I was requested, after winning through the competition, to design a facility accompanied to the museum of Hiroshi SENJU, a world-famous Japanese painter/artist. Before I started the actual planning, I prioritized building my conceptual work first ( i.e. geometrical shape containing both traditional and modern forms ) in order to make my design coexist on the same site with the museum that had a curved form interpreting Karuizawa ’s nature in a elegant way. I built the design concept form Japanese art culture in order to create an architecture suited to the museum having art pieces appraised internationally.
Such Japanese craft as ‘Origami’, ‘ Sensu fan ‘, or ‘Byobu screen ‘ are created from just one piece of paper, having an infinite possibility to be shaped in various forms. They also have similarity to western geometric design, which are even led to modern art with their originality and beauty. I, at the same time, thought my design coexist with sharp lines of mountainous scenery seen in this area such as Yatsugatake or Asamayama mountains, which is totally contrastive with the curved lines of the museum.
Another important factor I kept in mind as a theme was that my architecture had to work as a landmark where people might encounter artworks, not only as a facility next to the museum. I aimed my design to born infinite possibility with the museum that have totally different elements from my design, just as one piece of paper could be shaped to any possible forms by human hands.
Integration to Surroundings:
The traditional element of Japan like origami and the artist’s modern side were harmonized with the line of a sharp ridgeline like Mt. Yatsugatake and Asama-yama of Japanese famous mountains which wraps in a site, and designed the new architectural type in response to environment. The construction which imitates a sharp ridgeline and consists of geometrical forms like origami is realized in the form where both the heterogeneous things of a straight line and a curve face nature, contrasted with the art museum which united with nature of the author who is a Japanese-style painter itself. The shade of the light with which it is reflected to the wall and roof of the titanium zinc alloy variously bent from the ground while the glass with which the facade of the architecture built in Nature inclined in all the directions reflects the surrounding green responds to the surrounding mountain range.
Sustainable or green features:
It is constituting construction from a sharp straight line in contrast with the art museum which consisted of loose curves, and melts into the mountain range of Karuizawa which spreads around, and the form of construction itself serves as a scene and makes it conscious of the green of a mountain. Not simply to visualize the green, make it consious of the natural way of architecture in this beautiful landscape. It is studied the form of the design suitable for the scene of Karuizawa, conducting structural analysis with constituting a form from a structural frame which make a triangle in how to construct the steel frame which is the frame form of the building so that there may be no concentration of excessive stress, in order to build the sustainable architecture in response to the environment.
In quake-prone Japan, earthquake resistance is always searched for. As for operating a form, a burden is placed so much on construction, and a risk follows. Only modeling was merely designed and the weak construction which does not have the sense of unity was not built, but it is finding out new discovery of the structure in response to environment, and pulled out a construction possibility to the maximum. Furthermore, by using outstanding building materials, the enforcement which pulls out the form to the maximum is attained, and regards construction as the ability to have lived together to environment. Energy saving was considered by using the motion sensor in a multiple-purpose toilet, and reduce power consumption by adopting a high efficiency LED lamp of long-life as the general illumination of a building.
List of major materials and their usage: Titanium, Glass
Taking advantage of the corrosion resistance and durability which was excellent in the titanium zinc alloy by using it for a wall and a roof material, the film of thin rust is generated to the construction exterior, and it serves as a protection film strongly stuck on foundation, and protects a building from corrosion. Moreover, its attention was paid also to the color tone of the “patina layer” which is the visual feature of a titanium zinc alloy.
The patina layer of a titanium zinc alloy is thickness, and since it is the protection film strongly stuck on foundation, it becomes a strong barrier (passivity film) between outside environments. Even if salts, such as acid, alkali, a sea salt particle, or a physical impact breaks, since this patina layer is newly generated from foundation, it can be said to be semipermanent. And a color tone changes further through long time, and a patina layer increases composure and dignity. Melting into the scene around Karuizawa, the color tone which changes deeply and dully ages in “Wabi and Sabi”(austere refinement and quiet simplicity) which is sense of beauty in Japan, and the building which change over the years increase the depth.
The average yearly temperature of Karuizawa is the lowness of 7.9 degrees which is the cold district average. Since it is in the altitude of around about 1000 m, the cold of winter is the climate of the typical highland summer resort type that it is cool in summer. Therefore, the argon gas which is safe gas is poured in that double-glazed glass with high insulation efficiency is adopted, and it is harder to convey heat than dry air. Compared with dry air, argon gas is called safe gas that it is hard to convey heat about 1.5 times. Argon gas is gas which exists also in the air, and it is gas to the extent that it exists more mostly than carbon dioxide in the air.Location: Karuizawa, Nagano-ken, Japan Architect: Yasui hideo atelier, Inc.
