架构师提供的文本描述。这座三层楼的小房子建在一个40平方米的小区里，从主干道走几分钟就到了。这是一个人口密集的地区，有两到三层的小房子，代表着东京的共同生活条件。因此，我们的客户的要求反映了城市居民的共同要求：他们想要“封闭”的居住空间，以保证安全和隐私，但也要“开放和明亮”，里面有充足的自然光线。

Text description provided by the architects. This small three-story house is built on a 40m2 lot located in a residential district, which is a few minutes walk from the main road. It is a densely built- up area with small two- or three- story houses, representing a common living condition in Tokyo. Therefore our client’s request reflected common demands of urban residents: they wanted living space that is ‘closed’ for security and privacy, but also ‘open and bright’ with sufficient natural light inside.

由于有限的预算和适度的生活方式，房子是一个简单的三层的木结构房屋，每层都有不同的功能。建筑物高度和天花板高度由北侧斜线调节自动确定。我们打算在这一小卷书中创造一种空间感。为了最大限度地提高垂直度，我们提供了与底层楼梯相邻的生活/用餐/厨房空间，这样他们就可以从那里体验到音量的全部高度。

Due to limited budget and modest lifestyle, the house is a simple three-story house of wood construction, with each floor accommodating different function. Building height and ceiling heights are automatically determined by north side slant line regulation. We intend to create a sense of spaciousness in this small volume. In order to maximize the verticality we provide living/dining/kitchen space adjacent to stairway on the ground floor, so that they can experience the full height of the volume from there.

通过在工地边界设置混凝土砌块围栏，我们在墙壁和房屋之间建立了半室内区域，从而使室内空间在视觉上延伸到场地的全部范围。我们还想在每一层提供各种照明条件。在底层，整个空间通过半室内区域和楼梯的间接光照射，创造了软和扩散的效果，就像人工照明一样。相反，他们可以享受从二楼和三楼窗户进来的直接自然光。

By placing concrete block fence along the site border we create semi-interior zone between the walls and the house, so that the interior space is visually extended to the full extent of the site. We also want to provide various conditions of light on each floor. On the ground floor the entire space is illuminated with indirect light coming from above through the semi-interior zone and stairway, creating soft and diffused effect like artificial lighting. On the contrary they can enjoy direct natural light coming in from windows on the second and third floors.
