InnovatiON-Architecture compiles ON-A work philosophy: a constant search for innovative ad hoc solutions for each project, using the most updated technologies and design research at the service of ideas, with criteria based on their professional career, but always going beyond the conventional. The contents of the book have been organized illustrating the four conversations held between Eduardo Gutiérrez and Jordi Fernández (ON-A founders and principals) and Ricardo Devesa (editor). With the aim of understanding the different degrees of innovation on how they operate in ON-A, the book is organized into these four blocks.

That methodology allows them to visualize and interact with the continuum
