He has also taught at American universities of Princeton in New Jersey, Illinois Institute of Technology in Chicago; and European Architectural Association in London, EPFL Lausanne, Ljubljana and Alicante.

It has approached the architecture to the world of art in the second half of the twentieth century with collaborations with artists as different kinds Antoni Muntadas or the American Dan Graham.

Herreros presented two projects at that time as the beginning of a new stage: A house on the island of Mallorca and architectural design of the art fair ARCO in Madrid; in which he applied urban criteria for space allocation and management of program uses.

His theoretical work currently focuses on his work and seminars on "Emerging Practices in Architecture" which takes its name from the Research Group directed at the Polytechnic University of Madrid based on the idea of recycling the figure of the architect and his techniques in light of new economic coordinates and the crisis of traditional modes of production which hinder the incorporation of new generations to the practice of architecture techniques.
