Estudio ODS is an architecture studio established in Portugal's Algarve in 2010 by Marlene dos Santos and Bruno Oliveira. Both founders studied architecture at the University of Evora and completed master's degrees in Advanced Architectural Projects at ETSA Madrid. Their practice combines architectural work with research, critical reflection and teaching at Evora's architecture department. Each project begins with the particular characteristics of its location and develops through drawings and models made at different scales. The studio seeks simple, efficient solutions rather than a fixed formal approach applied to every brief. Its built work and competition projects have received national and international recognition, including Europan prizes and Algarve architecture awards.
