Architectural Association students use foraged wood to build "open-air laboratory"

倫敦建筑協會的學生們利用木條和采集的廢木搭建了一座可拆卸的森林亭，稱之為“田野站”（Field Station）。

田野站建造于學校衛星校區里占地4046平方米的胡克公園森林內，必要時方便拆除或重建，學生們可將它作為長期生態研究的露天實驗室。

田野站的木質框架由連接有鋼板和張力桿的白蠟木條構成，而其對角撐和柱狀支撐則是由學生們采集的圓木和分叉樹干制成，這樣的設計使得每個組件都顯得獨一無二。

Students from London's Architectural Association have used timber battens and foraged waste wood to build a demountable forest pavilion called Field Station.
Located within the school's satellite campus, the 4046-square-metre Hooke Park forest, the pavilion is intended as an "open-air laboratory for long-term ecological studies" that is easy to dismantle and relocate when necessary.
While the wooden frame is built from ash battens connected with steel plates and tension rods, its diagonal bracing and column-like supports are formed from lengths of foraged roundwood and forked trunks, making each piece unique.

田野站的設計團隊這么解釋他們的設計理念：“學生們在附近逐漸稀薄的森林的地面上尋找適合形狀、厚度和完整性的樹枝作為采集材料，這種行為呼應過去人們收集柴火的傳統做法。通過利用圓木代替加工木材，田野站對木材的需求量在每砍伐一棵樹的基礎上降低了30%，相當于從物質足跡角度減少了兩整棵成熟的樹�！�

學生們將田野站作為建筑協會的“設計與制作項目”實踐的一部分，該項目還包括2017年建造的鋸木廠庇護所（Sawmill Shelter）。

"Students harvested this material by searching the forest floor of recently thinned compartments for branches of suitable shape, thickness, and integrity, echoing historical practices like estover – the tradition of collecting firewood," explained the team.
"By utilising round timber in place of processed lumber, the Field Station required 30 per cent less timber per tree felled, reducing its material footprint by two mature trees," it added.
The students constructed Field Station as part of the Architectural Association's Design + Make Programme, which also saw the construction of Sawmill Shelter in 2017.

學生們與Arup工程公司合作，應用計算機技術輔助將這些不規則的木制部件設計到結構中。每個組件都經過掃描，在計算機中建模，然后再使用機器手臂切割出每個連接區域。

田野站亭頂的張力桿將桁架結構保持在壓縮狀態，使屋頂在四周向外懸挑三米。

設計團隊表示：“這種技術創新能夠容納材料的離心性，展示先進制造技術如何與自然、不規則的材料協調一致，從而創造可擴展的建筑解決方案。田野站作為一個理想化的模型，展示了現代建筑對林地管理和碳封存的積極貢獻潛力�！�

Working with engineering firm Arup, the students used computer-aided design to incorporate these irregular wooden components into the structure.
Each component was scanned and placed into a computer model before areas for each connection were cut using a robotic arm.
The canopy's tension rods hold the truss structure in compression, allowing the roof to cantilever outwards by three metres on all sides.
"This technological innovation accommodates material eccentricities, and showcases how advanced manufacturing techniques can be harmonised with natural, irregular materials to create scalable architectural solutions," said the team.
"Field Station stands as an aspirational model, demonstrating the potential of modern architecture to contribute positively to woodland management and carbon sequestration."

這些從森林采集的木制構件與預制組件一起打包并運送到現場，讓田野站能夠在短短10天內建造完成。

這樣的設計可以讓此類戶外場站更具有靈活性和可移動性，能夠適應森林定期的砍伐周期。

The foraged components of the structure are combined with prefabricated elements that were flat-packed and brought to site, enabling Field Station to be constructed in just 10 days.
This design is also intended to make the pavilion flexible and relocatable, able to adapt to the forest's periodic felling cycles.

田野站亭頂采用波紋金屬板和中央波紋塑料天窗制成，地板采用了云杉木鋪設，建在鋼樁基礎之上。

The roof of the pavilion is finished with corrugated metal sheets and a central corrugated plastic skylight, while an area of spruce decking was created for the floor, which stands on a foundation of steel piles.
