Celobert Arquitectura, Enginyeria i Urbanisme SCCL operates as a cooperative studio in Barcelona, Spain, with partners including architect Helena Trias Prats and co-founder Diego Messa. It focuses on architecture, engineering, and urbanism, emphasizing housing policy, territorial planning, urban regeneration, and citizen participation.
The cooperative contributed to the Barcelona Housing Plan 2016-2025, coordinating its drafting alongside Lacol and running 21 participatory sessions across the city's ten districts to address emergencies, proper housing use, affordable stock expansion, and renovations. In 2015-2016, this effort updated the prior 2008-2016 plan with 59 action lines.
A key project, Cirerers cooperative housing completed in 2022, stands as Barcelona's tallest cross-laminated timber building at eight floors in one block. It incorporates communal hallways for socializing and environmental measures under a cooperative management model. Celobert also collaborates with groups like Sostre Cívic on similar housing in Barcelona and Calonge.
Trias, who lectures at the Polytechnic University of Catalonia, highlights the studio's cross-disciplinary push for sustainable, people-centered territorial projects. Based at celobert.coop, it maintains a low-profile presence amid Barcelona's architectural scene.
