We are an architecture and art production office based in Madrid, founded in 1999 by PhD Architect Ángel Borrego Cubero. We combine professional services and projects with research work, all of which show our more or less explicit activism for wider democracy and data informed participation, a more inclusive urban planning and socially responsible real estate market, and for a critical and more architecturally driven balance between building, energy and sustainability needs.

Recently we completed Factoría Cultural Matadero Madrid, a reversible architecture project that reuses an existing former industrial space for a creative industries hub. For this project we won the COAM Architecture Award with Special Mention (Chamber of Architects from Madrid, Spain 2015), the NAN Award to Best Rehabilitation Project 2016, the Prize to the Most Innovative Workplace Project at Build Sustainability Awards (UK, 2016) and the Third Prize at RTF Sustainability Awards (India, 2016); the project was selected among the 20 finalists at the XIII Spanish Biennial of Architecture (Spain, 2016) and was a nominee at the European Prize of Contemporary Architecture Mies van der Rohe 2014. It was also a part of the Spanish Pavilion, the Golden Lion winner at the XV Biennale di Venezia (Italy, 2016).

Currently, our most important commissions are: A housing building in a historical building in Cerda´s XIXth century Ensanche neighbourhood, Barcelona; and, after the successful experience of Factoria Cultural Madrid, we are now making the designs for Factoría Cultural’s upcoming headquarters in other cities in Spain.

At public architecture competitions, we won among others, the 1st position in the international competition for the design of the Civil Registry in the wide competition for the Campus of Justice in Madrid, where architects such as Foster, Rogers, Zaera’s FOA and Zaha Hadid also won competitions for other buildings of the Campus. We also won prizes for the design of a mixed use complex in Zaragoza, the competition for the museum and flagship space of Mahou, and others.

Our participation in competitions gave rise to a research project on competitions themselves and their relationship to architectural practice, participation and democracy. This ongoing research, granted with funds from the Foundation Arte y Derecho VEGAP, the Government of Andorra, Creative Industries NL Funds, Universidad Politécnica de Madrid, etc., has given birth so far to The Competition (2013),  the first feature documentary ever to show the entire process of an architectural competition from the inside. The film has been met with global success, and we are in the process of enlarging the scope of the research. On October 10th 2013, The Competition opened the Architecture Film Festival Rotterdam (AFFR), with a 500 people audience. The film has been successfully shown since then in cities across Europe, Australia, United States of America, Latin America and Africa and it was an Official Selection film for important film festivals. The Competition won the Architecture Dissemination Award at the XIII Spanish Biennial of Architecture, in 2016 and it was the first ever non-building project to win the First Prize at the COAM Architecture Awards (Chamber of Architects from Madrid, 2014), perhaps the most important yearly architecture award in Spain.

In collaboration with Natalie Jeremijenko’s X-Clinic and New York University, we’ve designed the prototype Urban Space Station, an advanced greenhouse able to alter the urban buildings in order to enhance quality of life. A 40% of this prototype was built and tested within the exhibition Souls & Machines, Digital Art & New Media, held in 2008, at the National Art Museum Reina Sofía in Madrid. In 2016, a 1:1 prototype was built for the Art Triennial Emscherkunst. Placed on top of an existent building, docked onto the air conditioning of the surrounding buildings, it created a cleaning circulation; the building’s waste air and warmth were filtered by the USSs plants, cleaned, and enriched with oxygen before it was led back into the building.

At OSS we also lead the long-term research Ensanche! / Pump Up Housing! a massive housing rehabilitation program based on our own decision support software. Initially funded by the Spanish Ministry of Housing and the Government of the Canaries Island, it has had other collaborations with universities and local administration. In 2012, this on-going project was a finalist at the Research Prize of the Ibero-American Architecture Biennial, a finalist at the International Festival of Architecture eme3 Bottom-up and was included in the AlterArchitectures Manifesto of the Observatory of Innovative Architectural and Urban Processes in Europe.

OSS’ s works were largely reviewed and published in most important newspapers and architecture magazines across the world: The Guardian (UK), Volkskrant (NL), Clarín (AR), El País (ES), Arquitectura Viva (ES), On Diseño (ES),  Architectural Record (US), AIT (DE), Bauwelt (DE), AMC (FR), C3 (KR) etc.
