从这些层次上看，人们可以看到周围低矮的房屋，朝向河流，壮丽的森林景观和各种古老的建筑。

From these levels one has a great view over the surrounding low-rise houses, towards the river, magnificent forest scape and various aged buildings.

这一地区的建筑物因越战而受损。他们中的大多数也是在欧洲设计的启发下用殖民风格的立面进行翻新的。现在，不管它们的高度如何，有些建筑仍然模仿这种立面风格。

The buildings in this area were damaged by the Vietnam War. Most of them were also renovated with colonial style façades inspired by European designs.Nowadays, regardless of their height, some of the buildings still imitated this kind of the façade style.

客户不需要改变现有建筑的信封，而是创建一个独特和有吸引力的附加，将这座建筑变成城市的一个图标。

The client required not to change the envelope of the existing building, but create a unique and attractive addition that change this building into an icon of the city.

挑战是通过插入一种具有独特和当地材料的新结构来对建筑物产生影响。

The challenge was to create an impact on the building by inserting a new structure with unique and local material.

在研究了当地的几种材料，如砖石等之后，我们选择了竹子作为工作对象。通过我们的经验，我们知道竹子是很容易在这种热带气候，减少建设时间和预算。在这个项目中使用竹子的本质是“轻盈”。如竹子，可由少数工人提起，并可方便地用起重机运输到最高的楼层。

After studying several local materials such as brick, stone, etc we chose bamboo to work with. Through our experience, we know bamboo is easily to access in this tropical climate which reduces construction time and budget. The essence of using bamboo in this project is “lightness”. As bamboo which can be lifted up by a few workers and easily transport to the highest floor by a crane.

此外，可以在不增加任何结构支撑的情况下安装竹子结构。

In addition, it is possible to install the bamboo structure without any additional structural support. 

 Ceiling Plan

对于7F(顶层)，我们用竹子材料覆盖现有的混凝土结构，将其转化为创造空间品质的元素。由于天花板上也覆盖着竹子，城市里的行人可以认出街道上的空间。

For the 7F (top floor), we covered the existing concrete structure with bamboo material, it converted into an element that creates spatial qualities. Because the ceiling is covered with bamboo as well, pedestrians in the city can recognize the space from the street.

现有结构有10根竹柱和4根柱。这些柱子优雅地将空间划分成不同的私人区域。像洞穴一样的空间在整体上是永远无法体验的，但是每个地方都可以看到周围的城市。

There are 10 bamboo columns to hide the existing structure and 4 additional columns. These columns elegantly divide the space into diffrent private areas. The cave-like space can never be experienced in its totality, but every place has a view to the surrounding city.
