For the IABR 2012 (International Architecture Biënnale), Defacto was worked on the project of the ‘Rhine Meuse Delta’. In this project, Defacto researched the opportunities of the current water safety strategy in the Alblasserwaard region. On april 19, the exhibition of the project was opened in Het Nieuwe Instituut by Delta Commissioner Wim Kuijken.

The IABR (International Architecture Biennale Rotterdam) of 2005 is built around the theme ‘flood’. The second architecture biennale evolvesaround the relationship between water and urban design in the Netherlands and beyond. The S-house, a design for a flood-proof dwelling by Anne Loes Nillesen, Peter Miller and Canan Saridal, was exhibited in the NAI (Dutch Institute of Architecture) as part of the IABR2005.
