Nestled in the heart of the Bièvre Valley, the HEC campus embodies the living archive of modern tensions between nature and knowledge, heritage and forward-thinking. In a world undergoing transition, the school chooses to revisit this exceptional environment and integrate it into a sustainable, inclusive, and ambitious strategy. PCA-STREAM proposes a project that is both contextual and transformative: restoring coherence to a fragmented domain, reactivating landscape and social continuities, and creating a new embodied centrality : the Campus Heart, to give form to the HEC of the 21st century. A place of learning in and with the landscape. A campus aligned with its time.

With Porta Romana project, PCA-STREAM design a new destination and landmark for Milan. At the threshold of Scalo di Porta Romana, what was once an urban limit will become an environment of opportunities. PCA-STREAM as the ambition to bring an iconic presence to the area, to offer a new physical and symbolic gateway to the Scalo zone. Around the two monumental staircases, three buildings will flourish with commercial, tertiary, and leisure programming thanks to strong public spaces with nature at the heart of the urban program. Porta Romana exemplify the idea that a buildings’ quality of life, through their planted exteriors, but also the intensity of the urban life of the neighborhood, have become a key factor in their attractiveness.

Mouchotte's project reinvents a landmark modernist complex in Montparnasse to meet the challenges of the 21st century. Its sober and responsible rehabilitation prioritizes reuse and performance while clarifying spaces, reprogramming uses, and enhancing outdoor areas. This transformation aims to restore coherence and appeal to the building, contributing to the renewal of the neighborhood.
Reinterpreting the Original Architecture
Our architectural approach highlights the original qualities of the building while introducing new urban values. Through a refined reinterpretation, the project reinforces the building’s role as a civic landmark, especially from the banks of the Alster. This “re-visibility” turns the structure into a platform for showcasing new urban lifestyles and workplace transformations.
The façade’s original composition plays a key role in the identity of the building. We have chosen to preserve and emphasize its strong horizontality—a defining feature that lends the building its character. The alternating rhythm of black and white tones is maintained and enhanced by a lightening of the façade. The elevation adjacent to the listed palace is treated with deference, using horizontal profiles and interrupted balconies to maintain harmony. Continuous façades further consolidate the identity of the ensemble, with a unified base matching the tones of the surrounding urban fabric.
Responding to New Lifestyles
The project fosters a dynamic mix of functions by opening the ground level to the city, activating it with restaurants and shops that serve not only residents and workers, but also draw visitors from beyond the neighborhood. A communal courtyard with shared facilities supports flexible, evolving uses—by day, by night, and through the weekend.
For longer stays, a dedicated Long-Stay zone between hotel and residence offers a space to relax, work, or host guests in a discreet yet convivial atmosphere. Housing is reimagined through bright apartments on the upper floors, each with private balconies and access to a shared rooftop terrace—designed for gatherings, DIY, games, work, or informal moments between friends and neighbors. All residential units include private, fully equipped green terraces, extending interior life outward and blurring the line between domestic and natural space.
A Holistic and Responsible Vision
Sustainability and exemplariness are embedded in the project’s DNA. The decision to renovate with minimal demolition—focused mainly on the façade—ensures a significant improvement in the building’s energy performance while minimizing its environmental impact. This is complemented by the use of low-carbon materials and construction methods. Given the energy-intensive nature of the existing structure, improving efficiency is a crucial priority.
Greening the inner courtyard and the terraces not only enhances user comfort and spatial quality but also contributes to urban cooling, water management, and biodiversity
