At the time of the Lords of Winterau, the castle's outer girding wall enclosed an extensive area, as still witnessed today by the cadastral names "Hinter den Ziunen" or "Hinter den Zäunen" (“Behind the Fences”) and "In der Zingel" or "In der Ringmauer" (“In the Girding Wall”). After the Thirty Years' War, the citizens of Heidesheim began to use this wall as a quarry, tearing it down in the process. Andreas Trauttner's 1754 map shows the Windeck already in the shape seen today. The originally open area between the tower and the inner wall is covered by a gabled roof and thus used as a stately home stretching across the north, east and southeast around the tower. In the southwest and west, the wall has been levelled, through which the tower on the building's western edge rises. It is likely that Samuel Beck gave it this shape after 1626. The ogival-arch portal and the large-scale crossbar windows (windows divided by cross-shaped spars into groups of four windows) in Gothic Revival style stem from the time after 1860, as does the room layout inside. The outbuildings shown in the cadastral plans from 1812 and from 1841 to 1843 have disappeared.
