U-TT was founded in 1993 by Alfredo Brillembourg in Venezuela. In 1998 Hubert Klumpner joined as a 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 have held the U-TT Chair for Architecture and Urban Design at the Swiss Institute of Technology, ETH in Zürich.
The organisation’s philosophy draws on the combined skills of architects, civil engineers, environmental planners, landscape architects and communication specialists to deliver innovative, but practical solutions to urban issues. Their work concerns both theoretical and practical applications within architecture and urban planning, focusing on the education and development of a new generation of professionals who will transform cities of the 21st century.
