Anders Berensson Architects has designed a shed that can fold out to become a sauna when needed. The sauna is to be located in a small allotment garden area close to the city center of Stockholm. The local plan allow a complementary storage building of 3 square meter without needing to apply for a building permit. The client however wanted a sauna rather than a storage and asked us if it was possible to design a storage building that could transform into a bigger sauna when needed. The answer to this unusual request became this fold-out sauna. Fold-Out Sauna when closed is a three square meter shed with racks for tools and with an outdoor bench on the back side. Fold-Out Sauna when opened is a six square meters sauna. The racks has become three levels of seating with a view towards the canal from the top seat. The outdoor bench works as a support for the leaning structure.
