In April of 2015, AHO Team from The Oslo School of Architecture and Design was awarded the first prize in an architectural competition hosted by the LIXIL JS Foundation. The theme of the competition was ‘House for Enjoying the Harsh Cold’. The outcome, The Inverted House, is a small guesthouse retreat, a kind of ur hut, in the wilderness of the Japanese island of Hokkaido.

The Inverted House brings the harshness of the winter environment of Hokkaido into the house by minimalizing the heated interior and creating a series of interconnected sheltered exterior spaces with various architectonic and micro-climatic qualities, with varying distance to nature, created by floor heights and roof slopes.
