作為臺北表演藝術中心的「第一立面」，球劇場位於捷運劍潭站正對面,為本案重要的視覺焦點,位在7F的高空，猶如懸浮的星球停靠於方形量體上。

800席的球劇場,主空間的材料有如被浸入油漆桶般,由Panton。646C的淡藍色來統一。部分座位席位於7F主觀眾席和後方的8F至10F黑色包廂區。觀眾席座位在水平和垂直向度均環形分佈，球形的立體配置,將每一個座位席到舞臺中間點的距離大幅拉近,增加觀賞表演的互動性和親密感。

球劇場的結構為雙層球殻構造,觀眾席屬於橢圓形結構，自立方體東面凸伸26米，位於5F至12F之間。內殻裡為觀眾主座位區，內外球殻之間為下方的大廳和主動線路徑、中間層包廂區、以及頂部的劇場懸吊燈光設備區。

球劇場前舞台上方的反音板、以及觀眾席座椅材質和牆壁材料,經過聲學計算,均各具吸音或反射的功能。舞台前區為樂池升降區，劇團可透過調整不同設備的使用模式來滿足舞台劇、傳統戲劇、舞蹈、音樂演出等各類表演的聲學和劇場需求。

透過移動後舞台區的兩道大型隔音門，球劇場舞台區可結合大型排練室成為—個T字型的舞台空間,抑或是雙面觀眾席的配置,增加表演的實驗性和自由度。

The Globe Playhouse facing the Jiantan metro station is the “First Façade”of the Taipei Performing Arts Center and is an important visual focal point ofthe design. The sphere at 7F resembles a planet docking against the cube.

The interior finish of the 800-seat Globe Playhouse is defined by the light blue color of Pantone 646C. The seats are in the main auditorium on 7F and the Balcony Boxes on 8F to 10F. The seats in the audience are organized in response to the spherical surface, minimizing the distance between the stage and each seat. This creates an intimate atmosphere within the theater and facilitates interaction between the performers and the audience.

The structure of the Globe Playhouse is a double-layered spherical shell.The auditorium has an ellipsoidal structure spanning 26 meters from the eastern side of the cube, located between 5F and 12F. The inner shell houses the auditorium. Between the inner and the outer shells are the foyer, the circulation route, the Balcony Boxes, and the technical spaces at the ceiling for lighting facilities.

The reflectors above the stage, the fabrics of the seats, and the wall materials are all acoustic absorbent or reflective. The forestage is the orchestra pit, which can be adjusted to suit the acoustic needs of different types of performances, including stage plays, traditional drama, dance, and musicals. The Globe Playhouse can be combined with the large rehearsal room behind the stage. By moving the two large acoustic panels, the two spaces can form a T-shaped stage, or a performing space with the audience on two sides to enhance the possibilities for experimental works.
