自1847年来，位于公园美景中的的Musis Sacrum音乐厅及其附属建筑就以不同的形式，应对着运营商、城市官方机构和居民短期内的需求。项目内容包含对纪念性建筑的改造和具有长远规划的新扩建部分。扩建建筑内部包含一个大型音乐厅和相关配套设施。

Since 1847 the concert halls of Musis Sacrum and its surroundings had taken on a range of different forms and positions in the park that reflected the short time needs of its operators, city officials and residents. The project consists of a renovation of the existing monument and a new extension with a long-term planning in mind. The extension features a large concert hall and supportive functions.

建筑师将扩建部分设计为一个充满吸引力的透明体量，在优美的环境中与原有历史建筑交相呼应。新大型音乐厅的舞台背后有一面朝向公园景色的巨大玻璃窗，能够为表演提供美丽的自然背景。建筑最独特之处在于这面巨大的玻璃窗可以完全打开作为室外表演空间。不同于原有扩建部分，建筑师将新建多用途音乐厅设计成公园中一个单独的体量，确保设计能够满足Musis Sacrum音乐厅对舞台和空间的需求。

▼舞台背后有面向公园景观的巨大的玻璃窗，可以完全打开作为室外表演空间，a large glass window behind its stage can be opened up to the park andthis huge window can also be opened for outdoor performances

The extension is designed as an inviting and transparent pavilion respectfully complementing the historic building in its beautiful surroundings. The new large concert hall features a large glass window behind its stage that opens up to the park and acts as a botanical backdrop. The unique quality consists of the fact that this huge window can also be opened for outdoor performances. Unlike its existing extension, the new multi-purpose hall is positioned as a separate volume in the park, ensuring that our design gives the Musis Sacrum both the stage and space it deserves.

▼公园美景中的新建建筑，the extension in an attractive park

设计概念来源于Musis Sacrum的核心理念：在自然美景和极佳的声学条件下欣赏表演和音乐。设计灵感清晰地呈现出公园、Musis Sacrum机构和Gelders Philharmonic交响乐团及音乐厅的特征。建筑师力求在多功能性和声学方面达到最佳效果，让Musis Sacrum机构成为所有种类演出和活动的场地，例如从交响乐到流行乐等所有类型的音乐会。

The design draws its origin to the core of the institution that defines Musis Sacrum: to perform and listen to music in excellent acoustical conditions within an attractive green context. The inspiration of the design reflects clearly the character of the Park, the Musis Sacrum Institute and the identity of the Gelders Philharmonic Orchestra and its concert hall. No concessions are made regarding multi-functionality and acoustics, enabling the Musis Sacrum institute to be a home for all kinds of shows and events, ranging from symphony concerts to pop gigs and everything in between.
