宛如巨大的演奏樂器！PCA-Stream 於法國依雲打造 La Source Vive 圓頂音樂廳
.
由法國建築師事務所 PCA-Stream 操刀設計的全新音樂廳「La Source Vive」，坐落於法國依雲（Évian）（對，就是出產礦泉水的那個地方）俯瞰日內瓦湖的斜坡森林裡。
整體構想為「一具巨大的演奏樂器」，提供擁有四百九十個座位的專業室內樂演奏、排練與錄音空間，並與 Patrick Bouchain 於 1993 年打造的經典木造大音樂廳 La Grange au Lac 相互呼應，共同組成由贊助人 Aline Foriel-Destezet 創立的 Les Mélèzes 文化藝術園區。
聲学品質是整座建築設計的核心導向。建築師 Philippe Chiambaretti、Patrick Bouchain 與聲學專家徐亞英 Albert Xu （已於2023年辭世）深度合作，透過數位雙生（Digital Twin）模型與現場反覆測試，精確調校空間聲學。
.
建築由三大量體組成：通透的玻璃前廳、半覆土式圓頂音樂廳以及後台休息室。外觀覆以預先氧化處理的銅瓦，隨著時間推移能完美融入周邊樹林；內部結構則由混凝土聲學外殼與木構造組合而成。
.
演奏廳內部結合了傳統「鞋盒式」與當代「葡萄園梯田式」的空間配置，將觀眾座席呈梯田狀圍繞於舞台四周。
.
室內採用混凝土、灰泥、木材與皮革等純粹材質，牆面雕琢出深達八公分的起伏溝槽以擴散聲音，舞台上方則懸掛客製化鋁合金聲學天井；天花板開設的圓形天窗能引入自然光線並配有遮光系統，使該場館除了室內樂之外，也能靈活支援戲劇、舞蹈與各類藝文講座。

把整座建築當成「音樂樂器」來設計！位於法國依雲（Évian）日內瓦湖畔森林裡的全新音樂廳「La Source Vive」，由 PCA-Stream 事務所操刀。外觀覆蓋著會隨時間變色的預氧化銅瓦，遠看就像一顆埋在森林裡的金屬蛋。
為了達到極致的聲學效果，團隊甚至開發了數位雙生模型來模擬聲音反射。490 席的演奏廳採用了梯田式的座席配置，讓觀眾圍繞著表演者；牆面上刻有深達 8 公分的波浪溝槽來擴散音浪，天花板還開了一扇圓形天窗引入自然光。
除了超棒的音響效果，建築周圍還與景觀團隊共同種植了 150 多棵樹木，並收集雨水灌溉植物，完美結合了自然、音樂與當代建築美學！
French studio PCA-Stream has completed La Source Vive, a domed copper-clad concert hall in Évian, France, designed "as a musical instrument".
Nestled into a sloping woodland site overlooking Lake Geneva, La Source Vive is a 490-seat chamber music hall situated next to Patrick Bouchain's existing 1993 concert hall La Grange au Lac.
Designed to complement the existing venue, La Source Vive provides a dedicated space for chamber music rehearsals, performances and recordings, while the restored 1,000-seat timber hall La Grange au Lac continues to host large-scale orchestral performances.
Together, the two halls form part of Les Mélèzes, a cultural complex encompassing music and performing arts, founded by French philanthropist Aline Foriel-Destezet.
Achieving high-quality acoustics was the central idea guiding the design of La Source Vive, influencing decisions about the building's geometry and material palette.
Philippe Chiambaretti and Patrick Bouchain worked alongside acoustician Albert Xu to "design the building as a musical instrument", exploring how its form, materials and finishes could influence sound quality.
The design process involved acoustic sketches, digital modelling, simulations and repeated on-site testing during construction.
PCA-Stream also developed a digital twin of the project to monitor and refine the hall's acoustic behaviour at different stages.
La Source Vive is set across three volumes – a glazed foyer, the domed concert hall and a separate backstage building containing dressing rooms.
By positioning the project within an existing clearing, the architects aimed to minimise the impact on the woodland site, while enhancing biodiversity through planting more than 150 trees and 200 shrubs alongside landscape studio Coloco.
Linking the old and new halls, the glazed foyer was rebuilt and expanded to include a bar, ticketing area and timber terrace. Rainwater collected beneath the terrace is reused to irrigate the surrounding landscape.
From the foyer, visitors pass through a rock-cut passage before entering a lobby that opens onto the auditorium.
Housed within a domed "partially-buried shell", the concert hall is clad with pre-patinated copper tiles which catch and reflect light, and are designed to weather over time to blend into the surrounding woodland.
Structurally, the concert hall is formed of an acoustic concrete shell wrapped with a second timber frame beneath the copper roof.
Inside, the 490-seat auditorium combines elements of the rectangular "shoebox" concert hall with the more contemporary "vineyard" model, placing audiences on terraced seating around the performers.
The studio opted for a pared-back material palette of concrete, raw plaster, timber and leather throughout.
Curved plaster walls are sculpted with undulating grooves that project up to eight centimetres at audience level, helping to diffuse and reflect sound. Above the stage, a bespoke aluminium canopy was designed to further optimise acoustics.
Solid rose beech timber beams were used for the stage backdrop and flooring, while custom-made dusty orange leather benches are arranged asymmetrically around the stage to create a closer relationship between audience and performers.
An oculus in the ceiling draws natural light inside, fitted with a blackout screen that allows the space to be darkened when required.
Alongside chamber-music performances, La Source Vive accommodates theatre, dance and literary readings, as well as a recording studio space. There are also spaces for workshops, exhibitions and lectures.
A separate volume upslope from the concert hall contains dressing rooms and backstage facilities. Clad in larch and clapboard, its base is made from recycled stone. Elsewhere, stone from the nearby Meillerie quarry was also used for landscaped rockwork.
