This is an overview of 30 innovations, spaces and techniques made in Catalonia. The publication presents a cross section of 'products', constructed buildings and produced environments. Each 'patent construction' represents a solution to specific functional requests, social demands, environmental requirements, and budget limitations, and the desire to improve the construction process. Designed and produced within specific contexts, these innovations define new architectonic solutions, where the protagonists are not the buildings, but the ground-breaking patents and prototypes.
