T is a minimal house located in Toyota, Japan, designed by Katsutoshi Sasaki + Associates. Both the name of the room (function) and the cenesthesia (volume) affect residential architectures. Some are rational but leave the space and living in the rigid and inconvenient relationship. The architects wanted to create the place where the sense of embracement and the laid-back breadth provided by the scale can coexist. For this plan, the designer decomposed the length, breadth and height that make up three-dimensional shapes, and designed the “width” of the room from the human perspective to give the embracing comfort, and the “length and height” from the landscape perspective in light of the streetscape and the premise. The designers used 1.55m as the smallest common denominator and the effective dimension for the width of rooms after the numerous simulation of housing lives. Two cubic capacities of 1.55m in width, 13.5m in depth and 8m in height sit next to each other over the T-shaped structure with the joint pillar/beam.
