B30 – Bezuidenhoutseweg 30是2014年卡恩建筑在中央政府房地产部门发起的国际公共与私营 部门合作竞赛（Public Private Partnership - PPP）中的中标方案。团队由 Facilicom 领衔，由 Braaksma & Roos Architectenbureau, Deerns, Pieters Bouwtechniek, RebelGroup 及 KAAN Architecten（卡恩建筑）共同组成。五位特殊用户将入驻该建筑：相互独立的规划部门（CPB ，SCP，PBL)，环境及基础设施理事会(Rli), 和荷兰数据保护局（DPA）。

Originally built in 1917, by the then chief government architect Daniel E.C. Knuttel, as a Ministry during a period of austerity and renovated in 1994 by professor Hans Ruijssenaars, B30 is an imposing structure with a strong, distinct architectural character and it is a Grade 1 listed building in the Netherlands. B30 is located in The Hague city center, alongside the Haagse Bos green space. It stands on Bezuidenhoutseweg, an historical arterial route connecting the Royal Palace Huis ten Bosch and the Dutch Parliament, Het Binnenhof.

        始建于1917年, B30 由当时的政府首席建筑师 Daniel E.C. Knuttel 设计，为财政紧缩时期的外交部办公所用。1994 年由 Hans Ruijssenaars 教授重新设计翻修。B30 是一个具有强烈而独特建筑风格的雄伟结构，它在荷兰被列为一 级保护建筑。它坐落在海牙市中心，邻接海牙森林，矗立在 Bezuidenhoutseweg 街道，一条连接皇家宫殿 Huis ten Bosch 和荷兰国会建筑 Het Binnenhof 的历史性轴线。

KAAN Architecten’s design with its clear layout and architecture transforms the enclosed, hierarchical building – with an atmosphere representative of people’s perception of the State in the early 1900s – into an open, transparent and inviting setting in line with a contemporary and state-of-the-art working environment.

        卡恩建筑用清晰的布局和建筑设计将 B30 本来封闭而等级清晰的空间（一种契合20世纪初人们对国家认知的氛围 ）- 转化成一个开放，透明，邀请性的与时俱进的工作环境。

Thanks to an acute analysis that has mapped the essential qualities of the original design to create an inspired framework, the historic building is seen not as a dead museum piece, but as a vital and sustainable component of the total design. Anchored in its urban setting, broader landscape and historic environment, B30 features an accessible and transparent public ground-floor, including restaurant, café, library, meeting and seminar rooms. All passageways are aligned with each other, creating long sightlines through the building, enhancing contact with the street, woods and gardens, and simplifying orientation and way-finding.

        项目独到深刻的前期调研分析映射了原设计的核心品质，也为随后的设计创造了一个启发性的框架。历史悠久的 建筑不再被视为一个死去的博物馆展品，而是整体设计中至关重要和值得延续的一部分。基于其所在的城市环境 ，广阔的景观和历史背景，B30 底层设立餐厅，咖啡馆，图书馆，会议室和研讨室，公开透明，面向公众。所有 通道都相互对齐，打造了贯穿整座建筑的视觉通廊，加强了建筑内部与外部街道，森林，花园的联系，也简化了 内部的路径。

At the core of the building, a large Atrium becomes the quiet heart of B30. Here, Dutch artist Rob Birza was called upon to design a new mosaic floor pattern, a garden abstraction giving life to an internal landscape that is visually connected with the city forest and the new side gardens.

        建筑的中心是一个开敞的中庭，就像是 B30 静静跳动的心脏。 在这里，荷兰艺术家 Rob Birza 应邀设计了一个新 的马赛克的地板图案。这个抽象的花园图案不仅赋予了内部景观新的生命力，也让它与外部的城市森林和花园有 了视觉上的联系。

Knuttel’s original design has been expanded on both sides: the Seminar Foyer features meeting rooms, seminar rooms, and a sunken auditorium running through the glazed space, while the Work Foyer is characterized by lounge and working areas, an espresso bar and a library. The Foyers’ partitions feature large pivoted glass doors encased by high-gloss aluminum frames opening onto the gardens.

        原建筑师 Knuttel 的设计被扩展到两侧：研讨会门厅设有会议室，研讨室和穿过玻璃前廊的下沉 礼堂，而工作厅则有休息室，工作区，咖啡厅和图书馆。门厅的大型旋转玻璃门，配有高光铝制框架，敞向花园 。

Both Atrium and the Foyers have been covered by a series of daylight shafts that borrow from the ubiquitous original coffered ceilings and take as their design principle a square base topped with triangular glass. These elements have been positioned for an optimal dispersion of sunlight, while preventing overheating by solar radiation.

        中庭和新门厅的天花板都开有天窗，天窗以建筑原有的格子天花板为基础，被设计为正方形底座三角形玻璃封顶 的形态。这些天窗的位置及分布是经过考究，最利于阳光的分配而同时又能避免太阳辐射造成的过热。

The monumental staircase grants access to the magnificent former Minister’s Room on the first floor, while the Atrium visually connects with the four upper floors, which accommodates the workspaces of the various institutions. A new level of offices is situated over the “nave” of the building, and flows into the roof, where the height has been reduced from 30 to 20 metres to bring good scale and proportions to the inner courtyard.

        巨大的楼梯通向宏伟的前任部长房间，站在中庭可以一览四个楼层不同机构的工作空间。新建的一层办公室位于 建筑物的“中殿”，并穿插至屋顶。屋顶高度从原有的30米减少至20米，使得内部庭院有了更舒适的比例。

The façades of the new additions consist of a sandblasted concrete frames filled with stone and a colouring agent that matches the tones of the original building. Moreover, the change in hierarchical relations and the importance of the ground floor has been expressed in the façade by enlarging the windows: the openings have been taken down to the stone plinth of the building, moving the window sills down and lengthening the jambs.

        新添加的立面包括填充了石头的喷砂混凝土火焰和与原始建筑物色调相匹配的着色剂。 此外，通过增大开窗面积 （将窗户延伸至建筑的石头底座，将窗台向下移动并延长了边框）在立面上表达了层次关系的变化，强调了底层 的重要性。

B30 now gives space to contemporary ideas regarding government transparency, seen through the original design. A spatial expression of a shared vision that will inspire curiosity and invite research and debate.

        现在的 B30 既保留了原有设计的品质又在空间组织上体现了政府透明执政的当代理念。这种对共享的空间性表达 将会激发人们的好奇心并引发研究和讨论。
