After completing their studies and various jobs, the four decided to work together in the early 1950s. The office was established in Rotterdam. In 1955, the collaboration was formalized in the form of a partnership. The first major assignments were the construction of the R.K. Bethlehemkliniek (The Hague) and the renovations of the Pier (Scheveningen) and the Jaarbeurshal (Utrecht). This was followed by the construction of the Dutch Embassy in New Delhi, India. In the 1960s and 1970s, the firm was very active with housing projects. Later assignments included the Ministry of Foreign Affairs in The Hague. In 1988, the four founders quit. The agency continued for a short time, but was dissolved as early as 1990.
