Utter Inn
Västerås Municipality, Sweden · built 2016
Utter Inn (Swedish) or in English, Otter Inn, is an art project by Mikael Genberg that offers underwater accommodation to the public. The facility is entered through a small, typical-appearing Swedish house on the surface of the water. The only representation of this concept is, at this point, in Lake Mälaren near the town of Västerås in Sweden.
