KPN鹿特丹总部扩建项目现在已经完工。通过V8设计的新公共入口基座和更新改造的塔楼，建筑加强了位于鹿特丹Wilhelminapier的入口空间。
The expansion of KPN’s head office in Rotterdam has been completed. With V8’s design for a new publicly accessible plinth and the renovation of the tower, the building fundamentally strengthens the entrance of the Wilhelminapier in Rotterdam.

考虑到码头的港口特征，扩建部分被设计成为一个公共的玻璃“航站楼”，塔楼锚固在基座上面。立面与现有塔楼架构联系，围绕着塔楼的玻璃折叠、弯曲、倾斜。在结构上，钢结构与整体成型的混凝土作为饰面构件，增强了扩建部分强有力的外观形象。为了强调钢的使用，V8在钢板中使用了形象突出的柱子。暴露的焊缝和不同结构的柱子确保人们在靠近这个前港口区域时能够感受到建筑简洁大方的特征。V8建筑师在设计中，谨慎地建立与伦佐·皮亚诺原有建筑的联系。建筑师邀请这位意大利建筑师对扩建项目和他原始建筑构思的联系做出评价，伦佐·皮亚诺对此做出好评。新建基座实现了18年前就想要建造的Wilhelminapier入口空间，这也是高层建筑的特点和亮点。
Given the port character of the pier, the expansion has been designed as a publicly accessible glass ‘terminal’, with which the tower is transparently anchored. The façade flirts with the existing pylon, the glass folds and curves around the pylon and follows the tilt of the element. The steel construction and the monolith finished concrete in the structural work are at the same time finishing elements that reinforce the robust appearance of the extension. To emphasize the use of steel, V8 has assembled the image-defining columns from steel sheets. The visible weld seams and different structure of the columns ensure that the somewhat rough character of a building in a former harbor area can also be experienced from close by.The design of V8 architects is carefully related to the original architecture of architect Renzo Piano. The Italian architect was consulted to do justice to the initial intentions of the building. The design was received positively by him. The new plinth ensures the still missing, inviting entrance of the Wilhelminapier, which is known for its high-rise buildings and architectural highlights. What was considered eighteen years ago has now been realized.

建筑内舒适度和技术条件均满足现有要求。V8提出的室内概念侧重于新的工作方式，并以此概念设计了一系列特色空间，如完全采用欧洲橡木建造的中央前台和图书馆。照明灯具也是由V8设计的。项目持续了一年的时间。
In the building, all comfort and technology now meet the current requirements. The interior concept that V8 proposed focuses on the new way of working. Within this, V8 has designed certain specials; the central reception desk and the library, fully materialized in European oak. The design of the lighting fixtures is also designed by V8. The realization of the project took a year.

可持续性特质|Sustainable qualities
在KPN决定将总部常年驻扎在这里以及业主RealIS充满雄心的扩建计划下，V8决定为荷兰现有办公楼向可持续性转型做出贡献。扩建设计充满灵活性，可以轻松应对未来不断变化的希望和需求，确保建筑未来的可持续性。外部立面上的绿色像素照明系统更新为节能、可控和全彩的LED像素灯。基座的立面采用了特殊的三层玻璃，确保建筑节能性。建筑还获得了BREEAM评级为‘Very Good’的竣工证书。
With the decision of KPN for a new multi-year stay and the ambitious expansion plan of building owner RealIS, responsibility has been taken to contribute to a sustainable transition of the existing stock of office buildings in the Netherlands. In addition, the expansion has been designed flexibly to easily respond to changing wishes and requirements in the future. This ensures the future-proofness of the building. The green pixel illumination has been updated to energy-efficient, dimmable and full color LED pixels on the outer façade. For the facade of the plinth, special triple glazing has been used everywhere, which ensures an energy-efficient building. The building has been awarded a BREEAM In Use ‘Very Good’ certificate for completion.
