Teun Koolhaas
Teun Koolhaas (7 January 1940 in Singapore – 3 October 2007 in Amsterdam) was a Dutch architect and urban planner.

Early years
Teun Koolhaas was born in Singapore, where his father, Rem Koolhaas, worked as a shipbuilding engineer. When Southeast Asia was occupied by Japan, Teun and his mother were imprisoned in Tjideng camp in Batavia. After the end of the Japanese occupation of Indonesia, the family was reunited, and they moved to Hong Kong. In 1955 Koolhaas returned to the Netherlands to complete his secondary education. He then went on to study engineering at the Technical University of Delft, where he attended lectures by artists including Gerrit Rietveld and Cornelis van Eesteren. After graduating in 1967 Koolhaas continued his studies at Harvard University and MIT in the United States. At Harvard, he earned a degree in urban planning.

Work
In 1969 Koolhaas returned to the Netherlands, where he went to work for the architectural firm, Environmental Design SA. Among other things he designed the dentistry school building at the University of Utrecht in the Uithof complex. Today, the departments of biology and pharmaceutical sciences are located there. The official name is the F.A.F.C. Went Building (after the botanist Frits Went).

In 1972 Koolhaas began working for the National Office for the IJsselmeer Polders (RIJP). As part of a team of architects, urban planners, sociologists, traffic planners and landscape architects, Koolhaas played an important role in creating the master plan for the new city of Almere in the south island of Flevoland, and was responsible for its urban design. 

In 1981 Koolhaas left the Almere project and moved to the regular organization of the RIJP, where he was involved in the design of Zeewolde, and made designs for Markerwaard, a polder that was never built.

In the mid-eighties Koolhaas started out on his own, and founded Ontwerpbureau Ir. Teun Koolhaas Associates (TKA). TKA's work included the master plan for Kop van Zuid in Rotterdam.

In 2003, suffering from cancer, Koolhaas left TKA but continued working almost until his death in October 2007; he was commissioned by the municipalities of Almere and Amsterdam to design the new town Almere Pampus.

Family
Teun Koolhaas is the father of actress Betje Koolhaas. Author and screenwriter Anton Koolhaas (father of architect Rem Koolhaas) was his paternal uncle.
