Palais Thermal, the thermal spring facilities are an important element of the touristic health and recreation resort at Bad Wildbad, Black Forest Germany. The complex mostly consists of a historic bath, an inoperative terraced sanatorium, a bath hotel with a spa plaza, and surrounding administration buildings. To complement the offer, large outdoor spaces on the second and third floor of the inoperative sanatorium were activated and rebuilt for the use of the spa area. The new atmospheric wooden landscape with outdoor pool, terraces, saunas, and additional facilities offer an attractive outlook to the valley. Over open staircases and an enlarged elevator, the new spaces are developed from the courtyard of the historic building. To prevent views from the neighboring hotel building, a translucent and white membrane spans over the north area. It frames the outlook to the south and east and is also a shelter shield for most parts of the wooden terraces.
