b720MN19 is an exercise between record, meaning, and the use of color, particularly the association between glass and color. This book is the materialization in paper of a b720's studio the transformation of an anonymous building into a living project as it changes with the passing hours through the colors of the glass slats that transform the interior and exterior in intense dialog with each other. The project also symbolizes the justification of an aesthetical solution to the need for protection from the sun. The work arouses, through the pictures by Rafael Vargas, reflections on project and color in ... the architectural and artistic world.¨ Dominique Boudet, French journalist and critic.
