Bio Bio市民剧场坐落在智利康塞普西翁的Biobío河河畔。建筑由Smiljan Radić、Eduardo Castillo与Gabriela Medrano设计，他们在2011年赢得了该项目的竞赛。建筑内部是混凝土网格，外部是半透明的折叠外壳。设计基于波兰剧院导演Tadeusz Kantor的话：“我的包装（packagings）是通过将其隐藏、包裹，来尝试‘预示’物体的本质。”

The Teatro Regional del Bíobío stands on the edge of the Biobío River that runs through the Chilean city. A trio of architects – Radić, Castillo and Medrano – won a competition to design the theatre back in 2011 and it opened earlier this year. A translucent concertinaed shell conceals the gridded concrete interior of this theatre. The architects developed a design with a contrasting interior and exterior appearance, based on a quote by Polish theatre director Tadeusz Kantor: "My packagings were an attempt to 'portend' the nature of the object. By hiding it, enveloping it."

半透明聚四氟乙烯表皮覆盖在混凝土框架之上，创造了这种二元性。Smiljan Radić使用了类似的半透明白色玻璃纤维来设计2014年的蛇形画廊展亭。建筑外立面条带状的横向分割与建筑的六个楼层对应，相邻层的外表皮向相反的方向倾斜，创造出类似手风琴的效果。夜晚，光线透过立面，建筑犹如水边的纸灯笼。

A skin of semi-transparent polytetrafluoroethylene (PTFE) is laid over a regimented concrete framework to create this duality. Radić employed a similarly translucent skin of white fibreglass for the globular Serpentine Gallery Pavilion he created in London in 2014. The covering is applied in bands corresponding with the building's six storeys, with each level tilted in opposing direction to the next to create a concertinaed effect. Light shining through the facade at night lends the form the appearance of a paper lantern on the water's edge.

嵌在聚四氟乙烯上的玻璃有助于白天大堂和交通空间的照明。一个玻璃条带和下面的混凝土骨架在这座9650平方米的建筑下部向外张开，在建筑周围的公共广场上创造了一个有遮蔽的入口。两个剧院和一个排练室被包裹在棕色的镶板中，在混凝土框架中不同高度处悬空。网格在一层形成一个大门厅。外形像切割岩石的多面木质座位点缀着框架中3.9米的空隙，建筑师将框架比作用于支撑舞台道具的脚手架结构。

Sections of glazing set into the PTFE help illuminate lobbies and circulation areas during the day. One band of glazing and the concrete skeleton beneath it splay outwards at the base of the 9,650-square-metre building, creating a sheltered entrance off the public plaza that surrounds it. Two theatres and a rehearsal room encased in brown panelling are suspended at different heights within the concrete frame, while the grid is kept open at ground level to create a large foyer. Faceted timber seats shaped like hewn rocks dot the 3.9-metre gaps in the frame, which the architects compare to the scaffolding structures used to support stage props.

建筑师说道：“在建筑内部，网格几乎占据着空间的每一个角落，观众将在其中移动。”“大厅里的所有这些……只是一个脚手架，一个背景，是通常不被看见的较低级别的支撑结构。”

"Inside, the spectator will move/climb a spatial grid that stubbornly appears to measure/occupy each corner," said a statement from the architects. "All this paraphernalia around the halls [...] is simply a scaffolding, as if it were the backstage part of a scenery, the lower-rank supporting structure that is usually hidden from view."

带有玻璃栏杆的混凝土台阶和一对玻璃升降电梯依附在网格上，而框架中的对角线则被光带所强调。在其中一个剧院里，条形灯在天花板上延续网格的图案。

Flights of concrete steps with glass balustrades and a pair of glazed lifts adhere to the grid, while diagonals in the framework are accentuated by strings of lights. Inside one of the theatres, strip lights continue the gridded pattern onto the ceiling.
