由日本建築師遠藤秀平設計的第二個「泡泡建築（Bubbletecture H）」在位於大阪與廣島之間的一個山間揭開面目，這個與自然完美融合的遊客中心再次展示他一貫提倡的「非組合建築」的空間解構美學。
遠看像幾個巨大的泡泡，近看卻有著鑽石一般的精緻切面，這就是日本建築師遠藤秀平（Shuhei Endo）的最新作品：泡泡遊客中心（Bubbletecture H）。這個坐落在大阪和廣島之間一個山區裡的球體建築，從遠處看恍若飄落在林間的氣泡，從近處看則似從紅土裡伸展出來的岩石，總以一種滿是自然氣息的情狀，吸引過往行人注目。這個形象地表達自然界生態平衡系統的遊客中心，旨在讓來訪者從踏入這個地方時就領悟到環保的重要意義，而這樣的設計是出自建築學或環境科學還是幾何學的靈感呢？反正你能想到的都在裡面。
這個面積968 平方米的「泡泡房子」由三部分組成，一個演講廳（可作劇場），一個會議室，還有一個書店（可作畫廊），三個球體之間貫通連接，彷彿即將匯合的水滴。其中兩個球體建在較為平坦的山路邊，另一個則順著山坡的走勢「懸浮」於地上，所謂「懸浮」是指它並沒有直接打地基建在地面，而是靠16 根直徑1.5 米的混凝土柱子支撐起來，與另兩個球體的水平高度保持一致的同時，又減少對土壤和地貌的破壞。
任何人都會覺得如果「泡泡」的表面換成閃閃發光的玻璃一定會更驚豔，但設計師卻摒棄了這種「山谷珍珠」的效果，用木材和鏽鋼做材料，讓建築與大自然緊密貼合。木材選用日本當地的雪松原木，原木被捆紮成一塊塊的三角形再用鋼架串聯起來，這種材料的應用以及整個建築的球型結構帶來了良好的通風效果，正好彌補了小窗戶的不足，充分考慮到透氧性，同時因為沒有橫樑，令整個空間顯得異常開闊，少了壓抑感，而屋頂的儲水系統可用來收集雨水作灌溉之需，處處皆有環保。建築外壁選用經過處理的鏽鋼（rustedsteel），厚度只有1.2 毫米，卻能抵抗風雨侵蝕。原木牆壁和鏽鋼外殼都是事先在工廠做好，以避免現場施工對周圍環境的影響。鏽鋼的顏色與大自然相當吻合，不顯疏離，在建築外壁的角角落落都看似不經意地種上了苔蘚和草皮，來加強整個建築與自然環境的和諧。
其實Bubbletecture H 還有一個兄弟，那就是遠藤秀平在六年前建的被命名為「泡泡建築」的Bubbletecture M，是現代建築史上很有代表性的作品。非常擅長設計與自然結合的建築的遠藤秀平提倡「非組合性建築」，即建築應該是一個完整的個體，而不應由各種牆體、樑柱等分割成各自獨立的功能區，所以遠藤秀平的作品總是不斷嘗試新的材料，將各種材料融為一體，空間也都沒有生硬的分割，各建築組合構件之間的界限相當模糊，這也是他所定義的「半建築風格（halftecture)」，他也因此而被稱為建築解構主義者。
建築師的話：
The client requested that all people who will visit this place including the inhabitants of Hyogo prefecture, improves the interest for global environmental concerns and be able to experience various approaches as the place of environmental study.
We thought about creating the new environment architectural space that could share the point of contact with nature and environment providing a keyword called 「the circulation」 in a relation with nature for the request.
The site is on the steep slope of the north side in the forest. After integrating all functions that the client requested at the design term into three, required area and volume were set according to the function and structure. The two functions were arranged in parallel on flat land (old town road was there) that had remained at a high level in the site, and another was arranged having floated from the slope at the same level of other two. This is because it is assumed very important to make use of the limited flat land, keep natural landform as large as possible, and to minimize the influence of construction against peripheral natural environment. The form of the building shows the rational shape that connects these three functions for plane and section.
Japanese cypress thinning wood log that is used for superstructure is provided with the intention of realizing the light structure as well as standardizing and improving the work efficiency of the timber using, and to fix the amount of CO2 emission. The weather resistance steel board of 1.2mm thickness is used for outside roof and wall finish. This steel board shows the characteristic that doesn't rust any more after stabilizing process of the initial rust.
Moreover, we tried to green a roof and wall partially applying moss that grows by moisture on an atmospheric inside and turf that grows on the soil containing high retentivity of water.
The material was chosen not only for the characters of the maintenance free or the low maintenance but also of the quality that acquires the form the oneness with a natural spectacle obtaining the expression of architecture that cooperates with the natural environment that changes and grows up.
（From basics to floor）for the structure of under part, 16 Deep Foundations of 1.5m in diameter are adopted, to minimize the influence of the construction against peripheral natural environment. The part of the building that touches the ground is RC structure and composed underground beam, and the part of the building that floating from the ground is SRC structure which used a steel frame together. They are connected and composed footing beam. And the floating part with underground beam is supported by the building frame of RC that is also used as a water tank for fire prevention.（It is the upper part from the floor）For the superstructure, the single-layered three-dimensional truss structure which is made out of Japanese cedar thinning wood log and ready-made hardware covers the space for one body. This truss had been begun to be assemble in every three main building space. On the nearest flat land (a yard), a set of truss which has 2-3 logs with one joint parts and has composed already on the ground was lifted with a crane, and connected by human power. The rooms such as a waiting room or the office which are arranged in the space of the truss constitute are composed with general RC wall-type structure and steel-frame structure.
