Paris Builders Show (formerly Mondial du Bâtiment) is the unmissable international event bringing together all building, construction, and renovation professionals at Paris Expo Porte de Versailles from September 28 to October 1, 2026, across four major trade shows: Batimat, Idéobain, Interclima, and Renodays.

 

 

Founded in 1959, the International Building Exhibition—held every two years—evolved over time into the Mondial du Bâtiment before becoming the Paris Builders Show in 2026.

It has brought together the Batimat, Idéobain, and Interclima trade shows since 2013 and incorporated Renodays in 2023.

Originally held at the Porte de Versailles Exhibition Centre, the event moved to the Paris Nord Villepinte Exhibition Centre in 2013, before finally returning to Paris Expo Porte de Versailles in 2022.

 

From September 28 to October 1, 2026, building industry professionals will gather for this major event—the Paris Builders Show—which features 2,200 exhibitors, over 135,000 participants, and more than 500 conferences, while uniting four complementary trade shows:
