架构师提供的文本描述。在湄公河三角洲，平均每月收入低于100美元的人主要居住在廉价的临时住房中。具有讽刺意味的是，糟糕的结构导致了高昂的维修费。因此，低成本但永久性的住房是这里的一个紧迫的社会问题.在这种情况下，“房子”项目的目标是在每单位4，000美元(30平方米)的预算范围内提供稳定但重量轻、永久但负担得起的住房。

Text description provided by the architects. People in Mekong Delta, with an average income under 100 USD per month mainly live in cheap temporary houses. Ironically, poor structures result in high maintenance fee. Therefore, low-cost but permanent house is an urgent social issue here. With the given situation, the aim of "s house" project is to provide stable but lightweight, permanent but affordable homes within a budget of 4,000 USD per unit (30 sqm).

该项目的第一阶段于2012年以钢框架原型启动。自2013年以来，为了在热带气候下追求更高的稳定性和热舒适性，设计了一种新型预制混凝土框架原型，并在龙安省建造了两座房屋。

The first phase of the project started in 2012 with a steel frame prototype. Since 2013, in pursuit of higher stability and thermal comfort in a tropical climate, a new prototype with precast concrete frame was designed and two houses is constructed in Long An Province.

第二个原型的概念是将模块化组件和DIY策略结合起来。预制有助于控制质量和成本，以及未来的批量生产。预制混凝土框架和基础保证了预定的稳定性和准确性。这种轻量级的结构使得小型船只的基础更小，运输能力更强，因为在湄公河三角洲，水路仍然是主要的运输方式。带有简单螺栓连接的轻型框架也鼓励居民参与施工。当地采购，整理材料都可以很容易地由居民和邻居为未来的变化或扩展而进行组装和替换。

The concept of the second prototype is to combine modular components and DIY strategy. Prefabrication helps control quality and cost, and future mass production. Precast concrete frame and foundation guarantee predetermined stability and accuracy. The lightweight structure allows smaller foundation and transportability by small boats, since waterways are still the dominant transportation in Mekong Delta. Light frames with simple bolted connection also encourage dwellers to participate in construction. Locally sourced, finishing materials can all be assembled and replaced easily by dwellers and neighbors for the future change or extension.

为了应对该地区恶劣的天气，该项目采用了被动设计策略。尼帕棕榈和瓦楞纸水泥是结合在一起形成一个“双屋顶”，它有助于保护居民免受过度降雨，同时提供足够的热舒适。聚碳酸酯面板允许自然光进入和减少人工照明的需要，而屋顶和墙壁之间的差距是促进自然通风。由于日本棕榈树在湄公河三角洲几乎不需要花费，所以它不仅是当地熟悉的材料，而且与周围的风景也很协调。

To cope with harsh weather of the region, the project utilizes passive design strategies. Nipa palm and corrugated cement is combined to form a "double roof", it helps protect dwellers from excessive rain while providing sufficient thermal comfort. Polycarbonate panels allow natural light to enter and reduce the need for artificial lighting, while the gap between the roof and walls is to promote natural ventilation. Since nipa palms cost next to nothing in Mekong Delta, it is not only a familiar material to the locales but also in harmony with the surrounding scenery.

经过二次施工，第三原型具有更高的耐久性，更轻的结构，更合理的部件正在进行中。

After construction of the second, the third prototype with higher durability, lighter structure and more reasonable components is on progress.
