Ordos 100 is a construction project curated by Herzog & de Meuron and Ai Weiwei.

One hundred architects from 27 countries were chosen to participate and each design a 1000 square meter villa to be built in a new community in Inner Mongolia. The 100 villas would be designed to fit a master plan designed by Ai Weiwei.

On January 25, 2008, the 100 architects gathered in Ordos for a first site visit. The film Ordos 100 documents the total of three site visits to Ordos, during which time the master plan and design of each villa was completed. Until today, the Ordos 100 project remains unrealized.
