The business began in 1870 in Brussels, Belgium, initially making axles later producing horse-drawn carriages. It was founded by Guillaume van den Plas, a blacksmith, and his three sons, Antoine, Henri and Willy, who later set up a branch in Paris. In 1884 they moved from Brussels to Antwerp. With increased business they opened a branch in Brussels again in 1890. By 1900, they worked with De Dion Bouton, Berlier, Germain and Packard. By 1908 Carrosserie Van den Plas had a workforce of 400 men producing 300 special bodies a year, and that soon increased to over 750. The French branch ceased production in 1934 while the Belgian business was active until 1949.
