设计理念与环境融合：“云街”项目最引人入胜之处在于其对设计理念的深刻理解。建筑师并非追求标新立异，而是致力于将建筑融入周围环境，强调与社区的和谐共生。这种“背景式建筑”的理念体现在外观的朴素以及材料的选择上。项目在设计之初就考虑了与环境的互动，例如拆除前围栏，创造开放的前院，融入当地植物和休闲区，增强了与社区的连接。这种设计策略充分利用了社区环境的优势，打造出一个宜居的家庭友好型住宅。

空间布局与功能分区：项目在空间布局和功能分区方面展现了卓越的规划能力。“云街”通过巧妙的空间设计，实现了功能性和舒适性的完美结合。功能空间被划分为四个区域：中心是北向庭院花园，公共区域围绕其展开，两侧分别是父母区和儿童区，全部朝北，以获取充足的阳光，而公用设施则位于南侧。此外，房间并非传统的矩形设计，倾斜的墙壁和天花板使建筑形态更加独特，并将建筑分解为两个双层亭子的结构，从而增强了空间的多样性和趣味性，为居住者提供了更丰富的体验。

可持续性与低碳理念：“云街”项目在可持续性设计方面堪称典范。建筑师充分利用被动式太阳能设计原则，注重热舒适性、自然通风、采光和绿化等因素，并将其融入到开口的设计、材料选择和细节处理中。项目核心结构采用了夯土，具有低碳、隔热和隔音等优良特性，同时搭配光控阳台、通风窗户和智能遮阳，有效减少了对人工气候控制的依赖。最终，通过生命周期分析，该项目实现了与澳大利亚普通住宅相比230%的全球变暖潜力降低，证明了大体量建筑同样可以实现卓越的环境表现，体现了可持续设计的巨大潜力。

建筑师提供的文字描述Cloud Street是一个近郊社区的一部分，是一个拥有广泛项目的大型家庭住宅，是一座两层楼高的建筑，有着自己的特色，看起来很朴素，毫不费力地融入了周围的环境。它反映了我们建筑作为背景的精神，避免脱颖而出，但从成为其他事物的一部分和为其他事物做出贡献中汲取力量，在这种情况下，它是一个家庭友好社区中轻松的郊区街道。
Text description provided by the architects. Part of an inner suburban neighbourhood, Cloud Street – a large family home with an extensive program - is a two-storey building with its own identity that appears modest and merges effortlessly into its surroundings. It reflects our ethos of building as background that avoids standing out but draws its strength from being part of and contributing to something else, in this case a relaxed suburban street in a family friendly neighbourhood.

我们以设计朴素的建筑而闻名，对299平方米的房子感到不舒服。这促使我们采用了一种设计方法，尽管它的规模很大，但它是隐性的、对环境敏感的、考虑未来使用的、接触社区的，最重要的是，它的全球变暖潜力远低于澳大利亚的普通住宅。
We are known for designing modest buildings and were uncomfortable with a 299 sqm house. This drove our approach to deliver a design that – despite its size – is recessive, environmentally sensitive, considers future use, reaches out to the community and – most importantly – has a significantly lower global warming potential than the average Australian dwelling.

隐性外观从最初的概念到平面图、形式、材料选择和细节。功能和空间概念分为四个区域：中心围绕北部庭院花园的公共区域，父母和孩子在两侧，都朝北，公用设施在南侧。
Appearing recessive carries through from the initial concept to floor plans, form, material selection and detailing. The functional and spatial concept is an arrangement split into four zones: communal areas in the centre around a northern courtyard garden, parents and children to either side, all facing north, and utilities along the south.

Floor Plan

我们选择的房间不是矩形的：墙壁是倾斜的，天花板是倾斜的。这允许表格分解成小部分。这座建筑似乎由两个双层亭子连接在一起：父母在后面，孩子和客人在前面。
We chose our rooms not to be rectangular: the walls are angled, and ceilings sloped. This permits the form to break down into small parts. The building appears to be held together by two double-storey pavilions: parents at the rear, and children and guests at the front.

Elevation

父母侧楼很隐蔽，厨房后面有一个楼梯，通往带私人露台的主卧室，而孩子侧楼则有一个开放的圆形木楼梯、一根消防杆和一个可以通往街道的花园。正面在它的存在下是随意的，并公开地与社区相连。我们拆除了前围栏，创造了一个开放的前院，里面种着当地植物和休闲休息区。
Whereas the parents' wing is secluded, with a staircase tucked behind the kitchen leading to the main bedroom with a private terrace, the kids' wing features an open circular timber staircase, a fireman's pole and access to a garden that can open up to the street. The frontage is casual in its presence and openly connects to the neighbourhood. We removed the front fence and created an open front yard with native plantings and casual sitting areas.

在多个层面上尊重其环境是云街设计、建造和使用的核心。利用被动式太阳能设计原则，我们让热舒适性管理、阳光照射、自然气流和通风、声学和绿化等考虑因素为开口的布局、大小和位置以及我们的材料选择提供信息。
Respectfully engaging with its environment on multiple levels is at the core of Cloud Street's design, construction, and use. Leveraging passive solar design principles, we let considerations such as the management of thermal comfort, sunlight access, natural airflow and ventilation, acoustics, and access to greenery inform the layout, size and location of openings and our material choices.

尽管形式上很复杂，但这座房子是围绕夯土脊柱经济建造的，因其低碳、热质量、声学质量以及光线对其表面的动画效果而被选中。光控阳台、精心布局的自然通风窗户和带集成自动遮阳篷的厚墙确保了稳定的室内温度，减少了对人工气候控制的依赖。它被注定要优雅成熟的木材所包裹，象征着与自然的共生关系。
Despite its formal complexity, the house was economically constructed around a rammed earth spine, selected for its low embodied carbon, thermal mass, acoustic quality, as well as the way light animates its surface. A light-controlling veranda, strategically placed windows for natural ventilation, and thick walls with integrated automated awnings ensure stable indoor temperatures - reducing reliance on artificial climate control. Clad in timber destined to mature gracefully, it symbolizes a symbiotic relationship with nature.

我们的生命周期分析评估了Cloud Street的整个生命周期碳影响，结果表明，与澳大利亚普通住宅相比，其全球变暖潜力降低了230%，这表明大型建筑也可能对环境敏感，并有助于进一步阐明可持续设计的巨大潜力。
Results of our life cycle analysis, which assessed Cloud Street's whole-life carbon impact, demonstrated a 230% saving in its global warming potential compared to the average Australian dwelling – providing an indication that large buildings can also be environmentally sensitive and helps to further illuminate the expansive potential of sustainable design.
