楼梯住宅，东京 / nendo

该项目位于东京的一个安静的住宅区，容纳了两户家庭。由于周围分布的房屋和公寓楼的紧密环绕，该建筑的体量被推至场地北部，并通过大面积的南向玻璃立面来引入阳光、微风和庭院里的绿意。

A two-family home in a quiet residential area of Tokyo. With other houses and apartment buildings pressing around the site, the architectural volume was pushed to the north to take in daylight, ventilation, and greenery of the yard into the living environment by a large glass front southern facade.

房屋的平面布局使几代人精心呵护的柿子树得以保留。考虑到上下楼梯时可能存在的困难，老年夫妇的房间被设置在一层，这样一来，他们养的八只猫就可以自由地在室内外漫步，母亲也可以尽情享受园艺的爱好。年轻夫妇和他们的孩子居住在二层和三层。

The layout plan made it possible to preserve the existing persimmon tree beloved by the previous generations. Considering the potential difficulties of going up and down the stairs, the rooms for the older couple were arranged on the 1st floor. The eight cats living with the older couple roam in and outdoors more freely, and encourages the mother to enjoy her hobby of gardening more freely. The younger couple and their child reside on the 2nd and 3rd floors.

为了避免使两个家庭完全隔离开来，南部的庭院设计了一个类似于楼梯的结构，由下至上贯穿了一层到三层的空间。“楼梯”的内部容纳了浴室和实际的楼梯，其上半部分形成一个半室外的、种满绿植的玻璃房，此外还有日照充足的平台可供猫咪享受攀爬的乐趣。沿对角线分布的这一系列空间让三代人可以在同一屋檐下舒适地共处。

To avoidthe two households being completely separated at the top and bottom, a “stairway-like” structure was designed in the south yard, continuing upward into the building and penetrating the 1st through 3rd floors. Enclosed inside the “stairway” are functional elements, such as bathrooms and a staircase for actual use, with the upper part taking on the look of a semi-outdoor greenhouse with abundant greenery as well as a sun-soaked perch for the cats to enjoy climbing. And so, a stairway and greenery gently connected the upper and lower floors along a diagonal line, creating a space where all three generations could take comfort in each other’s subtle presence.

除了将室内空间连接至庭院，以及联系两个家庭之外，这座“楼梯”还试图融入周围的环境和城市：在街道层，它与南向的道路相连；在屋顶层，则通过天窗与蓝天相接。

Not only does the stairway connect the interior to the yard, or bond one household to another, this structure aims to expand further out to join the environs and the city －connecting the road that extends southward on the ground level, and out into skylight through the toplight.
