架构师提供的文本描述。这个想法只是为了在其有限的网站中创造一个最大的空间。通过尽量减少使用墙壁作为隔断的主要区域，这样我们就可以提供最大的开放空间。印尼城市小型住宅的垂直分区活动大多将服务区放在一楼，起居室-二楼和三楼为卧室。

Text description provided by the architects. The Idea is simply to create a maximum space within its limited site. By minimising the use of wall as a partition toward the main area, so we can deliver maximum open space. Mostly the vertical zoning activities in Indonesia urban small house put the service area on the first floor, living room-dining room on 2nd floor and 3rd floor is for bedrooms.

但是当我开始绘制分区图的时候，我发现一楼实际上是主要活动进行的最舒适的层次。从业主的移动通道和前院的潜在视野来看，一楼有一些我们在上层无法拥有的优势。所以我决定把主区放在一楼，服务区放在三楼/顶楼。在设计客厅用餐区的时候，我意识到，这个10米宽的场地，通过将卧室水平挂在屋顶地板的主梁上，沿着场地的宽度展开，是有可能有一个没有立柱的干净空间的。

But when I started the zoning diagram, in this site I found that the first floor is actually the most comfortable level in which main activities took place. In terms of owner’s mobility access and potential view from the front yard, the first floor has some advantages that we can’t have on the upper floors. So I decided to switch the composition by placing the main area on the first floor and service area on the 3rd floor/ roof floor. When designing the section of living-dining area, I realized that this site which has 10 metre width is possible to have a clean space without column by hanging the bedroom level to the main beam on the roof floor that be spread out along the site’s width.

因此，我用钢结构来建造这座房子的主体结构。整个主体结构在现场施工前已在车间上进行了初步组装，以保证所有钢节点细节的设计和完善。需要的大尺寸梁给了我一个机会来优化横梁的高度，在每个横梁之间放置通风架。这些通风为热风提供循环，在建筑物左右两侧有屋顶玻璃，白天为房屋带来自然光。

Therefore I use the steel structure to build the main structure of this house. The entire main structure has been preliminary assembled on the workshop before it’s been constructed on the site, to ensure all the steel joint detail were design and worked perfectly. Large dimension beams that been required gave me a chance to optimize the height of the beams to place ventilation grill between each of it. Those ventilations provide circulation for hot air to flow out with roof glass at the left and right side of the building to bring natural light for the house during the day.

二楼，所有卧室都被放置在楼梯旁边有一个多功能空间，用作卧室的走廊、图书馆和入口门。书柜也成为每个卧室的隔膜。在对面，还有另一条走廊，作为所有卧室和多用途房间的连接处，排列得更整齐。当这条走廊的所有连接门都打开时，这些房间合并成一个大连接的房间。两条走廊都采用了磨砂夹层玻璃，以便为一楼的生活区提供更大范围的照明。

The second floor, where all bedrooms are placed has a multifunction space right beside the stairs that’s been used as corridor, library and entrance door for bedrooms. The book cabinets also become partition for each bedrooms. At the opposite side, there is another corridor as the connecting area for all bedrooms and multi purpose room that placed in linier order. When all connecting doors at this corridor are opened, the rooms unite into one big connected room. Frosted laminated glass is applied for both corridors to provide larger range of light for living area on the first floor.

我把倒影池放在楼梯下面，以降低白天的室温，并通过倾听水流的声音来营造一种平静的氛围。右侧有木地板的室内露台，不仅是儿童的游乐场，也可以是偶尔的室内车库。作为一个整体的组成，“Satu House”被设计为一个聪明和深思熟虑的想法，在优化使用空间有限的网站。

I put reflecting pond under the stairs to decrease the room temperature during the day and create a peaceful ambiance by listening to the sound of water stream. An indoor terrace with wooden floor at the right side not only being used as a playground for the children but also can be an occasional indoor garage. As a whole composition, ‘Satu House’ was designed as a smart and thoughtful idea in terms of optimized the use of space for limited site.
