架构师提供的文本描述。这座房子位于越南胡志明市一处新的住宅开发项目内，由于雨水排水系统差，经常受到洪水的威胁。因此，客户要求地板从地面尽可能高，不超过允许的高度限制。我们建议在4根混凝土柱和横梁上暂停整个体积，从而在房子下面创造一个多用途的室外空间。

Text description provided by the architects. Located within a new residential development in Ho Chi Minh city, Vietnam, the house is threatened by frequent flooding due to poor storm drain system. Consequently, the client requested the floors to be raised as high from the ground as possible without exceeding the allowable height limit. We propose to suspend the entire volume on 4 concrete pilotis and beams, thereby creating a multipurpose outdoor space beneath the house.

在定期的基础上，这一空间可用于娱乐活动，如锻炼，卡拉OK，和非正式聚会。在必要的时候，这个空间可以与一楼的露台结合起来，形成一个更大的家庭聚会和聚会的区域。

On a regular basis, this space can be used for recreational activities such as exercising, karaoke, and informal gathering. When necessary, this space can combine with the terrace on the first floor, forming an even larger area for family get-together and parties.

其余的程序在每一层交错，为私人花园和露台腾出空间。在中间，由梯田和楼梯组成的循环竖井使房子自然通风。在圆形钢柱的支撑下，屋顶在太阳和阁楼之间形成了一个缓冲地带，以减轻越南的热带热。

The remaining program is staggered on each floor to make room for private gardens and terraces. In the center, a circulation shaft consisting of terraces and stairways keeps the house naturally ventilated. Supported by a grid of circular steel columns, the roof generates a buffer zone between the sun and the attic to mitigate the tropical heat of Vietnam.

浮动房屋被设计成三个不同的元素：地基、有人居住的体积和屋顶；然而，它们都由四个支柱连接在一起，在空中毫不费力地“漂浮”。

Floating House is designed as three distinct elements: foundation, inhabited volume, and roof; yet they are all connected together by the four pilotis to “float” effortlessly in the air.
