半地下的开敞空间未来可作为儿童房使用，客厅、厨房和餐厅位于中间层而属于主人的私密空间则位于顶层。尽管建筑所在的基地狭小而受限，位于入口门厅与厨房空间上方的通高空间将不同的楼层串联起来，使内部空间显得开敞而明亮。此外，内嵌于楼板之中、180毫米厚的LVL单板梁保证了跨度6米的二层楼板无需任何额外的柱子支撑，形成了开阔的无柱空间。

It has a half-basement free space which can be a child room in the future, the living, the kitchen, and the dining room in the middle floor, and the private space in the second floor. In spite of its restricted premise, it makes the residence so spacious by connecting these floors with voids which run through the entrance hall and above the kitchen, respectively. Furthermore, the integrated 180mm-thick LVL beams make 6m of a column-less second floor slab possible.

单一的楼板既为天花，也为地板，尽管简单，但仍极好的传递了材料的结构之美。

With this simultaneous design of the floor and the ceiling by a single slab, though simple it is, one can feel the presence of structural materials.
