This fairytale-like house called "Dragspelhuset" is an extension to an original cabin dating from the late 1800s, located on the shore of the lake Övre Gla, in the nature reserve of Glaskogen in Sweden.
Due to building regulations, construction is not allowed along the lake shore, yet, exceptions are made when it comes to an extension of an already existing building.
Build by 24H-architecture, the extension to the cabin has been made to evolve, as the building can literally adjust itself to its environment depending on weather conditions, seasons or the number of occupants.
The extension unfurls itself like a butterfly. During the winter it’s a cocoon, compact with a double skin, as the back of the cabin is pulled in to protect against the cold. During the summer it acts like a butterfly, unfolding its wings for extra shelter during rainy days. The windows of the cabin’s head can open wide and on the cantilever of the moving part one can sit above the strew.
