 Originally built in 1843-1844, Das Haus and the Einhaus (a house-barn, where humans and livestock live under one roof, a tactic that provided heat from the animals to benefit the humans in winter) are among the last remaining forms of this type of building.The Einhaus is an example of Prussian-style fachwerk, which employs clay and straw filler in hand hewn timber squares; a remnant of the filler is on display in the Einhaus.Das Haus was primarily constructed of logs.
