Factory Building on the Vitra Campus is the result of incredible work by the Japanese architects Kazuyo Sejima and Ryue Nishizawa, who founded the studio SANAA almost 20 years ago, and won the Pritzker prize in 2010.

The single circular factory is used by Vitrashop, a shop fitting company within the Vitra Group. Its interesting shape is explained:

This proposal, which at first seemed unusual, was based on the realization that logistics and production methods no longer adhere to strictly hierarchical principles, but require flexibility. This was especially true in the case of the future occupants of the new facility. The circular footprint of the building permits the delivery and loading of goods in completely different locations, so that the flow of traffic inside the hall is reduced, optimized and simplified.

The factory is more than 160 metres in diameter and reaches 11.4 metres in height, with a singular and characteristic facade, made of acrylic glass with three wave patterns on the  surface to avoid a visual repetition, seeming infinite and homogeneous.
