Alexander Symes Architect：本案位于澳大利亚伊拉瓦拉地区，是一个年轻家庭的小型附加住宅。建筑坐落在陡峭的场地上，整体被抬高，环绕在一棵有60年树龄的胡椒树树冠之间。该项目按照国际被动式建筑标准建造，秉承真正的可持续性核心理念，具体体现在天然材料面板、高性能设计和强亲生物性方面。两个悬臂式的侧翼各有一个绿色屋顶，上面种满了澳大利亚本土植物，使建筑与景观融为一体。
Alexander Symes Architect：Pepper Tree Passive House is a small secondary dwelling to a young family’s home in the Australian Illawarra region, perched on a steep site and elevated into the canopy of the site’s eponymous 60 year old Pepper Tree. Built to the international Passive House standard, true sustainability is at the core ethos of the project – embodied between the natural material palette, high performance design and strong biophilic connection. The two cantilevered wings each host a green roof, filled with native Australian plants, blending the building into the landscape.

这座“第二住宅”为客户发展中的公司提供了急需的独立办公空间，同时也为客人提供了住宿空间，适合短期居住。对现有住宅的改造改善了空间的热舒适性，并创造了新的娱乐空间。项目使用自然材料和原材料，包括大量的木材、特有的屋顶花园和树冠平台，加强了整个场地的亲生物性与周围环境的联系。
The secondary dwelling provides a much needed separate office space for the clients’ growing company, as well as providing space for guest accommodation and being geared for short-stay accommodation. The works to the existing home improve the thermal comfort of the space and create new entertaining spaces throughout. Between the natural and raw material palette including extensive timber use, endemic rooftop gardens and tree canopy deck, the biophilic connection of the entire site is strengthened with its immediate environment.

“第二住宅”位于树冠下的陡峭场地上，通过种满植物的绿色屋顶整体抬升了自然地面，回收的木板覆层也使建筑更加与环境相融。曾暴露在街角的环绕式住宅平台创造了新的娱乐空间，为建筑和街道之间提供了噪音和视觉缓冲，并能直接透过树冠看到肯布拉山脉。该项目在不过度开发或牺牲亲生物性联系的情况下，为郊区场地增加了非常必要的可用楼面空间。
Nestled into the tree canopy of the Pepper Tree, the secondary dwelling sits lightly on the steep site and elevates the natural ground via its green roofs, with the recycled Shou Sugi Ban cladding allowing the building to blend into its environment. Previously exposed to the street corner below, the wrap-around deck to the existing home creates spaces for entertaining that provide both a noise and visual buffer to the street, and direct views over the street tree canopies towards Mount Kembla. The project adds much needed usable floor space to the suburban site without overdeveloping or sacrificing biophilic connection.

该项目通过使用回收和废弃材料，在不影响材料质量的情况下有效降低了成本。被动式房屋标准和12kw光伏板系统意味着该项目的整体电量消耗仅为同等规模房屋的14%（减少了86%），大大降低了客户的终身使用成本。相对于将160平方米的住宅完全升级为标准的被动式建筑，在未来的极端气候条件下，只升级60平方米的建筑面积将会更加舒适。这一方法为创建小型的、经得起未来考验的附加建筑提供了先例，让我们能够适应气候变化的同时，无需花费大量成本来升级现有的全部住宅空间。
By using salvaged and waste materials throughout, costs were significantly reduced without sacrificing material quality. Passive House standard and 12kW photovoltaic panel system means that the project’s overall grid energy consumption is only 14% of a comparable sized home (86% reduction), significantly reducing the lifetime cost to the clients. As opposed to thermally upgrading 160m2 to the passive house standard, only 60m2 will actually be comfortable in future peak climatic conditions. This approach provides a precedent for creating small future-proofed additions so that we can be climate adaptive without the massive cost of upgrading all existing dwellings.
