Johann Michael Bossard (1874–1950) was a Swiss-born artist who spent most of his career teaching in Hamburg. Between 1911 and 1950, in the countryside south of the city, he and his wife Jutta created a strange home/studio/work of art they called the Kunststätte, which is probably best translated by a trendy word like "artspace."
Overall view. The building behind the house in the Kunsttempel, the Temple of Art.
And what a weird space it is.
The sculpture garden. Of all the ways to be remembered after you die, creating a really bizarre house strikes me as one of the most interesting and least harmful.
