Carlos has a studio in Madrid, where he conducts projects of a very varied nature. These projects have a special emphasis on sustainable development and research into new forms of housing. Examples include:

• the Cortijo de las Ventajas joint-ownership housing project in Granada (a combination of 2,500 m2 of co-housing with an agribusiness cooperative, and a mixed system of renewable energy production).
• the “Ecobarrio” in Toledo (60,000 m2 of housing designed for other compatible uses as well, developed with Eleonora Guidotti and Manual Pérez Romero, upon winning the Europan Award).
• the H↔H Project (a research project to determine the real demand for new forms of housing in Spain, conducted together with Eleonora Guidotti and the sociologist Virginia Godoy).
• involvement in different projects to develop housing for specific needs: for youth, for the elderly (with shared services), and for extended families.

Carlos has participated in numerous exhibitions, notably the 8a Biennale di Architettura di Venezia. His work has appeared in publications such as El Croquis (No. 119), Bauwelt, Bau, Arquitectura, AV, circo, Fisuras, and ON diseño.

He has been a guest professor and lecturer at many universities and institutes, both in Spain and in the international arena.
