He was married to María Arisqueta Pereira, founding member of the Spanish Lyceum Feminine Club and collaborator in Baroja's and Cipriano Rivas Cherif's El Mirio Blanco theatre group.

He studied Secondary School at Instituto Cardenal Cisneros in Madrid. In the "Annual Directory of de Association of Architects of Catalonia" of 1933 he is listed as Graduate of Exact Sciences, Professor of the Architecture College, Professor of the Industrial Arts and Industries Central College of Madrid, as well as Architect of the State Ministry. In 1933 he became chair of the Working College of Madrid, which he came back to work for in 1940 after the Spanish Civil War. In 1952, he died in Madrid.

Regarding his musical career, he stood out as a soloist performer accompanying symphonic orchestras such as the Philharmonic of Madrid, or the Symphony Orchestra of Bilbao. Around the years 1916-1917 of the National Music Society, he performed both the piano and orchestra versions of "Danse sacrée et danse profane" by Debussy with the Philharmonic Orchestra of Madrid. He travelled to Bilbao with Adolfo Salazar in 1917 where, after attending a lecture given by Salazar, he performed works of Franz Liszt, Franz Schubert, Óscar Esplá, Robert Schumann, Béla Bartók, and Isaac Albéniz. He was undersecretary of the National Music Society's board of directors in 1918, run by Miguel Salvador Carreras. Around the time, Adolfo Salazar was the Society's general secretary and its Artistic Committee was formed by Bartolomé Perez Casas, Joaquín Turina, Amadeo Vives, Manuel de Falla, and Conrado del Campo. In 1918 he gave a concert alongside Andrés Segovia and Gaspar Cassadó at the small theatre of Granada's Alhambra Palace Hotel, organised by the Artistic Centre of Granada. He performed, once again with the Philharmonic Orchestra of Madrid, "Noches en los jardines de España" by Manuel de Falla in March of 1921 at the capital's Price Theatre. His repertoire included works of Johannes Brahms, Liszt, Debussy, Maurice Ravel, and Eugene Goossens; as well as Isaac Albéniz's "Iberia", Falla's "Fantasía Baetica", and Oscar Esplá's "Impresiones Musicales". Joaquin Rodrigo dedicated to him the first work in "Tres danzas de España" (1941) for piano, "Rústica", this work having been inspired by the poetry book "Danza Viejas" by Víctor Espinós.

A su muerte, el Real Conservatorio Superior de Música de Madrid compró a sus herederos su biblioteca musical en 1952.
