架构师提供的文本描述。天空花园大厦是东京市中心的两家住宅.设计的主要目的是创造一种环境，使两个家庭可以自由和频繁地互动，同时给每个家庭提供彼此以及外部的高度隐私。建筑规范(特别是建筑与土地比率)所规定的特殊位置和限制，对实现这一目标提出了相当大的挑战。

Text description provided by the architects. Sky Garden House is a two-family residence in central Tokyo. The main goal in design was to create an environment where two families can interact freely and frequently, while giving each family a high level of privacy from each other as well as from outside. The peculiar nature of the location and limitations imposed by the building codes (in particular, the building-to-land ratio) presented considerable challenges in meeting this goal.

这座房子是在陡峭的斜坡上建造的，其中客户和他们的两个孩子住在前两层，他们的父母住在三楼，地势的高低相差约5米，使得一楼的一部分有效地转入地下。

The house, where Clients and their two children occupy the first two floors and their parents live on the third floor, is built on a steep incline, with about 5 meters in height difference between the low and high points of the land, rendering part of the first floor effectively underground.

建筑与土地的比例要求最大限度地利用现有的空间，为两个家庭提供开放、舒适的居住空间。我们和客户试图通过一系列延伸的讨论来应对这些挑战，这个过程与试图拼凑一个复杂的谜题没有什么不同。

The building-to-land ratio required that maximum use of the available space be made to secure open, comfortable living space for two families. We and Clients sought to address these challenges through a series of extended discussions, in a process not unlike trying to piece together a complex puzzle.

最后，我们决定了三个设计特性来迎接这些挑战。首先，我们设计了一个光环，让每个房间都面对它。这有两个好处。其一，这将确保前三层的每个房间都能得到充足的阳光。另一个是，它将创造一个开放和宽敞的感觉，房子，同时允许隐私从外部环境。

In the end, we decided on three design features in meeting these challenges. First, we designed a lightwell and had each room face it. This had two benefits. One was that this would ensure that each room on the first three floors would receive good amount of sunlight. The other was that it would create an open and spacious feel to the house while allowing for privacy from outside environs.
