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

The front construction drawing (hereafter referred to as the elevation drawing) of Building No. 8, designed by Yasuoka Katsuya, who served as director of Marunouchi Architects after Sone Tatsuzo 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 seem like it would be possible to approach it directly from Nakadori Street. The opening also seems 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 beams made of I-beams, and windows are planned in the waist-high wall to let light into the basement. These windows would have served as show windows on Nakadori Street during the Meiji period. Furthermore, the dotted lines showing the openings on the floor plan suggest 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), the tenant at the time, display in this large display window?
