A house built on a sloping area. The skip-floor spaces were designed to take advantage of the difference in floor levels that follow the existing slope of the land. The ground floor is a space made of the earthen floor and earthen block walls, integrated with the outdoor ground. The upper floor is a three-dimensional one-room space with light shining in from multiple directions. The space made of earthen blocks with moisture control and resource recycling properties was realized in collaboration with the soil material research team.
