Both of these buildings, Am Rupenhorn 24 and 25, were built based on designs by Hans and Wassili Luckhardt and Alfons Anker between 1929 and 1932, and are among the very first constructed in the "Neues Bauen" style in Germany, which incorporates architectural elements into the design. Characteristic features include the severe simplicity and the uncompromising cubic structures that are arranged with subtle proportioning of spaces and openings. The innovative structural engineering, the high quality of the artistic design, and the radical redesign of housing all factored equally in these buildings becoming the epitome of modern architecture of the 1920s.
The exterior features in particular exhibited considerable structural damage due to standing empty for so long and intermittent neglect, so that in 1997 and 1998, extensive repairs on the outer shells had to be undertaken, taking into account factors for the preservation of the historical nature of the buildings.
Before the work began, the existing state of the buildings was recorded and their condition evaluated. The results showed that both buildings had undergone different types of renovation measures back in the 1970s. The buildings had been constructed with steel skeletons, and there is an air space between the main structure and the exterior. The exterior of the structure is borne on wooden laths, and the plaster is attached to the exterior by means of wood wool slabs and expanded metal of various dimensions. The inspections of the paint on both buildings showed that the facades had originally been painted with white oil and wax based paint. The previous renovation measures from the 1950s and 70s resulted in intense but varied encroachments into the outer shell of both buildings.
