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, Alfredo Brillembourg and Hubert Klumpner founded U-TT in Caracas, Venezuela. Since 2007, Brillembourg and Klumpner have taught at Columbia University, where they founded the Sustainable Living Urban Model Laboratory (S.L.U.M. Lab). 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.
