BIG的新项目Sluishuis坐落于阿姆斯特丹高密度城市与开阔原野的交汇处，环绕基地的大尺度的路桥基础设施与小尺度的住宅街区创造出一个充满矛盾与对立的城市空间。建筑师以欧洲传统庭院式建筑为原型，稍作改动，让这个浮于水面的建筑随着人们观看角度的变化而呈现出不同面貌，从而激活了城市空间。在指向IJ湖的一侧，方形的建筑体量被削去了一角，让建筑内部庭院得以与开阔的水面相连，同时也将明亮的自然光线引入了内部的公寓空间。而在与悬空体量相对、靠近住宅街区的一角，建筑空间如叠水般层层跌落，形成了自然与城市不同空间尺度之间的流畅过渡与衔接。

Located between the dense city and the vast landscapes on the edge of Amsterdam, the new Sluishuis is shaped by its complex surroundings at once close to large infrastructure and to small-scale urban settlements. The classical courtyard building is revitalized by two transformations; it fully embraces the idea of living on the water and appears different from every vantage point. Toward the water the block is lifted up, forming a large opening that brings water from the IJ Lake into the courtyard and brings daylight and views to the complex’s inner apartments. Toward the neighboring urban district the block steps down like a cascade of landscaped terraces, creating a natural transition from cityscape to smallerscale, natural surroundings.

“在20世纪末，我以建筑师的身份在荷兰度过了职业生涯中最愉快的几年，所以能够为这座我深爱的城市设计建筑也算是荣归故里了。我们的建筑就如同一座漂浮在湖面上的城市街区，满足着人们日常生活的所有需求。在与城市相接的一侧，层层跌落的建筑似乎在邀请着人们拾阶而上，俯瞰这座水上街区的全景。而向着湖面的一侧，建筑悬挑，形成了一个拱门般的空间，让船只可以经此进入庭院，停泊在内部的码头处。港口中有建筑，建筑中有港口。”  BIG创始人Bjarke Ingels说道。

“Having spent my formative years as an architect in Holland at the end of the 20th century, it feels like a homecoming to now get to contribute to the architecture of the city that I have loved and admired for so long. Our Sluishuis is conceived as a city block of downtown Amsterdam floating in the IJ Lake, complete with all aspects of city life. Towards the city, the courtyard building kneels down to invite visitors to climb its roof and enjoy the panoramic view of the new neighborhoods on the IJ. Toward the water, the building rises from the river, opening a gigantic gate for ships to enter and dock in the port/yard. A building inside the port, with a port inside the building.” Bjarke Ingels, Founding Partner, BIG.

而在外侧，延绵的水上步道环绕建筑、深入湖面，串联起如群岛般飘浮在水面上的游艇码头、帆船学校、水上花园等公共空间。面向公众开放的阶梯顺着跌落的屋顶台地延绵而上，为人们提供了一个可以俯瞰 IJ湖开阔水面的最佳视角。这道阶梯不仅将吸引着游客与附近居民来此探访，同时塑造了一个立体的社区环境，为居住在不同楼层间的居民创造了一个认识彼此的机会。

A promenade with public programs winds around the building and continues into the water, forming an archipelago of islands with houseboats, a sailing school, and floating gardens. A public passage climbs the cascading terraces of the building, serving as a small rooftop street that eventually loops onto the very top of the building to create a viewing platform over the IJ Lake. The passage will not only create adestination for visitors and neighbors, but will connect the residential units to each other and create a unique three-dimensional community between the residents of the building.

“水与城市的交融让阿姆斯特丹名扬天下。而Sluishuis的设计也继承了这一点，建筑与水相互交融，为居住在IJ湖畔人们的生活模式带来了更多的可能性。” BIG合伙人Andreas Klok Pedersen说道。

“The world famous urban environment of Amsterdam was created by the fusion of water and city. The new Sluishuis is born of the same DNA, merging water and perimeter block and expanding the possibilities for urban lifeforms around the IJ.” Andreas Klok Pedersen, Partner, BIG.

而随着人们的移动，Sluishuis的面貌也不断发生着改变。或如同船弓般倒映着下方的粼粼水光，或如垂直绿色空间般邀请着到访的客人与之互动，或如一个真正与城市相连的街区，无限活力的都市生活让其居民、邻里和生活在阿姆斯特丹的所有人都能尽享其乐。

The silhouette of Sluishuis will change as one moves around the building. At one vantage point it appears as the bow of a ship that reflects the water below; at another a vertical green community that invites visitors to engage directly with it; and finally as a true urban block with street access and city liveliness that is to be enjoyed by residents, neighbors, and the rest of Amsterdam.
