Joan Margarit Consarnau was born in 1938 in Sanaüja (Segarra).

Margarit Consarnau published his first collection of poetry in Spanish, Crónica, in 1975. Since then, he has lived in Sant Just Desvern, where he shares an architecture studio with Carles Buxadé. His most emblematic works are the fruit of this long collaboration: the Museum of Science and Technology of Catalonia, the Áraba Pavilion, in Vitoria, the Olympic Stadium and Ring for the 1992 Olympic Games (in collaboration with Correa-Milà), the campus of the Autonomous University of Barcelona, and the calculations and executive projects for the Temple of the Sagrada Família.
