Campus HEC

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.

Tour Bretagne

The new Tour Bretagne, a renovation of the emblematic Nantes landmark, offers an opportunity to transform a symbol of the postwar boom, now obsolete, by adapting it to the challenges of our time. The PCA-STREAM – MAGNUM team enhances its elegance and slenderness by converting office spaces into housing, making the project a forerunner of a new era for the city and the metropolis.

Talleyrand

At the heart of the 7th district of Paris,  PCA-STREAM has transformed what was formerly a bland and common office building into an exceptional town house. The existing building has had its interior restructured so as to provide natural light, while the facades now possess a contemporary identity through a geometrisation of its volumes.

Transvaal

In 2000 PCA-STREAM transformed a former tinplate stamping factory in Belleville, Paris 20e, into a residential loft. Taking advantage of the initial depth of the space, the existing wooden structure has been preserved and the space gutted so as to insert sequences of life around a luminous patio that also provides an interior garden.
