This floating house is located 1 km from Krasnosilka, Odes'ka Oblast (Ukraine).

"This building is a part of a potato sorting station. That metal bottom
cones used for loading potatoes into trucks. Usually it looks like this.
It's a common construction in agricultural regions of Ukraine,
but this one looks like misplaced or partly dismantled."
