Tom Steinhöfer once came along with the concept of the "Garden hermit" that he thought he recognized in the role of Friedrich Liechtenstein in Roger Bundschuh's building "Linienstraße 40" in Berlin. Garden hermits - as Wikipedia says - were "encouraged to live in purpose-built hermitages, follies, grottoes, or rockeries on the estates of wealthy land-owners, primarily during the 18th century. Such hermits would be encouraged to dress like druids and remain permanently on-site, where they could be fed, cared-for and consulted for advice or viewed for entertainment." For some reasons we couldn't help ourselves and kept thinking of this from the beginning of this project.
