A plan for an atelier built on the approach to Nakamichi Yasaka Shrine in Osaka. It is also an area where old tenement houses are lined up, and a small section of the area was rebuilt. The building is a bed for eels, with a width of 3m and a depth of 10m.The building was designed to be a wooden structure with no walls on the short sides, and was designed to be a row house that would allow light and wind to reach deep into the building. In the plan, we installed braces raised by high foundations across the floors to ensure flow lines, adjusted the strength of the braces to within 6 meters, and continued to use commercially available wood. In addition, we have created a thoughtful space that is compact but does not feel narrow or dark, using braces to divide the space in the longitudinal direction while arranging each function. The aim was to create a flexible and bright tenement house that would be easy to renovate and update in the future, while simultaneously providing a studio space open to the city and a private home-like environment.
