Industrial and interior designer, he joined the MBM (Martorell-Bohigas-Mackay) architecture studio in 1973. In 1978, he took over the IDP studio, where he developed projects for exhibitions, museums, ephemeral spaces, libraries, stage sets, and signage, among others.
The products designed by Lluís Pau are notable for their minimalism in form. Elemental designs based on the use of materials and structure to shape and use. In short, simplicity and utility.
Some of his designs are part of the permanent collection of the Barcelona Design Museum.
