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.

強調再利用與韌性的敘事核心，霍瑟姆住宅（Hotham）將一棟 1937 年的兩次世界大戰期間平房重塑為可持續的當代居所。由奧斯汀?梅納德建筑事務所（Austin Maynard Architects）設計，項目保留原有磚結構小屋，新增兩座附屬建筑，將社區遺產與生態創新融為一體。每一處材質與布局選擇，都彰顯著減少隱含碳、尊重郊區建筑歷史的堅定理念。

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.

設計的核心在于保留既有建筑肌理：回收的紅磚與屋頂瓦片被重新用于新建部分，維系著與過往的切實聯結。原有小屋成為中央核心，通過玻璃走廊連接兩座新附屬建筑。一座設有保溫臥室，提供靜謐休憩空間；另一座朝向花園，成為社交中心。中央動線兩端的無框玻璃模糊了室內外界限，讓陽光與花園景致灑滿空間。

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.

住宅專為堪培拉的極端氣候 —— 炎熱夏季、寒冷冬季與巨大晝夜溫差 —— 量身打造，配備高保溫圍護結構。熱斷橋雙層玻璃窗、厚實保溫層與外部遮陽設施緩解了極端氣溫影響。混凝土樓板發揮熱質儲能作用，吸收冬日陽光并逐步釋放熱量。夏季通過可開啟玻璃實現交叉通風，自然降溫；電動水循環熱泵系統提供溫和供暖，打造出全年舒適的宜居空間。

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.

可持續理念不僅體現在圍護結構，更延伸至能源與水資源系統。7.7 千瓦屋頂太陽能電池板為全電氣化住宅供電，并預留未來儲能電池安裝空間。高效熱泵驅動供暖、熱水與泳池系統，5000 升地下雨水箱用于花園灌溉。透水步道與保留的成年樹木減少雨水徑流、為周邊降溫，彰顯了兼顧住宅與環境的整體生態宜居理念。

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.

材質選擇以耐用性、低維護成本與低碳排放為核心。拋光混凝土、水磨石、天然石材與合規采購木材構成室內飾面，摒棄多余裝飾。外部來看，新附屬建筑復刻了原有平房的尺度與屋頂坡度，與街景無縫相融。街道視角的簡約之下，是精心打造的室內空間 —— 原始材質與功能性設計交織出溫暖質感。霍瑟姆住宅證明，適應性再利用能夠尊重過往、服務當下、守護未來，每一塊磚瓦都承載著這份可持續的承諾。
