An essential feature of Karl Junker’s work is the equal treatment of architecture and interior architecture. Just like on the outer facades, wood dominates the interior of the rooms.

All walls and ceilings – except for the painted back boards of the stove and oven – have wood paneling. Carved and painted wood ledges were nailed to the walls and ceilings to give them structure. These ledges are complemented by ornamental elements, which are symmetrically arranged and cover the walls like a second skin.

In some areas, the ledges reach far into the rooms – most noticeably in the vestibule where the upper parts of the walls are covered with paintings.
