捷克共和國斯特拉瓦市將創建一個擁有 1300 個座椅的音樂廳，毗鄰現有的 20 世紀文化館。“完美的原聲樂器”的概念是為斯特拉瓦的楊納切赫愛樂管弦樂團提出的，該樂團是捷克頂尖的現代音樂管弦樂團。

音樂大廳面向北面的公園，有效地屏蔽了主林蔭大道到南側的噪音。一個新的入口盤旋在濱海廣場之上，將公眾從歷史悠久的文化之屋運送到音樂廳的采光大廳。新舊之間的戲劇性互補對比為斯特拉瓦創造了一個文化地標。

新建筑預示著斯特拉瓦城的未來。在由混凝土和楓木構成的延伸式葡萄園式規劃中，光滑的標志性鋼箱子里裝著一個“樂器”，即容納 1300 個座位的音樂廳。捷克作曲家，萊奧什·雅納切克（Leos Janacek）的時間理論將為音樂廳的內部幾何結構與排序提供指引。聲學墻板根據三種變體中的 Scasovani 或節奏組織而成。

1.Znici = 發聲

2.Scitaci = 計數

3.Scelovac = 求和

該建筑使用簡單的材料：入口采用透明玻璃，建筑體量采用輕質鋅包層，與文化之屋的瓷磚和石灰華基底形成互補對比。采用了藍灰色鋅包漿，因為它是 100% 可回收的環保材料，而且它在彎曲幾何表面具有極高的靈活性。室內由楓木制成，猶如一把小提琴，而且還能夠提供理想的音響效果。吸音的粗灰墁層和粗糙的皺折混凝土補充了聚集空間的體驗。

玻璃幕墻和天窗為建筑注入了自然光，減少了對不可再生能源的依賴。游客置身于一個充滿陽光的環境中，每一天每個季節都會有不同的體驗。在白天，天窗可以增加氣氛；到了晚上，當建筑從內部發光時，天窗會亮起并把光線投射到濱海廣場和公園上。

The city of Ostrava in the Czech Republic will build a new 1,300 seat concert hall sited adjacent to the existing 20th century Cultural Center.The concept of a “perfect acoustic instrument in its case” is proposed for Ostrava’s Janacek Philharmonic Orchestra, the leading Czech orchestra for commissioning Contemporary Music.

The Concert Hall faces the existing Park to the North, thus minimizing noise from the main boulevard to the South.A new entrance hovers over the Esplanade and transports the public above the historic House of Culture into a sky-lit lobby for the Concert Hall.The dramatic complimentary contrast of old and new creates a Cultural Landmark for Ostrava.

The new architecture points to the future of the city of Ostrava.The smooth iconic steel case holds an “instrument”, the 1300-seat Concert Hall, in an extended vineyard type plan made of concrete and maple wood.Czech composer, Leos Janacek’s theories of time will guide and give order to the concert hall’s interior geometry.Acoustic wall panels are organized according to Scasovani, or rhythm in three variants.

1.Znici = sounding

2.Scitaci = counting

3.Scelovac = summing

The proposed building uses a simple material palette: clear glass for the entranceway and lightweight zinc cladding for the building volume in complimentary contrast to the ceramic tile and travertine base of the House of Culture.Pre-patina, blue-grey zinc is proposed for its environmental friendliness as a 100% recyclable material and its flexibility in cladding the curved geometry.The interior is made of maple wood like a great violin and provides ideal acoustics.Sound-absorbing scratch coat plaster and raw crinkled concrete complement the experience at the gathering spaces.

The glass walls and skylights infuse the building with natural light and lessen reliance on nonrenewable energy.Visitors are embraced within a light-filled environment that changes organically during the day and seasons.Skylights increase ambiance during the day and illuminate at night when the building glows from within and casts light to the Esplanade and the park.
