Building No. 8 (Unknown - 1907)
[Store facade of Building No. 8]

The front construction drawing (hereinafter referred to as the elevation drawing) of Building No. 8, designed by Katsuya Yasuoka, who served as the director of Marunouchi Architects after Tatsuzo Sone left the company, features an eye-catching irregular window design. Why is this one different from the others?
The "Building No. 8911 First Floor Plan (hereafter referred to as the Plan)" shows it as a dotted opening, not as a fixture. Looking at the elevation again, it doesn't look like it would be possible to approach directly from Nakadori. It also seems like the opening is too wide for a brick structure. Is this elevation one of the plans under consideration?
It finally became clear when I looked at the detailed drawings. The floor plan shows a display shelf, the plan shows a combination of I-beams, and the waist-high wall is planned to have windows to let light into the basement. These windows would have been show windows on Nakadori Street in the Meiji period. Furthermore, the dotted lines of the openings on the floor plan lead one to imagine that facade of the first floor of Building No. 8 was designed to suit the wishes of the prospective tenants.
What did Chuotei, a French restaurant that was the tenant at the time, display in this large display window?
