Between 2015 and 2020, the new National Park Centre (NLPZ) in the Black Forest National Park was built at the Ruhestein (Baden-Württemberg, Germany) 915 m above sea level. Amid the typical silver fir forests of the region, a total of eight pipe-like boxes up to 65 m long form the unique shape of the building on a slope that are reminiscent of fallen trees lying on top of each other.

Parts of the complex supporting structure are deliberately visible, such as the BauBuche diagonal trusses, which were produced at the HASSLACHER Group's site in Kleinheubach. The connections of the BauBuche diagonals to the upper and lower girders were made with slotted steel plates and bar dowels. Due to the building's location in earthquake zone 1, the supporting structure was made of BauBuche with an opposing arrangement of steel tension diagonals for bracing at the particularly highly stressed points, to be less susceptible to the effects of earthquakes.

The visual highlight of the National Park Centre is the so-called "Skywalk", a non-roofed footbridge that connects the visitor centre with the sloping 35 m high observation tower that offers visitors a spectacular view of the Murg Valley below.
