Urban-Think Tank is an interdisciplinary design practice dedicated to high-level research and design on a variety of subjects, concerned with contemporary architecture and urbanism.
The philosophy of U-TT is to deliver innovative yet practical solutions through the combined skills of architects, civil engineers, environmental planners, landscape architects, and communication specialists. In 1993, 
founded U-TT in Caracas, VZ, and in 1998, 
joined as co-director. Since 2007, Brillembourg and Klumpner have taught at Columbia University, where they founded the Sustainable Living Urban Model Laboratory (S.L.U.M. Lab), and since July 2010, they hold the chair for Architecture and Urban Design at the Swiss Institute of Technology, ETH in Zürich. Their work concerns both theoretical and practical applications within architecture and urban planning. Working in global contexts by creating bridges between first world industry and third world, informal urban areas, they focus on the education and development of a new generation of professionals, who will transform cities in the 21st century. They have been awarded the 2010 Ralph Erskine Award from the Swedish Association of Architects for their innovation in architecture and urban design with regard to social, ecological and aesthetic aspects.
Operating with offices in Caracas, São Paulo, New York, and Zürich, U-TT is positioned to serve clients and work on projects all over the world.
