It is a plant-based food complex that brings together a curry restaurant, a bistro, and a donut shop in one location within a commercial facility in Tokyo. The three stores are operated by TOYOKE, a company that develops vegan food and plans and operates sauna facilities to promote people’s wellness. Three different stores and a central kitchen are integrated into a small 43㎡ space. Despite the limited space, the kitchen is equipped with specifications to supply meals not only to the three stores but also to other group facilities. Taking advantage of the space’s location with two facades, one side was planned as a take-away counter for a donut shop, and the other as a curry restaurant and bistro that would be switched between lunch time and dinner time.
We used tile and glass as the main materials. The color of the tiles and the processing and installation methods were changed for each store. This gives a sense of unity to the design while at the same time making them appear to be separate stores. Inspired by the concept of the restaurant, which pursues the possibilities of vegetarian cuisine by cooking vegetables in various ways, we aimed to create a design that shows a variety of expressions with limited materials. As the curry restaurant and the bistro switch between day and night, we proposed the installation of a lighting system that can adjust color and brightness wirelessly to change the atmosphere of each restaurant. By installing this system, we were able to reduce not only the number of lights, but also their power consumption. In addition, we adjusted the design to use tiles in their original dimensions as much as possible. Thereby we have minimized the amount of tile cutting and the waste of building materials.
