Educated as an architectural engineer at the Technical University in Delft, and as an urban designer at Harvard and MIT, Teun Koolhaas designed the master plan of Almere New Town in The Netherlands at the start of his career in the beginning of the seventies while he worked from within the Lake IJssel Development Authority where he directed the design department. Since 1984, Teun has designed a dozen new or extended new towns with his office Teun Koolhaas Associates (TKA).
With 180,000 inhabitants Almere is now the largest new town in Europe, and the present policy for Almere to grow to 400,000 inhabitants is provided for in his recent IJ Meer Plan with co-designer Ellen Marcusse, which was presented to the national cabinet in June 2006.
In the Netherlands, where half of the country lies below sea level and which has a maritime history, the design and transformation of waterfronts is of national importance. From the very start of its foundation TKA was commissioned to design several major waterfronts. This has resulted in a high level of expertise in this specialized field.
