项目之所以称为“杭州之角”,是因为场地位于西湖景观分析区域中划定的城市核心区的最东北角。人们由周边区域进出市中心都会经过场地,极具昭示性。设计首先面临的问题是如何定义一个城市中心区域的边界;同时还面临如何在
紧张的用地下设计大体量要求的100米高层,又要对周边住宅的影响降至最小,还需遵守西湖景观分析的要求?
The name “Corner of Hangzhou” comes fromthe site location, which is just at the northeast corner of the city centerdefined in the West Lake Landscape Planning. People exit or entry downtownHangzhou will
always pass through the site. The firstchallenge comes as how to deal with the large building mass, with height of100m, in a limited site area. At the same time, the site as in city center asksfor a
landmark, where the building is required tominimize the effect to the surrounding residential communities.
应对这些挑战,设计首先在场地引入对角线切分,将建筑主体设置于场地东北侧,定义了城市中心的转角的四个空间界面指向性:沿着对角线获得了朝向西湖方向的最长的景观面,能够一览无余地望到西湖;面向北侧的城市干道和东侧
的高架桥是两个完整的建筑昭示面,面对快速的车流,建筑以大体量、连续横向线条的方式应对车流的尺度;指向西湖文化广场的是局部出挑的城市露台,为高层内部空间延伸出面向城市公共空间与运河的半户外空间。沿着对角线挤压
的建筑体量,也使建筑对周边住宅的影响降到最小。对角线的方式同样贯穿在流线组织上,从西北到东南的流线串联创意文化入口广场、中心广场与南侧下沉广场,在底层塑造了园林式游走路径的创意文化街区。建筑外立面使用水平向
的连续遮阳百叶,作为造型的同时满足遮阳需求。遮阳百叶在立面根据室内的休闲、绿植等公共空间局部“掀开”翻起,朝向城市打开远眺的视线。
To cope with these challenges, the designintroduces a diagonal axis into the site and locates the building to thenortheastern corner. The four sides of the building define the corner of urbancenter with
four spatial directions. The south sidealong with the diagonal axis gets the longest face towards the beautiful lakeview. The northern and eastern sides are two complete volumes facing heavytraffic with
big scale surfaces subdivided by horizontalshade louvers. The side pointing to the West Lake Cultural Square is partialoverhangs balcony and terrace. The semi-outdoor space extends interior viewsand
actives towards the city public space ofcanal and square. The building volume is compressed along the diagonal axis tominimize its impact on the surrounding residential area. The same diagonalstrategy is
used for organizing the circulation. Fromthe northwest to the southeast,the creative & cultural production plaza,the central plaza and the south landscape plaza are connected diagonally, whichis to make a
garden-style creative and cultural districton the ground level. The building facades are covered by horizontal continuouslouvers. They texturelize the form with a smaller scale and shade the summer
sunlight. Part of the louvers, where closeto interior public space, are lifted to ensure a better sight toward the city.
