Overview
02 Process
The blocks serve as structure, finish, and seating, and slit windows can be opened and closed to adjust airflow. Indirect lighting was built into the central column of the stairs in collaboration with a lighting designer.
A two-story timber sauna with a total floor area of 23.16 m² and a maximum height of 6,210 mm, completed in November 2022.
ブロックは構造材・仕上げ材・座面を兼ね、スリット窓の開閉で空気の流れを調整できる。照明デザイナーと協働し、階段中央の柱に間接照明を組み込んだ。
木造2階建て、延床面積23.16㎡、最高高さ6,210mmのサウナ施設で、2022年11月に竣工した。
The curved cypress blocks were all machined three-dimensionally with a 5-axis CNC, and each has a different shape. They were stacked on site to form a freeform surface, reconstructing ancient stacked construction with digital technology. Each block has three-dimensional grooves and is screwed horizontally and vertically to prevent slipping.
Five-axis machining of the timber was done by Artistry and three-axis machining by Ohira Sangyo, with construction by Hatanaka Sangyo and VUILD.
曲線を描くヒノキのブロックはすべて5軸CNCで三次元加工し、形状はすべて異なる。現地で積層して自由曲面を構成し、古代建築の積層構法をデジタル技術で再構成した。各ブロックには立体的な溝を設け、水平・垂直方向にビスで固定してずれを防いでいる。
木部の5軸加工はアーティストリー、3軸加工は大平産業が担い、施工は畑中産業とVUILDが行った。
Structural design was by yasuhirokaneda STRUCTURE and lighting design by TILe.
構造設計はyasuhirokaneda STRUCTURE、照明計画はTILeが担当した。
