项目基地面积仅有42平米，建筑师在面向公园的一侧设计了三层水平向凸窗，在不占用建筑面积的情况下为室内带来了充足的采光，住户也可以透过窗户欣赏绽放的樱花，尽享开放的空间感觉。

On a site area of only 42m2, we planned a housing with a horizontally long bay window (not included in the floor area) towards a park where you can see cherry blossoms. Three layers of bay windows were set up to take in the scenery and light inside the building and it became a building that feels open.

凸窗不仅可以被用作工作桌和餐椅，它还可以形成屋檐，夏季遮阳，冬季将阳光引入房间深处，使混凝土地板变得更加温暖。

Besides being able to effectively utilize the space by using the bay windows as a work desk and dining bench, it also functions as an eaves, making shadows in summer and delivering sunlight to the back in winter and warming the concrete floor.

在凸窗下部设有可以开启的小窗，即使在下雨的时候也可以打开通风。住户也可以通过这些窗户浇灌凸窗间的花朵。

At the lower part of the bay window, small windows can be provided to obtain constant ventilation even on a rainy day. It is also used to water the flowers between bay windows.

此外，窗户上下的墙面还可以作为悬臂梁起到结构作用，以保证不设竖向框架，将春樱和秋叶不加任何阻拦地带入各个楼层。

In addition, the hanging walls and waist walls at the upper and lower sides of the bay window function structurally as cantilevered beams, ensuring a frameless opening for capturing outdoor environments such as cherry blossoms and autumn leaves on all floors.
