该建筑发生在30年前泡沫时期开发的住宅区。虽然这个地区曾经是一个田园诗般的乡村,但在一个开发商将其开发为城市街区的住宅区后,合理地将其划分为被栅栏包围且相互远离的孤立的房屋,已被应用于该地区。此外,由于日本80年代和90年代著名的房屋建筑商的营销策略,使用 “我的家 “的符号来回应同期经济增长带来的日益增长的住房需求,这些房屋被提供了一个倾斜的屋顶。

The construction takes place in a residential zone developed 30 years ago during the bubble period. Although this region used to be an idyllic countryside, following its development by a single developer to residential area as a city block, a rational subdivision into isolated houses surrounded by fences and distant from each other, have been applied to the zone. Additionally, as a result of a house builders’ famous 80’s and 90’s marketing strategy in Japan using the symbol words “My Home” to reply to the increasing housing demand following the economical growth during the same period , these houses were provided a pitched roof.

随着时间的推移,这种城市布局和屋顶形状成为该地区的特征,居民开始保护它,起初,作为每个新建筑或现有建筑改造的规则,然后,最后,在2015年由 “居民协会 “向政府要求将其变成一个地区规划法。

Over time, this urban layout and roof shape became an identity for the zone and dwellers began to protect it, at first, as a rule for every new building or modification of an existing one, then, finally, by turning it to a district plan law demanded to the government in 2015 by the “residents association” .

对于这种情况,我们的立场是认为一个房子可以从这些规则中创造出建筑的意义,为该地区未来的发展提供一个线索。
这些规则的要点被认为是以下几点。
我的家 “的符号导致了一个倾斜的屋顶。
在这种情况下,除了 “我的家 “的标志,很难找到其他令人信服的理由来解释这个形状。我们决定保留最合理但无深度的含义:它是一种让阳光穿过邻近土地的方式。之后,我们用这个形状通过创造一个中央中庭来统一房子的内部空间特征。

Our position regarding this situation is to think a house that would create architectural meaning out of these rules as a way to give a clue for the upcoming development of the area.
The rules points have been thought as following:
The “My Home” symbol resulting as a pitched roof:
In this situation, it is difficult to find another convincing reason to this shape other than the “My Home” symbol. We decided to keep the most reasonable but depthless meaning: it is a way to let sunshine go through to the adjacent land. Afterwards, we used this shape to unify the house’s inside spatial identity through the creation of a central atrium.

外墙与场地边界的距离。
我们注意到现有建筑在高度和占地面积上都有一个规模问题。他们有更多的空间,这导致了被遗弃的房间和与外部的不良关系。为了解决这个问题,我们决定只在一楼保持占地面积的规模,使一楼更小。

The outer wall’s distance to site borders:
We noticed a scale problem for existing constructions both for height and for footprint. They have more space than needed which results in abandoned rooms and a poor relationship to the outside. To solve this problem we decided to keep the footprint scale only on the ground floor, making the 1st floor smaller.

通过这样做,我们创造了一个环绕房子的露台空间。然后,我们将1楼定位为在南侧创造一个大露台的方式。

By doing so, we create a terrace space rounding the house. We then positioned the 1st floor in a way that creates a big terrace on the southern side.

挡土墙。
由于这是一个山坡地,它的发展经历了一个分层,形成了一系列平坦的地块和挡土墙。每个地块的高度遵循相邻地块的1/3-1/2的规则。
 由于挡土墙已经存在,我们选择部分掩埋底层,以解决高度的尺度问题。

Retaining walls:
As it is a hillside site, its development went through a stratification making a series of flat parcels and retaining walls. Height of each parcel follows a rule of 1/3 – 1/2 regarding neighboring parcels.
 As retaining walls already exist, we chose to partially burry the ground floor solving the height’s scale problem.

由于这些操作,房子得到了一个风景优美的屋檐,一个连接内部和外部的浮动平台,以及一个产生通道和停车场的天蓬。按照这个方案,我们能够为现有的规则和法律赋予一些意义,同时为该地区的未来发展创造一个线索。

As a result to these manipulations, the house gets a scenic beautifully shaped gable, a floating terrace connecting interior and exterior and a canopy producing approach and parking. Following this scheme we were able to give some meaning to the existing rules and laws while creating a clue for the future developement of the zone.
