After studying in Seville and Paris, María and Juanjo founded SOL89 in 2004, a studio from which they attempt to combine research, teaching and architecture. Since then, they have developed projects that have received recognition, such as the 1st Wienerberger Award (Austria, 2014), the 1st Grand Prix Européen d´architecture Philippe Rotthier (Belgium, 2014), the 1st Enor Award for Young Architecture (Spain, 2014) and the 40under40 Award for young European architects from the Chicago Athenaeum (USA, 2015).

They have been finalists and award recipients in the Spanish Urbanism Biennial in 2014 and 2016, have been nominated to the Mies van der Rohe Award in 2015 and chosen to be part of the Spanish Pavilion at the XV Venice Biennale in 2016, which received the Golden Lion.

They are lecturers at the School of Architecture of Seville and their work extends into the dissemination of the architectural thinking as editors, through articles published in specialised magazines and the management of different events, such as the 2013, 2016 and 2017 Acciones Comunes (Common Actions) Seminar on art and architecture at the Menéndez Pelayo International University. They are the authors of the books Proyectos Encontrados (Found Projects) (Recolectores Urbanos, 2012) and El dibujo del mundo (The drawing of the world) (Lampreave, 2014).
