该项目是2013年悉尼优秀设计大赛的获胜作品，代表了结合工艺与材质的建筑宣言，创造了尊重周围城市结构丰富历史环境的现代塔楼。
Winner of the City of Sydney Design Excellence Competition in 2013, Arc represents an architectural statement that combines craftsmanship and texture to create a contemporary tower that respects the rich historical context of its surrounding urban fabric.

这组塔楼共26层，带有独特的拱形屋顶花园，是悉尼著名天际线中最新的综合体。两座纤细的塔楼从8层高的砖石裙楼升起，其灵感来自该地区的历史建筑。30万块手工砖巧妙地融入精致的历史环境，在克拉伦斯街和肯特街之间创造出穿越场地的公共连通。塔楼位于斯基特巷，该名称可以追溯至1980年代，它在过去用作水手和士兵的保龄球场。巷道上方，59个鳍状结构沿着建筑向上升起，最终形成有机的皇冠外形，瞬间将该项目同天际线中的其他建筑区分开来，打造出接近天空的曲面屋顶。
A pair of 26-storey towers with a distinctively arched roofscape becomes the latest mixed-use building to join Sydney’s celebrated skyline. The two slim towers rise from an 8-storey masonry podium inspired by the heritage buildings in the area. The 300,000 handcrafted bricks blend seamlessly within the delicate historic context creating a public through-site connection between Clarence and Kent Streets. The name, Skittle Lane, dates to the 1980s and draws its name from its past life as a bowling alley from sailors and soldiers. Above, 59 fins travel up the length of the building culminating in an organic crown feature, instantly distinguishing Arc from the rest of skyline, a curved roof form that celebrates how the tower meets the sky.

项目理念与基地的历史环境有关，设计师仔细地研究了悉尼历史上拱的比例和材质。底座的砖石十分厚重，上部的塔则更加纤细和轻巧。设计师将传统的建造方式带回充满玻璃和金属建筑的现代城市中心，人们对此作出积极的回应。红十字会大楼和安德鲁兄弟仓库位于该项目旁，设计师借鉴二者的砖石构件和独特拱门，在立面引入双重特性，构成了裙楼和塔楼不同的美。在蜿蜒的悉尼港和邻近建筑砖结构的影响下，该项目在材料和细节上呈现出与悉尼过去密切相关的复杂性与真实性。
The concept relates to the historical context of the site. We carefully studied the proportions of the arches and materiality used historically in Sydney. The design has a heavy masonry character at the base, whereas the tower above has a finer, lighter materiality. People have responded to the warmth and use of traditional methods being brought back to a modern city centre where most buildings are glass and metal. Inspired by the masonry component in the significant heritage buildings next door; The Red Cross Building and Andrew Bros Warehouse, and drawing from their characteristic arches, a duality is introduced to the façade and represented by the varied aesthetics of the podium and tower. Informed by the curvilinear nature of Sydney Harbour and the brickwork in neighbouring buildings, the materials and details have a level of intricacy and authenticity that relates strongly to Sydney’s past.

悉尼大部分地区布满平顶建筑，该项目探索了开放屋顶的机会。设计师想要突显悉尼著名的户外生活方式，设计出第一个打破常规的高层住宅。设计师让城市和客户相信，将屋顶用于公共设施比私人公寓更有价值，在构想的城市中，人们可以去往屋顶，建筑可以促进社交和重塑城市环境。屋顶开启了与未来城市可能性的新对话，激活了地平面与天际线。
The majority of the city has flat-topped buildings everywhere. Arc explores an opportunity to open up the rooftop. We designed to celebrate the great outdoor lifestyle that Sydney is famous for, and the first high-rise residential design to break the mould. We convinced the city and our clients that there is more value in using the roof for public amenity instead of private apartments – imagine a city where people can escape to the rooftop, where the architecture facilitates social interaction and the reimagining of the urban environment. The rooftop opens up a new dialogue with what is possible in our future cities activating not only the ground plane but also the sky-plane.

当你到达屋顶时，可以看见以悉尼港为背景的城市景观。弯曲的屋顶拱将你同悉尼港有机而起伏的线条及其绝佳的自然资源联系起来。
When you come up to the Arc rooftop, you can see the Sydney Harbour as a backdrop to the city view. The curved roof arches connect you with the organic and undulating lines of Sydney Harbour and its best natural assets.
