臺中歌劇院是位于臺灣中部大城市——臺中市的一座劇院綜合體。該綜合體由三個分別設有2 000席、800席及200席的劇場組成，配有充足的排練室和后臺空間。建筑周邊亦規劃餐館、日常商業設施和停車場。

這是繼“仙臺媒體中心”之后結構系統最復雜的項目。運用轉換抽象的網格幾何體，我們創造了三維曲面——鋼筋混凝土殼狀洞穴式空間。洞穴空間內設有三座劇場，洞穴式空間在水平和垂直方向形成兩組管狀空間。我們稱之為“懸鏈面”。兩層為一組，重復開合。這些層面垂直堆疊構成了建筑結構。

構造系統基于我們未實現的“根特的音樂、舞蹈和藝術文化廣場”項目，但有所不同。在根特項目中，由于城鄉連接緊密，我們采用了可呈現街道網絡的空間設計。建筑正立面為沿建筑場地而建的切面，建筑物內外空間延展性強。臺中歌劇院坐落于擬建公園用地，矩形建筑的四個立面延續仙臺的抽象和獨立之感。內部曲線幾何延伸到外部，形成網狀花園。

各個劇場空間相互獨立，因而需要分隔系統。我們將之稱為“插片”。在三維懸鏈面水平和垂直方向插入二維平面。水平插片相當于地板，如無邊的水面般延伸于懸鏈面空間。根據平面，地板可連續或獨立。垂直插片猶如注滿水的洞穴的斷面，反復出現在立面和截面上。

我們創造洞穴式原始空間，置身其中，人們可以感受有機空間網絡。我們希望臺中歌劇院能夠成為人類情感表達的本源形式——藝術表演的適宜場所。

This is a theater complex planned in Taichung, a metropolis in the central part of Taiwan. The complex includes three theaters with 2000 seats, 800 seats, and 200 seats, with plenty of rehearsal rooms and back spaces. Restaurants and commercial facilities for daily use and park spaces around the building were also planned.

This project has the most complicated structural system since the “Sendai Mediatheque”. We created a huge cave-like space with three-dimensional curved surfaced reinforced concrete shells, which was generated from the transformation of geometries created with simple grids. Housing three theaters in this cave-like space, the space forms two pairs of tubular space in vertical and horizontal directions. We named this structure “Catenoid”.Two layers are combined as a set, and those layers repeatedly open and close. These formations are then stacked vertically to form the structure.

This structural system is based on our unrealized project “Forum for Music, Dance and Visual Culture, Ghent”and yet there are some diあerences. For the Ghent competition, due to the close relationship between the city and the suburbs, a space that represents streets networking was intended. The fa?ade is a cut surface along the site, and the inside of the architecture and its outside had strong continuity. The site of the Taichung Opera House is the proposed park and the four fa?ade surfaces of this rectangle shape have abstract and independent sense as in the case of Sendai. And yet the curved geometry inside has continuity to the outside,which forms the networked garden.

As each theater space needed to be independent, a dividing system is required. We named this system “Plug”, and here two-dimensional surface was plugged in three-dimensional Catenoid surface horizontally and vertically. The horizontal Plug performs its role mostly as a floor and it looks like an extended water surface stretching out within the Catenoidal space. The floor can be continuous or independent depending on the surface level. The vertical Plug can also be considered as a sectioncut of a cube filled with water in the cave and appears on the fa?ade and cross-sectional surface repeatedly.

We created this cave-like primitive space where people can feel the organic spatial network, in hopes that this space can be a suitable place for play performances, the fundamental form of expression for human beings.
