allowing daylight deeper into interior spaces, enabling spontaneous encounters, and lowering the psychological distance between “inside” the workspace and the city outside. From my perspective, the garden as a social condenser is the piece that makes the whole project feel alive rather than museum-like.
Material memory as a sustainable strategy
SOM’s reuse strategy isn’t a rhetorical gesture; it’s a practical argument about embodied carbon. By keeping most of the structure and foundations, the project reduces the energy and emissions that would have come with new build-out. Even where material substitution was unavoidable—like the damaged red granite façade—the team repurposed it into a glass-fiber reinforced concrete system that mirrors the original hue. What many people don’t realize is that this kind of circular thinking is a form of climate design: it treats the building as a resource bank rather than a disposable shell.
In my view, this approach reframes what “sustainability” means in architecture. It’s not only about energy codes or LEED points; it’s about preserving material storytelling while delivering modern performance. The result is a building that feels responsible, not retrofit-for-the-sake-of-it. If you take a step back and think about it, the poem here is continuity—continuity of craft, of urban life, and of a city’s memory—polished with the urgency of today’s environmental realities.
New spaces, new rituals
Inside, the plan opens up with large spiral staircases and redesigned floor plates that encourage vertical and horizontal movement, turning circulation into a design feature rather than a bottleneck. The addition of lounges, breakout spaces, and roof terraces redefines how workers experience the building. It’s not just about more space; it’s about better space—the kind that invites conversations, collaboration, and a sense of belonging. From my standpoint, this is where traditional modernist blocks often stumble: the interiors feel monument-like, but not inhabited. Corso Italia 23 now aspires to be inhabited, daily and publicly.
A broader tide in postwar architecture
The Milan project sits within a growing current of adaptive reuse that treats mid-century modernism as a living archive rather than a closed-off museum. Across different continents, studios are reclaiming old industrial and office blocks, reimagining them as campuses, marketplaces, and cultural hubs. What makes Corso Italia 23 compelling is how it weaves a narrative of memory with a forward-looking urbanism: porousness, public accessibility, and sustainability acting in concert with architectural form.
What this means for the city
From my vantage, one of the most important implications is urban metabolism. Buildings that once stood as isolated blocks are becoming nodes in an active, legible city network. Pedestrian routes, sightlines into shared courtyards, and publicly accessible entrance lobbies tie Corso Italia 23 into the street life rather than isolating it behind an anonymous façade. This is not just about aesthetics; it’s about urban empathy—design that invites people to stop, meet, and linger rather than pass by.
A note on perception and time
There’s a delicate tension in preserving a “soul” while upgrading for contemporary performance. The studio’s claim—that the soul remains even as the insular logic gives way to openness—speaks to a broader philosophy: authenticity in architecture isn’t about keeping everything the same; it’s about keeping what matters and reinterpreting it for current lives. What this perspective underlines is that time, when treated thoughtfully, can be a collaborator, not an adversary.
Conclusion: a blueprint for humane modernization
Corso Italia 23 isn’t merely a retrofit; it’s a manifesto for how to honor architectural legacies while meeting today’s social and environmental imperatives. Personally, I think the project offers a pragmatic blueprint: respect the material history, restore legibility to complex relationships, and reframe the building as a living part of the city, not a relic sealed off from it. If cities want to grow without erasing their past, more projects should follow this example—where memory, sustainability, and everyday life converge in a single, porous, human-centered campus.
