隅っこや端っこといった用途をもたない空間、へりや段差といった異なる機能の境界は、人が無意識に「居心地がよい空間」と感じる何かが存在する。窓際でまどろむ、段差に座るなどの何気ない動作を誘発し、しばらくその場所に留まりたいと思わせるのである。
人間行動学の観点では、「動作」が集まり意識的におこなうことを「行為」、意識的または無意識的に身体を動かすことを「行動」と位置付けている。例えば、「縁側で本を読む」際には、本を読むという「行為」が、時間の経過とともに風や陽の移ろいを身体で感じることで無意識に身体を動かす「行動」へと変わっていく。内と外との境界、機能と機能の境界は、意識と無意識の動作が混在する人間の本能的な「行動を誘発する場所」であり、それこそが「居心地」をつくっているのではないか。
施主は、夜勤のある消防士の夫、早番遅番のある保育士の妻と子供1人である。各々の居場所が生まれ、互いの営みが重なり合うような「行動を誘発する場所」を随所に設けることで、生活リズムが異なる家族が居心地よく暮らせるようになると考えた。機能の境界を意識動作を促す「行為領域（水色）」、その両側の空間を無意識動作と意識動作が混在かつ連続的となる「行動領域（緑色）」と位置付けた。適度な「距離感」を生み出す仕掛けとして、床と天井の「幅と高さの差尺」を変える操作を行っている。「境界を空間化」することで、意識と無意識の動作が波紋のように呼応し合い、家族が繋がる住宅を目指した。（伊藤孝紀）
A house that spatializes the boundary where individual activities overlap
Spaces with no purpose, such as corners and edges, and boundaries between different functions, such as gaps and steps, have something people unconsciously perceive as a “comfortable space. They induce casual actions such as slumbering by a window or sitting on a step, making people want to stay there for a while.
From the perspective of human behavior studies, “action” is defined as a conscious act of gathering together, and “behavior” is defined as conscious or unconscious movement of the body. For example, when “reading a book on the porch,” the “action” of reading a book is transformed into an “action” of unconsciously moving the body as the body feels the wind and the sun changes with time. The boundary between inside and outside, between function and function, is a “place that triggers action” instinctively in humans, where conscious and unconscious actions are mixed, and this is what creates “comfort.
The client is a firefighter husband who works the night shift, a daycare worker wife who works the early and late shifts, and a child. We thought that families with different life rhythms would be able to live comfortably by creating “action-inducing places” throughout the house where each person has a place to be and where their activities overlap with each other. The boundary of the function was positioned as the “action area (light blue),” which encourages conscious movement, and the space on both sides as the “action area (green),” where unconscious and conscious movements are mixed and continuous. As a mechanism for creating an appropriate sense of distance, the “scale of difference in width and height” between the floor and ceiling has been changed. By “spatializing the boundary,” the conscious and unconscious actions respond to each other like ripples, aiming to create a house that connects the family. (Takanori Ito)
