Slow Studio is an architecture firm based in Barcelona, Spain, founded by Víctor Vergés and Jade Serra. The practice is recognized for its emphasis on ecological design and bioclimatic strategies, focusing on residential architecture that integrates energy efficiency and the use of natural materials. The firm’s approach is rooted in a careful, deliberative process that privileges listening to client needs, climatic conditions, and the characteristics of the terrain.
Since its founding, Slow Studio has expanded its presence with offices not only in Barcelona, but also in Madrid and Palma de Mallorca. Their team comprises senior architects, project managers, and external specialists in fields like energy efficiency, acoustics, and biohabitability, activated according to each project's specific requirements.
Among notable projects are the Casa Serra d'Ordal near Barcelona, designed as a biophilic home with a central courtyard to optimize solar gain and natural ventilation, and built with compacted earth, cork, and plywood. Another example is the passive House in Monte el Pardo near Madrid, employing cross-ventilation and natural daylighting strategies, along with low-impact building materials to minimize energy consumption. Their portfolio also includes collaborations with energy-efficiency consultants, such as Societat Organica.
Slow Studio maintains involvement beyond design practice through its “Slow Research” line—internal research and knowledge sharing—and participation with the Architecture and Sustainability Group (AUS) of the Architects' Association of Catalonia, promoting regulatory change and decarbonization in the sector. The firm’s ethos extends into daily life, emphasizing well-being, genuine materials, and connection to nature, both in their projects and professional conduct.
