架构师提供的文本描述。这个狭窄的地方位于大阪的中心，周围是一些公寓楼的后部。客户想要从房子里看到Yodo河，还有一个屋顶露台，可以在YodoRiver上享受一年一度的烟火比赛。

Text description provided by the architects. The narrow site is located at the heart of Osaka, surrounded by the back of some apartment houses. The client wants to have a view towards the Yodo River from the house, as well as having a rooftop terrace for enjoying the annual firework competition above Yodo River.

我们不是简单地在往YodoRiver的方向上开洞，而是把从地面到二楼的小窗户螺旋式地展示出来，就好像它们在旋转。这种洞口的布置，特别是对河流、街道和天空的视野形成了框架。通过将内部与奇妙的景观连接起来，生活空间的体积也会在视觉上扩展。我们决定使用小窗户，而不是在海拔中心安装大窗户，因为它将在城市环境中为家庭提供自由感和隐私需求之间的平衡。

Instead of simply putting openings on the direction to Yodo River, we displayed the small windows from the ground to second floor spirally, as if they were swirling. This arrangement of openings frames the view in particular to the river, the street and the sky. By connecting the interior with the fantastic view, the volume of the living space also expands visually. We decided to use small windows rather than installing big windows in the center of the elevation, because it will provide a balance between the sense of freedom and the need of privacy for the households in its urban context.

在建筑方面，灰泥被涂在墙壁上，墙壁变成了表面，没有缝，只有腰带。这使我们可以自由地把窗户放在表面。此外，由于窗户的螺旋显示，无法在单一平面上建造承重墙，因此我们采用了钢框架来支撑，并设法实现了一种螺旋形式的承重墙。另外，每个板上的开口都是三角形的，采用Hiuchi梁-梁是斜向的.这些三角形切割板形成一个流体螺旋体积的内部循环，从地面到露台。虽然这是一个微小的几何变化，它创造了一个流动的内部和外部的建筑，这表明了复杂的关系复杂的上下文。

In terms of construction, the plaster is applied on the walls, which become surfaces without joints but sashes. This allows us to place the windows freely on the surface. Besides, it was not possible to build a bearing wall on single flat surface due to the spiral display of the windows, so we used a steel frame to support and managed to realize a spiral form of bearing walls. Also, the opening on each slab is triangular via using Hiuchi-beam a beam spans diagonally. These triangular cuts on the slab form a fluid spiral volume for the circulation internally, from the ground to the terrace. Although it’s a minor geometry change, it creates a flow for both the interior and the exterior of the building, which shows a sophisticated relation with the complicated context.
