獎項代辦 │ 美國私宅-The Edge 境界

This house was designed to survive what will eventually test it. Wildfire in Malibu is not hypothetical. It is cyclical, seasonal, and accelerating. The challenge was not to harden a home after it was conceived, but to remove combustibility from the architecture itself.

At Point Dume, openness defines living: expansive glazing, deep overhangs, seamless terraces, uninterrupted horizons. Yet these qualities often introduce risk. The project resolved this tension by eliminating fuel at every level of design. Light-gauge steel replaces traditional wood framing, removing ignition from the structural core. Fire-rated exterior sheathing reinforces the envelope, extending endurance under extreme heat.

Exterior decks and terraces, typically vulnerable in wildfire conditions, were conceived from the outset in non-combustible stone, concrete, and fire-retardant composite materials. Nothing exposed invites flame.

The living roof operates as both a landscape and defense system, integrated with full-coverage sprinklers designed to suppress embers and reduce heat accumulation. In the event of a hazard, the sprinkler network can draw directly from the pool through a dedicated high-capacity pump, ensuring water delivery even if municipal supply is compromised. A private on-site hydrant further reinforces this autonomy.

The challenge was not to withdraw from the landscape. It was to remain open to it: intelligently, responsibly, and with the strength to endure.

這棟住宅自設計之初，便將未來可能面臨的極端環境納入整體思考。對於馬里布而言，野火從來不是假設性的風險，而是一種週期性、季節性且日益劇烈的自然現象。因此，真正的關鍵並非在建築完成後再進行補強，而是從建築本質出發，徹底降低可燃性的可能。

位於杜姆角的生活方式，以開放性作為核心精神。大面積玻璃帷幕、深挑簷設計、與室內無縫串聯的露台，以及毫無遮蔽的遼闊視野，共同塑造出與自然緊密相連的居住體驗。然而，這些看似自由通透的設計語彙，同時也伴隨更高的火災風險。為此，該項目在建築的每一個細節中，全面排除可能成為燃料的隱患。結構上以輕鋼取代傳統木構架，從根本降低核心結構燃燒的風險；外牆則採用高耐火性能的覆層材料，即使在極端高溫環境下，依然能維持穩定與耐久性。

戶外平台與露台向來是野火侵襲時最脆弱的區域，因此整體皆以不可燃石材、混凝土與阻燃複合材料打造，避免任何裸露構件成為火勢蔓延的媒介。建築不僅追求形式上的純粹與美感，更讓安全機制自然融入空間本身。

屋頂綠化系統除了提供景觀層次，也肩負防禦功能。全覆蓋式噴灌系統能有效抑制飛散餘燼，降低熱能累積；當危險發生時，系統更可透過專用的大容量水泵直接自泳池取水，即便市政供水中斷，依舊能維持穩定供水。同時，基地內亦設置獨立消防栓，進一步提升整體防災自主性與應變能力。

這座住宅真正回應的，並非如何逃避現實中的風險，而是在理解自然力量之後，依然選擇以開放姿態與環境共存。它以理性與智慧面對挑戰，在美學、責任與韌性之間，建立出一種更具未來性的居住方式。
