We designed SACHI HOUSE, a medical welfare facility, resembling the feeling of being at "home". This was to try and bring the right of dignity back to the patients' life, encouraging hospitalized patients, their families, and friends to come together. At the same time, this environment is also designed for nurses to be able to relax. To protect the well-being of both hospitalized patients and nurses, we created this architecture like a two-family house. In addition, by constructing a space according to the site of a triangle and using local thinned wood, we confront the forestry loss issues that currently affect whole Japan, as a thoroughly eco-friendly and authentic architecture, built as if it is situated in a forest.
