Living willow architecture
More arboreal architectural awesomeness, here brought to you by German architect Marcel Kalberer and the Sanfte Strukturen group. The first structure, called the Auerworld Palace, was constructed in 1998, in Aeurstedt, Germany, and was their first “willow palace” project, taking the efforts of 300 volunteers to build. Kalberer has gone on to… er… plant 70 living structures.
