架构师提供的文本描述。这个名为“S屋”的系列项目已经开始为湄公河三角洲地区的低收入阶层提出一个原型住宅。在2012年和2014年4月建造了两个成功的案例研究房屋，一个钢结构模型和一个预制混凝土结构模型之后，在胡志明市建造了一个新的原型S楼3。

Text description provided by the architects. The serial project, called "S House", has begun to propose a prototype house for low-income classes in the Mekong Delta area. After building two successful case-study houses, a steel structure model in 2012 and a precast concrete structure model in April 2014, a new prototype, S House 3, was constructed in Ho Chi Minh City.

这个系列项目的目的是在恶劣的热带气候下为低收入者提供稳定但重量轻、永久但负担得起的住房。尽管存在着地面条件薄弱、台风频繁、潜在地震等局部挑战，但该结构仍具有足够的稳定性，能够抵御自然灾害。整个系列都采用了被动设计方法，包括但不限于：自然照明和通风。

The aim of this serial project is to provide stable but lightweight, permanent but affordable homes for low-income earners in a harsh tropical climate. Although there are many local challenges such as weak ground condition, frequent typhoon and potential earthquake, the structure is stable enough to withstand natural disasters. Passive design methods are applied throughout the series, including but not limited to; natural lighting and ventilation.

结合第一和第二原型的优点，S屋3实现了更高的耐用性，灵活性和更容易的建设，同时保持了可承受性和轻量级的系列。主体结构采用轻质钢结构。细长的钢格墙加固、支撑和加固整个框架。因此，梁的数量被最小化，大大减少了钢的数量相比以前的原型-这种结构只重1200公斤。基座与基础结合在一起，由钢筋混凝土制成。由于这一点，镀锌钢结构是与世隔绝的，确保其耐用性，即使在高温和高湿度的气候。

Combining the advantages of the first and second prototype, S House 3 realizes a higher of durability, flexibility, and easier construction while maintaining the affordability and lightweight of the series. The main structure is made from lightweight steel. Slender steel lattice walls secure, support, and rigidify the whole frames. Thus the number of beams is minimized, reducing steel quantity greatly compared to previous prototypes - this structure only weights 1,200kg. Pedestal, incorporated with foundation, is made of reinforced concrete. Thanks to this, the galvanized steel structure is isolated from the ground, ensuring its durability even in a climate of high temperature and high humidity.

与以前的原型一样，建筑的基本策略是将模块化结构部件和DIY成品结合起来。预制有助于控制质量，成本管理，以及未来的批量生产。镀锌钢框架和预制混凝土基础保证了预定的稳定性和准确性。

As was in the previous prototypes, the basic strategy of construction is a combination of modular structural components and DIY finishes. Prefabrication helps to control quality, cost management, and future mass production. Galvanized steel frame and precast concrete foundation guarantee predetermined stability and accuracy.

这种轻型结构允许较小的基础和小艇的运输能力，因为在越南的某些地区，水道仍然是主要的运输手段。通过浇筑额外的混凝土，如果必要的话，这个紧凑型基础可以在现场扩展。简单螺栓连接的轻型框架也鼓励居民和邻居参与施工。所有组件的重量都比60公斤轻，便于运输和施工-组装整个结构和屋顶只需三个小时。

The lightweight structure allows smaller foundation and transportability by small boats, since waterways are still the dominant mean of transport in certain areas in Vietnam. By pouring additional concrete, this compact foundation can be extended on site if necessary. Light frames with simple bolted connection also encourage dwellers and neighbors to participate in construction. All components are designed to be lighter than 60kg, to allow easier transportation and construction - It takes only three hours to assemble the whole structure and roof.

整理材料都可以很容易地被居民和邻居组装和替换。原型机采用轻质水泥板进行包覆。

Finishing materials can all be assembled and replaced easily by dwellers and neighbors. For the prototype, lightweight cement board is chosen for cladding.

从湄公河三角洲开始，S House项目的目标是将自己扩展到整个越南、东南亚以及世界其他地区-印度和非洲国家-那里的低收入人群正遭受着恶劣环境的困扰。S屋的轻型部件设计成可通过海运集装箱运输。

Starting from the Mekong Delta, the S House project is aiming to expand itself to the entire Vietnam, South East Asia, and to the rest of world - India and African countries - , where low-income people are suffering from poorly built environment. Lightweight components of the S House are designed to be transportable by means of shipping containers.

最新的原型，S屋4，将跨越一个更大的空间。因此，与以前的原型相比，它的使用更加灵活；它不仅限于住房，还可以容纳发展中国家日益需要的零售、学校和诊所等各种功能。

The latest prototype in progress, S House 4, will span a much larger space. Therefore, it is more flexible in use compared to the previous prototypes; Not being limited to housing, it can accommodate various functions such as retail, school and clinic, which are increasingly demanded in developing countries.
