Entry Description

Regenerative Vegan House:
Yakushima in southern Japan, with abundant rainfall meets almost 100% of its electricity demand through hydroelectric power.
This building, positioned to harmonize with existing vegetation, rocks and natural spring water, is a regenerative house that not only lets residents feel close to nature but also aims to enrich the natural cycle.
Made from natural, plant-based materials can also be called a "Vegan House," as it is in-tune with the lifestyle of the residents. Its ethical framework that respects life is a concept that redefines the principles of sustainability.
