住進懸浮的巨型鳥巢，聆聽鳥語共生自然
Living in a Suspended Giant Bird’s Nest: Listening to Birdsongs and Coexisting with Nature—Biosphere
你有多久沒有遠離城市，屏蔽熙熙攘攘的雜音，走進草木樹林之中，讓鳥語蟲鳴縈繞耳畔，沐浴於陽光樹蔭下，吸收森林芬芳氣息？長期在水泥叢林待久了，回歸自然懷抱竟成為一種難能可貴的享受。是時候給自己一個假期，前往位於瑞典北部村莊 Harads 樹林中的樹屋酒店（Treehotel），像隻自由的鳥兒於松樹林間感受抽離地面的住宿體驗，完全與外界隔絕，這一刻只有自己與所愛之人共享這片原始景致，待在屋內悄悄觀鳥。
How long has it been since you stepped away from the city, blocking out the clamor of daily life, and entered a peaceful forest, surrounded by birdsong and the buzz of insects? When you breathe in the fresh forest air beneath the shade of trees, the experience of being in nature becomes an invaluable pleasure, especially after spending so much time in the concrete jungle. It’s time to give yourself a break—head to Treehotel in Harads, a village in northern Sweden, where you can experience a unique accommodation nestled among the pines. Here, you’ll feel as free as a bird, suspended above the ground, fully disconnected from the outside world, sharing the raw beauty of nature with your loved ones while quietly watching birds from your room.
在這靜謐的樹林內，有個格外有趣引人注目的球體建築懸浮於空，其立面還富滿大大小小的木製鳥屋。原來這是丹麥著名的 BIG 建築事務所與瑞典鳥類學家 Ulf Öhman 密切合作設計的「生態圈」，作為該酒店第八間實驗客房，旨於保護周圍生態棲息地。僅 32 平方公尺的面積，卻為熱愛賞鳥的人士帶來豐富的視覺盛宴，彷彿置身於大自然中心，展開一場與自然的親密邂逅。
In this tranquil forest, there is a particularly intriguing and eye-catching spherical structure suspended in the air, its facade adorned with 350 birdhouses of varying sizes. This is the "Biosphere," designed by Denmark’s renowned BIG (Bjarke Ingels Group) in close collaboration with Swedish ornithologist Ulf Öhman. The eighth experimental room at Treehotel, this unique space is designed to protect the surrounding ecological habitat. Spanning only 32 square meters, it offers birdwatchers a rich visual feast, immersing them in the heart of nature for an intimate encounter with the wild.
實現夢想打造獨特樹屋體驗
Treehotel 為一對瑞典夫婦 Kent Lindvall 和 Britta Jonsson-Lindvall 的夢想實現，也標誌著兩人不畏艱難實踐目標的勇氣。最初這對夫妻分別辭掉各自工作，回到家鄉瑞典哈拉斯共同開設酒店。有次夫婦兩人在俄羅斯釣魚時，與三位瑞典重要設計師 Bertil Harström、Thomas Sandell 和 Mårten Cyren 談及在森林建造樹屋的想法，隨即引起三人的興趣，並陸續構想如何在漫長而寒冷的冬天，打造溫度適宜的樹屋酒店，且須維持與樹木的友好關係。而後，他們想到走進樹林內最常見的風景也包含鳥巢，於是以此為原型概念，邀請世界知名建築事務所設計七間懸浮於樹木間的客房，有意識地喚醒維護自然生態的價值，也不失舒適感與現代美學的融合，帶來鼓舞人心的探險旅程。
Realizing a Dream: Creating a Unique Treehouse Experience
Treehotel is the realization of a dream for Swedish couple Kent Lindvall and Britta Jonsson-Lindvall, and a testament to their courage in pursuing an ambitious vision. The couple left their respective careers behind and returned to their hometown of Harads to open a hotel. During a fishing trip in Russia, they discussed the idea of building treehouses in the forest with three prominent Swedish designers—Bertil Harström, Thomas Sandell, and Mårten Cyren. Their conversation sparked interest, and soon they were developing plans for how to build a warm and welcoming tree hotel amidst the long, cold Swedish winters, while maintaining a harmonious relationship with the surrounding trees. Inspired by the sight of bird nests frequently found in the forest, they decided to use this as the conceptual prototype for their design, inviting world-renowned architects to design seven floating treehouses that would offer a perfect blend of modern aesthetics and nature conservation.
「我們很高興與超群的北歐建築事務所 BIG（Bjarke Ingels Groups）合作，聚焦於未來的概念，使自然環境成為入住體驗中，靈動且有機的一部分。」Kent Lindvall 說道。當充滿熱情與創造力的 Treehotel 創辦人夫婦遇上創意無限的 BIG 建築團隊，原先人們對於木屋的傳統印象即被顛覆。面對瑞典北部森林地區強烈的氣候對比，BIG 採用當地的木材和石材以適應當地惡劣的氣候環境，同時在展現客房獨有個性之餘，仍與森林良好互動。
“We are very pleased to collaborate with the outstanding Nordic architecture firm BIG (Bjarke Ingels Group), focusing on a future-oriented concept where the natural environment becomes an interactive part of the experience,” says Kent Lindvall, founder and co-owner of Treehotel. When the passionate founders of Treehotel met with the endlessly creative BIG team, their traditional ideas about treehouses were turned upside down. Faced with the harsh climate of northern Sweden’s forests, BIG used local wood and stone to design a space that not only stands out in terms of personality but also interacts well with the forest environment.
衡量建築與環境互動，維繫人與鳥類友好關係
「生態圈」的立面布滿 350 個鳥巢，要進入此間客房，需行經一座連接地面與樹冠間的懸索橋，接著進入簡潔而實用的房內，深色內飾和諧融入周圍景觀，柔和的氛圍油然而生。在有限的場域內，局部格狀玻璃鋪敘，締造虛實相映的唯美層次，入住者更能專注於欣賞自然環境，360 度觀賞這片林地。依據當地鳥類的品種和活動頻率，所有鳥巢的尺寸和距離各不相同並向外擴張，確保光線能充分入內，亦不會阻礙向外遠眺的遼闊視野。
Measuring Architecture’s Interaction with Nature: Maintaining Harmony Between Humans and Birds
The facade of the "Biosphere" is covered with 350 birdhouses. To enter this unique room, guests must cross a suspension bridge that connects the ground with the treetop canopy. Inside, the simple yet functional room features dark interiors that seamlessly blend with the surrounding landscape, creating a soft and harmonious atmosphere. The space incorporates grid-patterned glass that adds an artistic layer of depth, allowing guests to focus on the natural environment and enjoy a 360-degree view of the forest. Depending on the local bird species and their activity, the birdhouses vary in size and distance, ensuring that sunlight can flow freely into the room without obstructing the expansive views.
BIG 思考著是否有種方式能沉浸於自然之中，最終以「球形槽居」的形式回應這個想法。在與北博滕郡（Norrbotten County）鳥類協會主席 Ulf Öhman 交談後，也了解到，由於林業砍伐樹木導致鳥類築巢棲息的樹洞減少，加上氣候變化導致昆蟲提前大量繁衍，待鳥蛋孵化時，已錯過捕食蟲類的季節。因此，Treehotel 的「生態圈」可謂維繫人類與自然關係的重要橋梁，既可透過酒店本身向訪客和附近居民展示冬季餵食鳥類的重要性，也帶來沉浸式的森林賞鳥體驗。
BIG envisioned a way to immerse oneself in nature, and the idea of a spherical "swarm of nests" was born. After discussions with Ulf Öhman, chairman of the Norrbotten Ornithological Association, they learned that forestry practices had reduced the number of natural tree hollows where birds typically nest. Additionally, climate change has caused insects to multiply earlier in the year, meaning that by the time bird eggs hatch, the food source is already gone. Thus, Treehotel’s "Biosphere" is an important bridge between humans and nature, allowing guests to experience the vital role of bird nests and feeding in the wild, particularly during the winter months. The initiative also highlights the importance of bird conservation and may inspire visitors to implement similar measures at their own homes.
