Allert Warners was born January 3, 1914, in Amsterdam, the eldest son of architect Filip Anne Warners (1888-1952) (See WARS). In the early 1930s, Warners spent some time in Lausanne, Switzerland, where he attended the Ecole de Métier for a year and gained practical work experience with architect Taroni (?). Back in the Netherlands, he graduated from the MTS in Amsterdam, and in 1936 he joined his father's firm as a supervisor-draughtsman. There he worked on several projects, including the Erdal factory in Amersfoort (1936-1937); 18 single-family houses on Keizer Karelweg in Amsterdam (1937); a sailmaker's workshop on Oosteinderweg in Aalsmeer (1937, independent work); villas in Tilburg, Apeldoorn and Amsterdam (1938-1940); `Het Brouwerswapen' on Rembrandtplein in Amsterdam (1938-1976 demolished); café `Het Gouden Hoofd' in The Hague (1939) and two office buildings for the AVRO on Keizersgracht in Amsterdam (1940-1941). From 1936 to 1943, A. Warners attended the Amsterdam H.B.O. school, where he was taught by, among others, P. Verhagen, J.H.Groenewegen, F.A. Eschauzier, J.F. Berghoef and B.T. Boeyinga. In 1944 he worked together with an H.B.O. classmate G.M.G. Bakker, the later city architect in Zaandam. After World War II, Warners studied at the Stockholm Academy from 1946 to 1947 and made several trips through Europe (Scandinavia, Germany, France, Spain, Italy and England). His postwar works include a hotel bar in Noordwijk aan Zee (1948) in collaboration with painter Jaap Bouhuys; design for a residence with practice in Baarn (1949); single-family houses in Noordwijk (1950); remodeling and expansion of the Hollandse Bank Unie (HBU) on Keizersgracht in Amsterdam (1951); a villa for the director of HBU in Amstelveen (1951); apartment buildings A and B in A[msterdam] and Storey houses on Prinses Irenestraat in Amsterdam. Warners was consulting architect for the Amsterdam Society for the Exploitation of Storey Houses. Allert Warners participated in a number of competitions: for the Town Hall in Schiedam (1950) and the Idea Competition for building a Polder Tower in Emmeloord (1951). After the death of his father in 1952, he continued the firm. He designed four residential houses in Noordwijk aan Zee (1952-1953); the roof structure (1954-1955) for his father's Atlanta office building (1928) on Leidsebosje in Amsterdam; stores and apartments on Slotermeerlaan/Lodewijk van Deysselstraat in Amsterdam (1956) and a school on A.J. Ernststraat in Amsterdam (1963). Warners had a keen interest in contemporary arts and technology. His greatest hobby in addition was sea sailing, which he practiced passionately and successfully; he won a prize with the Sea Eagle in the Fastnet Race in 1937. Among Warners' last projects is the work he made for the work group Densification Building Amsterdam in 1978-1979. This working group, of which Warners was a member, studied two locations (Buitenveldert and Bijlmermeer) in Amsterdam. The urban development bureau W. Wissing made an inventory of the urban planning possibilities for densification, and Warners made idea sketches for the filling of the situations eligible for densification in Buitenveldert. Allert Warners died in Amsterdam on June 18, 1980.
