The year 2007, before the break imposed by the crisis of the sector, we decided to undertake a double way to be able to continue all together in the office. In one hand, opening the office to work in other countries, not occasionally, but systematically, presenting us to competitions, most of which we lost (to fish you have to go where there are fish) and, on the other hand, document the work of those first 20 years. Fruit of this systematic work would be the first of the 14 books that we have edited today and that was presented in the auditorium of the Architects Association in 2008 with success of public and sales. That made, in addition to the friendship that binds me with the Cooperative that this one will publish a small book gathering the presentations of the day of the presentation. Texts by Lluis Cometón, Rogers Pallarols, Félix Arranz, Jose Juan Barba, Manuel Gausa, Ricardo Guasch and Jose Miguel Roldán, many of whom wrote essays of the monograph.
