矢野青山連結瀨戶大橋意象與在地雪松木，砥部動物園公廁演繹自然曲面美學

由日本矢野青山建築設計事務所（Yano Aoyama Architecture Design）設計的全新公共廁所座落於愛媛縣立砥部動物園（Tobe Zoological Park）入口處，取代既有的老舊設施，提供具備無障礙機能與嬰幼兒照顧設備的全新公共空間。
儘管量體的尺度相當地迷你，設計團隊仍致力於打造一座具「雕塑感」的公共基礎設施，並與動物園的拱形大門以及周邊鬱鬱蔥蔥的林蔭環境形成柔和的對話。
.
公廁由兩座兩公尺見方的立方體量體所組成，主體採用預鑄混凝土塊砌築，外部經由人工鑿刻呈現粗獷且富含質感的紋理，室內大多維持混凝土質感的自然裸露，屋頂則開有大面積方形天井以引進自然採光與通風。
.
引人注目的莫過於覆蓋於量體上方的屋頂結構，設計團隊採用長達十二公尺、由愛媛縣在地雪松製作的交叉積層材（CLT）面板：在結構工程裡頭，木材因自重而產生的撓度（Deflection）通常被視為要處理的結構問題，但團隊反其道而行，在施工過程中精確加入載重，引導木板自然彎曲成一道優雅的弧形曲面，並由邊緣細長的鋼柱輕盈支撐。
.
屋頂與廁所量體間脫開所形成的空間也有助於通風採光，讓廁所內的氣味盡可能以被動方式排出，類似的設計也出現在台灣國道的新營服務區、湖口服務區公共廁所。
.
溫柔的屋頂曲線呼應了園區入口代表「瀨戶大橋」的橋樑意象，為來往的遊客提供了如自然樹冠般開放、明亮且充滿親和力的停留空間。

日本建築師把「木材下垂」的瑕疵變成了超美的弧形屋頂！位於日本愛媛縣「砥部動物園」入口處的全新公廁，由矢野青山建築設計事務所（Yano Aoyama Architecture Design）設計。
這座公廁由兩座 2×2 公尺的預鑄混凝土方塊組成，外牆表面經過人工鑿刻，呈現出超有質感的粗獷紋理。上方屋頂則使用了一整片長達 12 公尺的愛媛縣在地雪松 CLT 板材。
最酷的是，一般建築工法都會想辦法避免木材因重量而彎曲下垂，但建築師卻順應材料的物理特性，在施工時精算載重，讓木板自然下垂成一道超優雅的弧線，順勢呼應了園區入口代表「瀨戶大橋」的意象。
搭配頂部的採光天井與周邊的綠意造景，原本平凡的公廁直接變成一座像樹冠一樣溫柔優雅的雕塑藝術品！
日本建築師事務所 Yano Aoyama Architecture Design（矢野青山建築設計事務所） has completed a public toilet for the Tobe Zoological Park in Ehime Prefecture, creating two chiselled concrete blocks that are topped by a thin roof of naturally curved cedar.
Located alongside the entrance gates of Tobe Zoo, the two public bathroom cubicles replace outdated toilets with fully accessible facilities and baby-changing equipment.
Yano Aoyama Architecture Design（矢野青山建築設計事務所）said that despite the project's modest scale, it sought to create a "sculptural" form, drawing on both the zoo's arched entrance gates and the site's lush, wooded surroundings.
"The gentle roof curve echoes the 'bridge' motif of the existing entrance facilities, themselves a reference to the Seto Ohashi Bridge, a remarkable piece of engineering that established the first land connection between the islands of Shikoku and Honshu," the studio explained.
"The result is not a closed object, but a small piece of public infrastructure that behaves more like a natural canopy forming an open, light, and welcoming space at the zoo entrance," it added.
A pair of cubic volumes measuring two by two metres house the Tobe Zoo Toilet, constructed from precast concrete blocks that were externally chiselled to give a rough, textured finish.
Inside, this concrete structure has been left largely exposed, with large square openings in the roof of each providing daylight and ventilation.
Above, the toilet's canopy was created using a 12-metre-long panel of cross-laminated timber (CLT), made from local Ehime cedar and allowed to naturally bend under its own weight.
While this natural bending, known as deflection, would typically be considered a defect, the studio carefully introduced loading to the roof during construction to encourage it into a gentle, bowed curve, supported by rows of skinny steel columns along its edges.
A curving gutter runs along one edge of the roof, with rain chains guiding water into drains alongside a small garden space planted with shrubs.
"Rather than treating CLT as a neutral industrial board, the design plays with the natural behaviour of timber, especially its tendency to deflect under its own weight, to enhance its physical properties," explained the studio.
"Normally, deflection is considered a problem to be corrected during transport, fabrication, or construction. In this project, it becomes the central architectural idea," it added.
"This gesture is both technical and poetic: the roof is shaped by the material’s own physical nature, and its quiet curve resonates with the surrounding landscape and the memory of the bridges."
