架构师提供的文本描述。这座可扩展的房屋(简写为卢巴)是印尼巴丹(Batam)等迅速发展的城市所面临挑战的一部分，也是对快速发展的巴丹(Riau群岛)等城市所面临挑战的可持续应对之一。巴丹曾经是一群有几千居民的沉睡渔村，在不到40年的时间里发展成为一个拥有100多万人口的大都会。在新的自由贸易协定和巴丹靠近新加坡的推动下，这一惊人的增长并没有减弱。来自印度尼西亚各地的年轻移民搬到那里寻找他们的财富。到2015年，巴丹被评为世界上增长最快的城市。因此，城市面临着重大的规划问题：如何容纳涌入的移民？如何提供足够的住房以及适当的水和污水系统？如何资助足够的交通基础设施，并提供学校、大学和医院？

Text description provided by the architects. The expandable house (‘rumah tambah’ in Bahasa Indonesia, or rubah for short) is designed to be one part of a sustainable response to the challenges of rapidly developing cities like Batam, in Indonesia’s Riau Archipelago. Once a collection of sleepy fishing villages of a few thousand inhabitants, Batam developed to be a cosmopolitan city of over one million people in less than 40 years. This remarkable growth, fueled by a new free trade agreement and Batam’s proximity to Singapore, has not abated. Young migrants from all over Indonesia moved there to seek their fortune. By 2015 Batam was named the fastest growing city in the world. As a consequence, the city was confronted by major planning problems: How to accommodate the influx of migrants? How to provide sufficient housing, and appropriate water and sewage systems? How to fund adequate transport infrastructure, and provide schools, universities and hospitals?

可扩展住宅项目的重点是住房的挑战。这样做的办法是，允许建筑物按照其居民的资源消耗和支出或新陈代谢的波动模式灵活配置。实际上，这意味着了解家庭创收和支出、水、能源和粮食消费以及废物生产的模式。由于这种新陈代谢通常是不平衡的，而且往往是不稳定的，因此重要的是建筑可以成为一个住宅和创收单位，在当地管理自己的废物、水和能源。

The expandable house project focuses on the challenge of housing. It does so by allowing the building to be flexibly configured around the fluctuating patterns of resource consumption and expenditure, or metabolism, of its residents. Practically this means understanding the patterns of household income generation and expenditure, water, energy and food consumption, as well as waste production. As this metabolism is usually uneven and often precarious, it is important that the architecture can be a dwelling and income generating unit, that manages its own waste, water and energy locally.

可扩展房屋的设计遵循以下五项原则：

The expandable house is designed around the following five principles:

1.三明治组。房子提供一个屋顶，可以悬挂，地板和地基(面包)，可以支持多达三层(填充)。这一制度允许灵活的融资，开发商或国家住房机构提供屋顶和地基，而居民提供填补他们的情况和预算允许。它还有助于满足重要的创收功能(商店、咖啡馆、车库、家庭手工业)以及住宅。

1. Sandwich Section. The house provides a roof that can be hoisted, and floor and foundations (the bread) that can support up to three additional floors (the filling). This system allows flexible financing whereby the developer or state housing agency provides the roof and foundations, while the residents provide infill as their circumstances require and budget allows. It also helps accommodate crucial income generating functions (shop, café, garage, cottage industry) along with dwelling.

2.家庭密度。这所房子鼓励家庭在垂直层面上进行致密化。这支持了住房和就业同地办公的好处。它还有助于减少在可耕地上的定居点足迹，以及对昂贵的基础设施(道路、电力和饮用水网络)的需求。

2. Domestic Density. The house encourages domestic densification in the vertical dimension. This supports the benefits of co-location of dwellings and employment. It also helps to reduce the settlement footprint on arable land, and the demand for expensive infrastructures (roads, electrical and potable water networks).

3.分散系统雨水收集和太阳能发电技术、污水处理和化粪池系统以及被动冷却原理在当地与可扩展的房屋结合起来，避免了昂贵和往往不可靠的集中式或“大管道”基础设施提供办法。

3. Decentralized Systems. Rainwater harvesting and solar electricity generating technologies, sewage and septic tank systems, and passive cooling principles are integrated locally with the expandable house, avoiding expensive and often unreliable centralized, or ‘big pipe’, approaches to infrastructure provision.

4.生产性景观。这座可扩展的房屋将当地的食品和建筑材料生产能力融为一体。这是通过将竹园和厨房花园纳入房屋的规划逻辑来实现的，并有助于使可扩展房屋的资源基础进一步多样化。

4. Productive Landscapes. The expandable house integrates food and building material production capacity locally. This is achieved by integrating bamboo plantations and kitchen gardens into the planning logic of the house, and helps further diversify the resource base of the expandable house.

5.种子包装。可扩展房屋设计为种子包装，包含技术、材料战略和规划准则，可根据当地社会、文化和环境条件以不同方式发展。我们的意愿是，多样化的热带城镇将从共同的种子包装中成长。

5. Seed Package. The expandable house is designed as a seed package, containing technologies, material strategies and planning guidelines that can develop in different ways depending on local social, cultural and environmental conditions. We intend that diverse tropical towns will grow from the common seed package.
