Modern architecture has a significant impact on Förg’s works, becoming a central focus in his photography in his images of Bauhaus architecture in Tel Aviv and the IG Farben Building in Frankfurt am Main, as well as in his paintings. In the 1990s, many of his large-scale lattice images were created, demonstrating Förg‘s understanding of how to unite geometric rationality of form with an intuitive color scheme, to create moods and advance discussions. Förg’s works has been widely exhibited internationally. He has been historically categorized as an abstract and Minimalist artist (though his work does include some figuration).
In 1992, he was represented at the Documenta art fair, and in 1996, he won the Wolfgang Hahn Prize. His work can be seen in collections of the Hamburger Bahnhof in Berlin, the Kunstmuseum Bonn, the Museum für Moderne Kunst in Frankfurt am Main, and the Galerie für Zeitgenössische Kunst in Leipzig, among others.
