In 2018, Geoffroy participated in a group show at the Kunsthalle Mannheim called “Constructing the World”, an exhibition examining the 2008 financial crisis, its effects on art and the contrast of this against past economic collapses. Other participating artists included Thomas Hirschhorn, Andreas Gursky and Jeremy Deller. Geoffroy exhibited several of his tent sculptures throughout the whole museum, having the opportunity to juxtapose his tents statements with other artworks from the museum collection, for example Joseph Beuys Filzanzug and Max Ernst's Capricorne, as well as land art pieces and Neue Sachlichkeit artworks. During the exhibition, he also organized Critical Runs.
