The beauty salon “ONE & ONLY,” which is a renovated machiya in Kyoto, opened in June 2020. Since this is a traditional Japanese townhouse, it was old and needed repairs. The owner's request was to keep the original feeling of the machiya so that it fits in with the streets of Kyoto. He wanted us to express a space with more newness. "What is the charm of machiya?" "What is Kyoto-like?" I think that the word "Okuyukasa" in Japanese culture had a great influence on it. ("Okuyukai" in Japanese culture means "what you want to know more is elegant and beautiful." It is a word that expresses "the state of depth and elegance." ). The theme of this design is "a graceful salon.” It's like taking a deep breath in nature while blending in with tradition and the city. We wanted it to be a hair salon where you could calm down. Therefore, we selected "leave," "lose," and "add" for each part. The charm of this machiya that should be left was the traditional structure and the tsubo-niwa. This tsubo garden is the farthest from the entrance, so no one could see it. There is a reason for this, and there is a theory that the tsubo-niwa was created to prevent light and wind from entering the interior of the machiya in Kyoto because the façade is narrow and the depth is long. In this way, a part of the outer wall is hollowed out to make a large round window, and the partition material inside the store is changed to one piece of glass so that many people can see the beautiful tradition with "the ingenuity of the ancestors." By doing so, I was able to see from the outside to the innermost part of the tsubo garden. In addition, this round window is equipped with a "lattice" that blends in with the scenery of Kyoto. By widening the grid pitch more than usual, it becomes a window grid that is easy to see from the outside. During the daytime, you can feel the nature by inserting the sun and shadows into the store depending on the season. And at night, on the contrary, the light leaks out, so it illuminates the quiet streets of the city like a full moon as a crime prevention role. Also, I put a bench on the approach from the entrance to the reception. It’s a place where you can communicate with the people of the town. There is a reception to extend the entrance, a cut on the left side, and shampoo on the right side when you go up to the store, and there are also separate spaces with a sense of distance. Two types of wall materials were used when roughly classified. One is a soil wall where the wall itself breathes and regulates humidity. This soil wall used a color close to pink to express a warm atmosphere. The other is Chinese wood. I wanted you to feel the warmth of natural materials by using bright wood so as not to interfere with the treatment. And although the floor was originally tatami, it was changed to tile to satisfy the function as a salon. The material of the door has been changed between the floors of the shampoo space, but the traditional structure remains the same. It became a space where seasonal flowers were displayed. If you go deeper from there, you will see the entire tsubo garden that you can see from the front. I wanted to cut out this scenery, which can only be seen by visitors, like a Japanese painting. Trees were used on the porch of this garden, but due to the progress of corrosion, the material has been changed to long-life tiles and stainless steel in consideration of durability and design. As a result, the light from the outside was reflected, and the inside of the store was projected more beautifully. The flow line and visibility area are calculated so that the owner who runs alone can always see the entire store. We also considered the environment by adding efforts from a new era, such as making it possible to reduce power consumption by taking in natural light from large round windows and tsubo gardens, and changing to materials that have a long life and are not easily discarded. There is a pleasant contrast caused by adding materials, colors and shapes that were not often used in Japan at that time to traditional ones.
