He was educated at the School of Fine Arts, where he studied engraving with J. Pascó and A. Riquer, and later went to study in Paris and Madrid.

In 1907 he went to work in A. Gaudí's workshop on the Temple of the Sagrada Família. He collaborated with A. Gaudí on La Pedrera (1906-1910; Passeig de Gràcia, 92 - Provença, 261-265) and with this architect and Joaquim Torres-Garcia and Iu Pascual from 1904 to 1914 on the stained glass windows of Palma cathedral in Majorca.

He designed many bookplates in the Modernista style (Ex-libris de Joan Llongueras [Bookplates by Joan Llongueras], 1904; MNAC collection). However, his main activity throughout his career was interior decoration, from the Royal café restaurant (1910; Rambla, Barcelona; no longer in existence), which won the Barcelona City Council Prize in 1911, to the mayor of Barcelona's office, in 1929.
