J.H. Groenewegen and H. Mieras Johan Hendrik Groenewegen (Amsterdam, 1901) studied architecture at the School of Architecture in Haarlem. In 1928 he established himself as an architect in Amsterdam. Before World War II, he became best known for his designs for the Montessori school in Bloemendaal and several store premises on the Van Baerlestraat, corner of Jan Luykenstraat in Amsterdam. In 1954, Groenewegen associated himself with Hans Mieras, who had been associated with Groenewegen's firm as a draftsman since 1949. Together they developed among other things the now disappeared KLM bus station on the Museumplein in Amsterdam, the 'Hendrik van Boeijen-oord' institution for retarded children in Assen and 138 houses and 12 garage boxes in the expansion plan Westrand in Roosendaal. Groenewegen died in 1958. At that time he was working with the architect A. Rothuizen on the development for the construction of the medical faculty of the Free University in Amsterdam. Groenewegen was a member of the architect group "De 8" before the war and was considered a representative of the Nieuwe Bouwen and the architecture of post-war reconstruction. Hans Mieras continued the Bureau and designed several hospitals. Mieras would pass away in 1997.
