PCA-STREAM is an urban and architectural design firm based in Paris. The wide range of missions it undertakes is remarkable in the industry. PCA-STREAM brings together a team of 90 collaborators of diverse backgrounds and talents: architects, city planners, engineers, designers, artists, researchers, editors, and the like. Its multidisciplinary team and the variety of scales and projects that the members undertake have made them experts in building with a holistic view of global processes and issues.

The practice in numbers :
— 87 collaborators
— 43 women
— 44 men
— 13 nationalities
— 25% of foreign collaborators
— Average age: 36 years old
— Parity index: 74%

Gender equality indicators:
— Pay gap: 39/40
— Difference in the rate of individual increases: 35/35
— Percentage of female employees who received a raise upon returning from maternity leave: 15/15
— Number of employees of the under-represented gender among the 10 highest paid: 10/10
— Gender equality index: 99/100

The firm is comprised of a transversal and multidisciplinary research cluster (STREAM LAB), a design hub (which works on a wide variety of topics that range from urban planning to interior architecture), and an operational unit (whose teams work directly on construction sites). Thanks to the transfer of knowledge and the continuous dialogue between these different hubs of experts, the firm cross-fertilizes its modus operandi and its way of thinking.

Understanding the big picture

Research informs PCA-STREAM’s global and multidisciplinary understanding of the transformations and challenges facing the world today. The firm brings together thinkers, researchers, and entrepreneurs from all walks of life, to accompany it in the different stages of its projects. Research is conducted at the STREAM LAB and findings are disseminated: both digitally, on its web platform, and in print, in the book-magazine STREAM.

Building strategies

Economic globalization, the urban explosion, the digital revolution, and the environmental crisis are new challenges facing the world today. An in-depth understanding of these transformations and of their impact on new uses gives PCA-STREAM a forward-looking vantage point that it uses to formulate innovative programs. These programs are adapted to the world of tomorrow and to the territories in which they will be constructed. STREAM LAB’s role is to produce the strategic studies that will help shape the projects.

A nexus of collaboration

The firm calls on an extensive network of multidisciplinary partners with whom it develops advanced collaborative project processes. PCA-STREAM is always looking out for fresh perspectives, be they from start-ups, non-profits, communities, researchers, designers or artists. Thought leaders are invited to take part in projects or to share their vision in the articles or talks that are disseminated on PCA-STREAM’s platform. Over the years, the firm has formed a network of trusted expert partners that is key to renewing its outlook and design.

Bold design

PCA-STREAM’s expertise covers a wide spectrum of scales of intervention. Its dedicated team of interior architects is passionate about interior architecture; its architectural projects to date range from 500 to 110,000 sqm; and it is even involved in urban planning projects. PCA-STREAM is proud not to limit itself to a narrow specialization at a time and age where programmatic thinking appears to be key to transforming cities. PCA-STREAM tackles all types of programs as long as there is a desire to reinvent them: offices, commercial spaces, museums, housing, hotels, skyscrapers, and even whole urban districts.

Research findings can only be tested out in construction projects: beyond theory, architecture must prove itself and pass the test of production and use. Over the past five years, PCA-STREAM has thus constructed almost 200,000 sqm of urban space, and an additional 150,000 sqm are scheduled in the next two years. The firm is renowned for its capacity to run construction sites and architectural projects as well as large-scale urban projects of great complexity. To improve its performance, PCA-STREAM draws on specialized collaborators and partnerships with general contractors, and conducts feedback workshops and satisfaction surveys after the interventions are put in place.

Promoting the projects

Since its inception, PCA-STREAM has painstakingly documented its projects from the first stages of construction to the buildings in use. In order to be able to look back on its architectural developments, PCA-STREAM has an integrated editorial expertise with PCA Éditions, which regularly publishes work that retraces the adventure of a given project. Its publications, documentaries, films, and articles are shared on its digital platform and aim to bring together those who will make the city of tomorrow and its extended community.
