架构师提供的文本描述。这是一个内部装修工程，在东京现有的两层木结构房屋，建于大约40年前。客户是一对年轻夫妇，装修前妻子的父母住在那里。客户决定和他们的父母住在这间房子里。不久之后，妻子的祖母也决定一起住在这所房子里，她独自住在远离东京的乡下。因此，客户要求翻修适合容纳4代人的房子-祖母(第一代)、父母(第2代)、客户(第3代)、客户的儿子(第4代)。

Text description provided by the architects. This is an interior renovation project of an existing two-story timber structure house in Tokyo built approximately 40 years ago. The client is a young couple, and the wife’s parents were living there before the renovation. The client decided to live with their parents in this house. Soon after, the wife’s grandmother who lives alone in the countryside – far from Tokyo – also decided to live together in this house. As such, the client requested to renovate the house suitable for accommodating 4 generations - the grandmother (1st generation), parents (2nd generation), the client (3rd generation), the client's son (4th generation).

虽然每个家庭成员的日常行为模式是不同的，但创造一个空间来促进生活在同一屋檐下的各代人之间的联系成为一个主要的焦点。

While the daily behavior patterns of the each family member is different, creating a space to promote connection between all generations living under one roof became a major focus.

此外，我们发现现有的房间被分割成较小的功能，因此，它们既不向外界开放，也不彼此开放，导致日光差和自然通风不良。考虑到这些问题，我们决定改善空间质量、采光和通风也是翻修的关键。

Moreover, we found the existing rooms were split into smaller functions and as such, they were not open to the outside environment nor to each other, leading to poor daylight and natural ventilation. Having these issues in mind, we decided that improving the quality of the space, daylighting and ventilation were also essential to the renovation.

首先，我们仔细研究了私人房间的布置，以充分利用现有的窗户，从而最大限度地利用自然日光和通风。其余的空间被指定为“共享空间”；空间对所有家庭成员开放，并在每一层规划公用设施。私人房间也可以在成员之间交换，以加强几代人之间的交流；类似于一种共享式的生活方式。通过与外界的连接，如将入口空间直接连接到共享空间，以及在共享空间中安装一个大窗口等，有意识地增强了共享空间中共享空间的本质。

Firstly, we carefully studied the arrangement of the private rooms to take full advantage of existing windows thus maximizing natural daylight and ventilation. The remaining spaces were designated as “shared space”; spaces open to all family members and planned in each floor with utilities. The private rooms are also exchangeable among the members so as to enhance communication between generations; similar to a share-house lifestyle. The nature of “share” in the shared spaces was consciously enhanced by making the connection with the outside, such as directly connecting the entrance space to the “shared space” and installing a large window in the “shared space”.

同时，我们亦检讨了现有的架构。虽然柱是按照现有隔墙密集排列的，但我们发现现有的房屋结构不平衡，缺乏必要的结构阻力。因此，我们决定在优化使用现有结构构件的同时，通过支撑梁和结构胶合板增加加固。

At the same time, we also reviewed the existing structure. Although the columns were densely arranged in accordance with the existing partitions, we found that the existing house was structurally unbalanced and lacked the necessary structural resistance. As such, we decided to add reinforcements through supporting beams and structural plywood whilst optimizing the use of its existing structural components.

由于此类研究，一些列被认为是多余的，因此可移除（删除总共20列），从而提供了创建无色谱柱的开放空间的机会。

As a result of such studies, some columns were deemed redundant and thus removable (total 20 columns were removed), providing an opportunity to create open spaces free of columns.

二楼共用空间的天花板呈悬链状，加强了与外界的自然连接，并最大限度地将自然照明扩散到空间中。悬链形天花板轻轻包围了所有4代家庭，他们最终喜欢生活在一个充满自然照明和通风的空间里。

The ceiling of the shared space on the second floor is catenary shaped - enhancing a natural connection to the outside and maximizing the diffusion of the natural lighting into the space. The catenary-shaped ceiling gently envelopes all 4 generations of families who ultimately enjoy living in a space abundant of natural lighting and ventilation.
