Dragspelhuset At Övre Gla by 24h Architecture (Glaskogen nature reserve, Sweden) "A retractable extension to a cabin from the 1800s. During the summer, it can be lengthened out from the original structure. During the winter the cabin is a cocoon, compact with a double skin against the cold. Its walls are covered in reindeer hides, turning the living area into a sensuous fur cave."
