Ozaeta-Fidalgo (Before, TallerDe2 and OZAETA-FIDALGO since 2023) is an architecture practice founded in 2008 by Arantza Ozaeta Cortázar (1982) and Álvaro Martín Fidalgo (1980), established in Madrid, Spain. They conceive their work as a collaborative practice, gathering working teams with members whose diverse backgrounds contribute to achieving high-quality projects with responsible results for a happy life. Their interests focus on the exploration of architecture as a vehicle for urban regeneration, intergenerational care, and socio-environmental challenges, developing initiatives in collaboration with private, municipal and territorial agents in permanent commitment to innovative practice.
They have won and built national and international competitions, and their work has been recognized on multiple occasions, including the Architectural Record Design Vanguard 2025, the German Bauwelt-Preis Award (2013), the COAM-Luis Moreno Mansilla Award (2013), the FAD Award for Thought and Criticism (2016), in collaboration with the HipoTesis publisher, or the Europe 40under40 (2017) by the European Centre. Their work has also been selected and exhibited in the Spanish Architecture Biennial (2013-2021), the FAD International (2014) and the FAD Architecture (2020). Also in the international exhibitions “Archipaper. Dibujos desde el plano” (2018), “Architetus Omnibus?” (2015) or “Export Arquitectura Española en el extranjero” (2015). They have curated the lecture series Argument#1 “Sampling-Contexts” (2019), Argument#5 “Proximities” (2024) and TAG VOL.1 (2024) at the ETSAM, where they are also editors of the homonymous books that were recognized with the COAM-Diffusion Award (2021).
Arantza Ozaeta and Álvaro Martín Fidalgo combine their professional work with teaching and research. They have taught at the AA-Architectural Association School of Architecture in London, ETH Zurich, the Coburg University of Applied Sciences in Germany, and the Madrid School of Architecture (ETSAM), where they currently teach in the Architectural Design Department.
