Wilhelm Deiters was the manager of the artists’ colony. His house was designed by Joseph Maria Olbrich, who was also responsible for the ground floor interior. It is the smallest of the houses and its particular form is the result of the quadratic shape of the property on which it is built, which lies at the intersection of two streets. It survived the war unscathed and was restored to its original appearance in 1991-1992 following several less fortunate attempts to renovate and redesign it. The building became the home of the German Polish Institute in 1996.
