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.

The new Hauts-de-Seine Departmental Administrative Center consolidates all State services within a single building. PCA-STREAM leads a major transformation that combines functional reorganization with the rehabilitation of an existing modernist structure. The project rationalizes circulation flows, clarifies access hierarchies, and groups entities by function to enhance legibility and efficiency. Office floors are redesigned as bright, flexible, and cross-ventilated workspaces aligned with contemporary working practices. Respecting the architectural language of the original building, the intervention upgrades thermal comfort and energy performance while introducing carefully calibrated daylight. The result is a coherent, efficient, and enduring civic infrastructure : a renewed framework for public service at the heart of Nanterre.
