建筑设计：Petr Hajek Architekti
地点：捷克，布拉格（Poupětova 1339/3, 170 00 Prague 7-Holeovice, Czech Republic）
DOX+ 综合体是位于捷克共和国首都布拉格 DOX 当代艺术中心的扩建项目。原本以展区为中心的综合体，扩展出舞蹈、音乐、电影、建筑等特殊区域。 DOX+ 由建筑学院行政楼、实验音乐舞厅和舞蹈排练室三幢建筑组成。从建筑的角度来看，建筑是一个单一的单元，这一原则通过统一的灰色和各部分之间流动的相互联系象征性地表达出来。因此，综合体可以被视为一个单一的结构雕像。
行政区域包括入口门厅、俱乐部和餐厅，为 ARCHIP 建筑学院服务。该建筑是在20世纪70年代原建筑改造

Text description provided by the architects. The DOX+ complex of buildings expands the DOX Contemporary Art Centre in Prague, the Czech Republic. The original complex focusing on exhibition areas was expanded by special areas for dance, music, film and a school of architecture. DOX+ consist of three buildings: administrative with the school of architecture, an experimental music and dance hall and a dance rehearsal room. The buildings are a single unit from the architectural aspect and this principle is symbolically expressed by the unified grey color and fluid interconnection of all parts into one whole. As a result, the complex can be perceived as a single structured statue.
The administrative area, with entrance lobby, club, and restaurant, serves as the ARCHIP school of architecture. This building originated on the basis of a renovation of the original building dating from the 1970s, and the typological arrangement of its inner core and open layout have been preserved. Renovation of the interior respects the materials used at the time the building was constructed (linoleum, wood veneer doors, terrazzo....).
The experimental music and dancehall and dance rehearsal room are cast using béton brut. The reinforced concrete buildings are “clothed” in a soft fa?ade which protects them against freezing or overheating. The insulating wool is covered in a flexible insulating membrane which is anchored to the concrete in the pattern of a regular grid. The fa?ade absorbs residual noise escaping from the hall and reduces the acoustic burden on the residential courtyard. Thanks to the pattern, which is based on furniture upholstery, the halls are reminiscent of two large sofas. An upholstered furniture pattern was chosen for its effectiveness in distributing tensile forces along the surface of the fabric. Enlargement of this pattern had no negative effect on its structural properties and, as a result, the plastic film does not tear in extremely cold weather as it shrinks, and tension is not lost when surface temperatures rise in the sunlight.
The hall has variable acoustics and can be compared to a musical instrument which can be tuned depending on the needs of the specific performance. The rotating three-walled under-ceiling panels and foyers are used for this. The three-walled panels are supported by a sound absorbent, diffuse and reflective surface and can be rotated to modify the acoustic properties of the ceiling, thereby changing the acoustic parameters of the entire hall. In order to extend the fadeout effect, the main hall is surrounded by a ring of foyers which can be used as fadeout chambers in the case of special performances. The addition of these areas to the volume of the main hall results in a significant extension of the fadeout period particularly in the lower frequencies.
The square floor plan also means there was no need to clad the walls in acoustic paneling. The hall has seating for 550 guests and has become famous for its acoustics during its brief existence. It is currently also used as a reference recording studio. The roof of the hall is a grassy meadow used for relaxation, outdoor installations or simply as a place for outdoor performances. There is a suspended bridge over the auditorium for acrobatic dancing. The dance rehearsal room has a floor plan with dimensions identical to the stage in the main hall. It “dances” above the inner courtyard on diagonal columns. The geometry of these columns is not random but avoids the traffic plan and technical installations below the floor tile.
