The MK4 "Friends" residential buildings directly on Hirschgarten, near Munich's main railway station, represent a special form of urban living. All of the surrounding buildings are subject to the same architectural philosophy, creating a holistic image for the entire neighborhood. The cantilevered, jagged façade characterizes the building's appearance. The usable space inside the building has been further extended by curtain-type sheet metal cladding on the unitized façade in a special design. The lively building structure shines through the asymmetrical arrangement of the element types, which Feldhaus prefabricated in the factory to create the best possible joint pattern.
