OH8 Office is a minimalist office located in Sapporo, Japan, designed by Takaomi Yoshimoto + Associates. The plan was to utilize as much of the existing structure as possible, while simultaneously improving the heating and insulation of the space at low cost. The space consists of a row of windows that provide abundant natural lighting within the space. In addition, light concrete was used as flooring throughout, and reflects the lighting to provide additional illumination.
