Chocoladefabriek Pette-Boon

The Pette-Boon complex is an industrial site in Zaanstad featuring a striking cacao tower and concrete production facilities that showcase early twentieth-century factory design. The buildings form a coherent architectural group arranged around central work areas, creating a complete manufacturing landscape of that era.

The chocolate factory began operations in 1872 and reached its peak production capacity during the 1930s before passing to new ownership in 1937. This change marked a significant shift in how the facility operated and influenced its development throughout the twentieth century.

The site embodies the New Building design principles of the 1920s, with its bold reinforced concrete forms reflecting an era of industrial modernism. Visitors can see how these structures served as a living laboratory for new construction techniques that became influential across Europe.

The restored complex now houses residential apartments, shops, a public library, and office spaces open to visitors exploring the site. The layout makes it easy to walk around the exterior and view the architectural features from different angles.

During renovation in 2003, engineers split the main production building down the middle to prevent structural stress from temperature fluctuations. This bold solution allowed the building to expand and contract naturally without damaging its historic form.
