The book JLM. Works, Projects, Writings presents a selection of works of the architect Josep Lluís Mateo. For the inside, we chose a simple and highly structured layout, ideal to present the very heterogeneous data and information. For the cover, however, we wanted to give it the feel of a book-object, as if made of the materials’ samples that get sent to architects' studios. So we did away with all the external finishes typical of books, and gave it the aspect of a solid metal object, painting the edges metallic grey and debossing the letters, without ink.
