Tree-ness House

Akihisa Hirata

Savage hierarchical structure

It is a complex building of houses and galleries built in Toshima-ku., Tokyo.In one tree, different parts are organically coexisting, such as trunks, branches, and leaves. Here, as well as those relationship,boxes, pleated windows, are hierarchically combined to create the regions where one tree creates in the air, I tried to create <tangle tab> where ambiguous inner and outer boundaries.


粗曠的層次結構

這是一座建於東京豊島区的住宅和畫廊的綜合建築。在一棵樹上,不同的部分有機地共存,例如樹幹、樹枝和樹葉。在這裡,除了那些關係,盒子,打褶的窗戶,被分層組合以創建一棵樹在空中創建的區域,我試圖創建 <纏繞標記> 模糊的內部和外部邊界。

Box, pleat, plant

The box is an RC structure of room size, considering the mutual relationship of the rooms, stacking up while creating an appropriate overlap, the whole structure including a three-dimensional void is created.

Next, a pleated window is placed in the box. The pleats is made of a single continuous surface with the inner wall and fused with the box by placing concrete by casting factory welded iron plate as a permanent form .


盒子、褶皺與植物

盒子是指一個房間大小的RC結構,考慮到房間的相互關係,堆疊起來,同時創造出適當的重疊,整個結構包括一個三維空間。接下來,一個打褶的窗口被放置在盒子裡。褶皺由與內壁的單一連續表面製成,並通過澆鑄工廠焊接鐵板澆築混凝土作為永久形式與箱體融合。

The space inside and outside is agitated, and a comfortable place of the body scale is generated.

Place the plants around the pleats. With lightweight soil with high water retentivity enclosed in pleats, plants can be maintained only by rainwater. Plants adapted to the microclimate of various places like the mountain vegetation are arranged.


內外空間激盪,產生身體範圍的舒適場所。將植物放在褶皺周圍。將具有高保水性的輕質土壤包裹在褶皺中,植物只須靠雨水來維持。佈置了適應各地小氣候的植物,如山地植被。

Otherness of tangling

Box sets, pleats, plants originally have different characters. However, it seems that combining them in a hierarchical way will create an organic whole. It is a hierarchical structure that can be described as [[plant / pleats] / box].


纏繞的可能性

成群的箱體、褶皺、植物本來就有不同的特點。然而,似乎將它們以層次結構的方式結合起來會創造一個有機的整體。它是一個層次結構,可以描述為[[植物/褶皺]/箱子]

Rather than a self-similar hierarchical structure called a fractal but a "wild hierarchical structure" that can be done by hierarchically learning others who have different characters.

Like waking up the wilds of human, to create an architecture that is highly spatial, lively <tangle tab>.


不是稱為分形的自相似​​層次結構,而是可以通過分層學習具有不同特徵的其他人來完成的“野生層次結構”。就像喚醒人類的荒野,創造一個高度空間化、生動的建築<纏繞標記>

Tree-ness House was realized over 8 years due to the influence of the great earthquake and change of conditions. However, the idea to make a hierarchical structure of others and wild in an architecture proposed for the first time in this project is realized without losing freshness and casts possibilities for future architecture.


由於大地震的影響和條件的變化,樹型屋花了8年多才建造完成。然而,在這個項目中首次提出的架構中,在不失新鮮感的情況下實現了在架構中構建他人和粗曠的層次結構的想法,並為未來的架構帶來了可能性。
