这座房子的规划是为了利用锯齿形屋顶和斜面天花板的组合所产生的空间扩展。业主的要求是一个能够珍惜家庭关系的木制单层房屋。规划以3×3的九宫格为基础，将家庭的公共空间设计为中心的一室一厅，而私人房间则分散在四周，旨在实现家庭团结和个人独立的感觉。
This house was planned to make use of the expansion of space created by the combination of a saw-tooth roof and sloped ceilings. The owner’s request was a wooden one-story house that could cherish family ties. The planning is based on a 3×3 nine grid, with the family’s common space designed as a one-room in the center, and the private rooms dispersed around, aiming to achieve both a sense of family unity and individual independence.
在一个占地面积很大的单层建筑中，对中心的自然采光是一个挑战。由于它是一个广阔的地面，不需要担心来自周围高处的目光，所以在锯齿形屋顶上共安装了六个面向南北的三角形夹层窗，在东西方向上排成三行。南侧的窗户可以看到雄伟的四国山脉。
In a one-story building with a large footprint, natural lighting to the center is a challenge. Since it is an expansive ground and there is no need to worry about the eyes from the surrounding high places, a total of six triangular clerestory windows facing north and south are installed on the saw-tooth roofs, which are lined up in three rows in the east-west direction. The south side windows command the magnificent Shikoku Mountains.
倾斜的天花板朝向这些三角窗悬挂，引导自然光透过天花板表面，扩散到房间的深处。在三角窗的室内一侧，安装了内檐，既是照明台，又是设备和存储空间，以阻挡来自外部的直接阳光，并向天花板表面反射，以减少眩光和热量。
The sloped ceilings are hung toward these triangular windows, channeling the natural light to transmit through the ceiling surface and diffuse into the deep part of the room. On the indoor side of the triangular window, inner eaves which serve both as a lighting stand and a space for equipment and storage, are installed to block direct sunlight from the outside and reflect toward the ceiling surface to reduce glare and heat.
室内有两种类型的饰面：公共区域以天然木材为中心，给人以自然的印象，而私人房间则使用类似石膏墙的墙纸，形成柔和的色调。在这两类空间中，由于材料的不同，打算创造出不同的光线质感。对于夜间照明，利用照亮天花板的直立体的间接光来提供合适和足够的照明。这个直立体的设计是通过安排照得很广的宽光和照得很远的窄光，以渐进的方式照亮整个垂直长的天花板表面。
The interior has two types of finishes: a common area with a natural impression centered on natural wood, and private rooms with plastered-wall-like wallpaper that creates soft shades. In the two types of spaces, it was intended to create a difference in the texture of light due to the difference in materials. For night lighting, the indirect light of the upright that illuminates the ceiling is used to provide suitable and sufficient lighting. This upright is designed to illuminate the entire vertically long ceiling surface in a gradual manner, by arranging a wide light that illuminates widely and a narrow light that illuminates a long distance.
建筑的外观是锯齿形屋顶和三角形窗户的标志性表现。屋顶和墙壁上覆盖着相同的镀锌钢板，设备和开口也采用了相似的颜色，形成了具有统一感的巨大外观。到了晚上，从三角窗漏出的光线使房子变得像一个灯笼，照亮了周围的环境。通过不同方向和大小的窗户，不同类型的玻璃，以及不同的天花板饰面和倾斜角度，创造了六个具有不同灯光的空间。我们决定将这所房子命名为 “六个亮化天花板的房子”。
The exterior of the building is an iconic representation of the saw-tooth roof and triangular windows. The roof and walls are covered with the same galvalume steel plate, and the equipment and openings are also in similar colors to create a massive appearance with a sense of unity. At night, the light leaking from the triangular window transforms the house like a lantern that illuminates the surroundings. Six spaces with different lights were created, by different directions and sizes of windows, types of glass, and different ceiling finishes and tilt angles. We decided to name this house “House of Six Lightened Ceilings”.
