Emphasizing the narrative of reuse and resilience, Hotham reimagines a 1937 interwar bungalow into a sustainable contemporary home. Designed by Austin Maynard Architects, the project preserves the original brick cottage while adding two pavilions, blending neighbourhood heritage with eco-conscious innovation. Every material and layout choice speaks to a commitment to reducing embodied carbon and honoring the suburb’s architectural history.

强调再利用与韧性的叙事核心，霍瑟姆住宅（Hotham）将一栋 1937 年的两次世界大战期间平房重塑为可持续的当代居所。由奥斯汀・梅纳德建筑事务所（Austin Maynard Architects）设计，项目保留原有砖结构小屋，新增两座附属建筑，将社区遗产与生态创新融为一体。每一处材质与布局选择，都彰显着减少隐含碳、尊重郊区建筑历史的坚定理念。

The design’s heart lies in preserving the existing fabric: salvaged red bricks and roof tiles are reused in new construction, maintaining a tangible link to the past. The original cottage forms the central core, connected to two new pavilions via glazed corridors. One pavilion houses insulated bedrooms, offering a quiet retreat, while the other opens to the garden as a social hub. Frameless glass at the ends of the central circulation spine blurs indoor-outdoor boundaries, flooding spaces with daylight and garden views.

设计的核心在于保留既有建筑肌理：回收的红砖与屋顶瓦片被重新用于新建部分，维系着与过往的切实联结。原有小屋成为中央核心，通过玻璃走廊连接两座新附属建筑。一座设有保温卧室，提供静谧休憩空间；另一座朝向花园，成为社交中心。中央动线两端的无框玻璃模糊了室内外界限，让阳光与花园景致洒满空间。

Tailored to Canberra’s extreme climate—hot summers, cold winters, and large temperature swings—the home features a highly insulated envelope. Thermally broken double-glazed windows, robust insulation, and external shading mitigate temperature extremes. The concrete slab floor acts as thermal mass, absorbing winter sun and releasing warmth gradually. Cross-ventilation through operable glazing cools interiors naturally in summer, while an electric hydronic heat pump system provides gentle heating, creating a comfortable year-round haven.

住宅专为堪培拉的极端气候 —— 炎热夏季、寒冷冬季与巨大昼夜温差 —— 量身打造，配备高保温围护结构。热断桥双层玻璃窗、厚实保温层与外部遮阳设施缓解了极端气温影响。混凝土楼板发挥热质储能作用，吸收冬日阳光并逐步释放热量。夏季通过可开启玻璃实现交叉通风，自然降温；电动水循环热泵系统提供温和供暖，打造出全年舒适的宜居空间。

Sustainability extends beyond the envelope to energy and water systems. A 7.7 kW rooftop solar array powers the fully electric home, with provisions for future battery storage. Efficient heat pumps run heating, hot water, and pool systems, while a 5,000-litre rainwater tank irrigates the garden. Permeable paths and preserved mature trees reduce stormwater runoff and cool the surrounding area, embodying a holistic approach to eco-conscious living that nurtures both the home and the environment.

可持续理念不仅体现在围护结构，更延伸至能源与水资源系统。7.7 千瓦屋顶太阳能电池板为全电气化住宅供电，并预留未来储能电池安装空间。高效热泵驱动供暖、热水与泳池系统，5000 升地下雨水箱用于花园灌溉。透水步道与保留的成年树木减少雨水径流、为周边降温，彰显了兼顾住宅与环境的整体生态宜居理念。

The material palette prioritizes durability, low maintenance, and low embodied carbon. Polished concrete, terrazzo, natural stone, and ethically sourced timber form internal finishes, avoiding unnecessary decoration. Externally, the new pavilions mirror the original bungalow’s scale and roof pitch, blending seamlessly into the streetscape. This modesty from the street belies a thoughtfully crafted interior where raw materials and functional design create warmth. Hotham proves that adaptive reuse can honor the past, serve the present, and protect the future—one brick at a time.

材质选择以耐用性、低维护成本与低碳排放为核心。抛光混凝土、水磨石、天然石材与合规采购木材构成室内饰面，摒弃多余装饰。外部来看，新附属建筑复刻了原有平房的尺度与屋顶坡度，与街景无缝相融。街道视角的简约之下，是精心打造的室内空间 —— 原始材质与功能性设计交织出温暖质感。霍瑟姆住宅证明，适应性再利用能够尊重过往、服务当下、守护未来，每一块砖瓦都承载着这份可持续的承诺。
