This is a project by Endo Shuhei Architect Institute and it is located at Hyogo, Japan. There are ten images for Bubbletecture H.
The site is located in west of Hyogo Prefecture and in the north end of the Harima Science Garden City where four towns, Kamigori, Tatsuno, Shingu, and Sayo are adjacent. The site is in the sudden hillside of the north side in the forest, and exists in the naturally rich. In the plan as the place of environmental study, the client requested that all people who will visit this place including the inhabitants of the Hyogo prefecture improved the concern for global environmental concerns and be able to experience various approaches. We materialized this place as a new environmental architectural space that be able to share the point of contact with nature.
We put together main function that the client requested at the design term to the three of it, the two were arranged in flat place part (old town road) that had remained at a high level in the site in parallel, and another was arranged while matching the level of other two and having floated from the slope. A floating part is supported from the slope with the building frame of RC that combines the fire prevention water tank by using 16 Deep Foundations of 1.5m in diameter for the base. According to adopting that way, we can make use of the limited flat place, keep as large as natural landform and control the influence against peripheral natural environment at the construction stage to the minimum.
The superstructure formed the roof and the wall with the single-layer truss structure used Japanese cedar thinning wood log of Hyogo prefecture (chiefly 150mm in the diameter) and ready-made hardwares, and achieved a consecutive three solid dimension space. The shape is sets the needed space volume of each function by the function and the structure, and reasonable shape connected plane and section. The courtyard located in the center of gravity on the plane is the function as an optical garden where light is taken internally and plays the role to increase the stabilization of the structure.
The single-layer truss structure with this thinning wood is a technology that aims at lightening construction and makes standardization and the work efficiency improvement of the wood using, and CO2 fixed.
The weather resistance steel board of 1.2mm in thickness is used for an outside roof and the wall finish material. This steel board stabilizes initial rust and shows the characteristic that doesn't rust any more. Moreover, we tried to green a partial roof and wall by moss that grows by moisture on an atmospheric inside and turf with high water retentivity soil. These materials that change the expression by the time passage acquire not only maintenance free and the low maintenance but the expression of architecture that cooperates with the natural environment that changes and grows up, and form the oneness with a natural spectacle.
In this plan, we proposed various proposals and practiced in the relation of nature by using the key word "Circulation", from the design to construction and management.
We planned ”Bubbletecture H” as a place that the man can experience the story of the big circulation that nature possessed.
