Appreciation towards GLA Design for providing the following description:

西溪深蓝作为新型孵化类办公建筑，位于杭州城西科创大走廊紫金港科技城内。设计师将用户需求作为原动力，结合场地环境，用极简的空间设计语言，向人们发出邀请：这不仅是一个纯粹的办公场所，也是开放、包容、多元的文化场所，承载着社交、娱乐、生活、学习等多重可能。

Deep Blue, as a new incubator office building, is located in the Zijingang Science and Technology City of Hangzhou Chengxi Sci-tech Innovation Corridor. The designer takes the user needs as the driving force, combines the site environment, and sends invitations to people with the minimalist space design language: this is not only a pure office space, but also an open, inclusive and diversified cultural place, which bears multiple possibilities such as social interaction, entertainment, life and learning.

孵化“X”场所
CREATE “X”

项目场地相对方正，西侧为清幽河道，三面毗邻不同类型、高度的办公建筑。作为二次委托设计，整体用地较为紧张，建筑密度也不得突破原方案。在充分考虑到平衡孵化类办公建筑的空间需求与心理需求的设计愿景，采用了独立办公空间和共享开放区域相结合的方式。独立工作空间向外，保证一定私密性；开放区域向内，形成一个更有利于交流共享的空间。

The project site is relatively square, with a quiet river in the west side and office buildings of different types and heights on three sides. As a secondary commissioned design, the overall land use is relatively tight, and the building density is not allowed to break through the original scheme. While fully considering the design vision of balancing the spatial and psychological needs of incubator office buildings, the method of combining independent office space with shared open area is adopted. The independent office space is outward to ensure certain privacy; the shared open area is inward to form a space more conducive to communication and sharing.

为了尽可能利用自然采光、通风及景观绿化，在分析城市空间和基地流线后，依据斜穿方形（东北-西南）的对角线，将建筑形体斜向切割3次：东北角主入口斜切面、西南面上层退台斜切面以及下层贯通内部中庭和河道景观的灰空间斜切面。纯粹的几何体切割，使建筑较好的融合了整个城市界面，同时X形的聚合立面又保持了新型办公建筑的独立性格。

To make the best use of natural lighting, ventilation and landscape greening, after analyzing the urban space and the streamline of the site, the architectural form is cut three times diagonally according to the diagonal of the square (northeast-southwest): the oblique section of the main entrance at the northeast corner, the oblique section of the upper set-back terrace at the southwest, and the oblique section of the gray space that runs through the internal atrium and river landscape at the lower layer. The pure geometric cutting enables the building to better integrate with the whole city interface, while the X-shaped converging facade maintains the independent character of the new office building.

可持续策略
Sustainability Strategy

设计师在前期调研中细致地观察了场地不同时段的日照，兼顾考虑到杭州夏、冬两季的季风主导风向。在环境可持续表达上，西南角上下两组开口显著增强了大楼的内院的自然通风效果，提升舒适性的同时节能环保。河道景观顺着小广场景观被引入中庭、层层退台及室内，视觉上将建筑内的空间与周围的自然联系起来，从而形成“滨河绿谷——地面绿带——中心庭院——景观露台”的立体化景观。

The designer carefully observed the sunshine of the site in different periods in the early investigation, and also took into account the dominant wind direction of the monsoon in summer and winter in Hangzhou. In terms of environmental sustainability, the upper and lower sets of openings at the southwest corner significantly enhanced the natural ventilation effect of the inner courtyard of the building, which improves comfort while ensuring energy conservation and environmental protection. The river landscape is introduced into the atrium, set-back terrace and interiors along the small square landscape, which visually connects the space inside the building with the surrounding nature, thus forming a three-dimensional landscape of “riverside green valley – ground green belt – central courtyard – landscape terrace”.

另一方面，东北侧斜切退让出的入口前场，为园区界面增加友好交流的空间的同时，邀请并引导着人们进入室内共享空间，一眼可瞥见的中庭水系和不远处的河道景观，迷人的光影、攒动的身影，打破了建筑、自然与城市的界限。空间分享是社会可持续策略的初衷。

In addition, the entrance forecourt obtained by inclined cutting at the northeast not only increases the space for friendly communication for the park interface, but also invites and guides people to enter the indoor shared space. The visible atrium water system and the river landscape not far away, as well as the charming light and shadow, crowded figures break the boundary between architecture, nature and city. Spatial sharing is the original intention of social sustainability strategy.

模块化体系
Modular System

办公单元设计为三种办公模块，具有统一的4.2m面宽、4.75m层高和不同进深，每个办公模块4.75m层高给客户提供了更多内部可变空间的可能。这些办公模块依靠单边走道或者内走道组合在一起，顺应X的造型结合空调机位，设计分别采用斜向幕墙单元和正交幕墙单元两种幕墙单元，创造出独特、干净的立面。

The office unit is designed into three kinds of office modules, which have the uniform 4.2m face width, 4.75m floor height and different depths. The 4.75m floor height of each office module provides customers with the possibility of more internal variable space. These office modules are combined by unilateral walkways or inner walkways, conforming to the X shape and combining with the air-condition position. The diagonal curtain wall unit and orthogonal curtain wall unit are adopted in the design, to create a unique and clean facade.

悬挑的艺术
Art of overhanging

为了实现X形的建筑形体效果，结构迎来29.4m的巨大悬挑挑战：多项抗震超限情况属于特别不规则结构。设计团队经多方讨论，采用钢框架+中心支撑-钢板组合剪力墙/钢骨混凝土剪力墙的混合结构体系，悬挑部分采用钢桁架加斜支撑，最终实现了设想的建筑形态。

To realize the X-shaped building form effect, the structure has the challenge of a huge cantilever of 29.4m: A number of seismic overruns belong to special irregular structures. After many discussions, the design team adopted a hybrid structural system of steel frame+center support-steel plate composite shear wall/steel reinforced concrete shear wall, and the steel truss with diagonal bracing was employed for the cantilever part, finally realizing the envisaged architectural form.

出于对环境的保护及成本的考虑，二次委托中的结构设计在安全的前提下，一方面尽可能对原桩基合理利用，一方面对原地下室楼板结构“一拆一利用”。

For environmental protection and cost consideration, in the structural design of the secondary commission, while ensuring safety, the original pile foundation should be used rationally as far as possible, and the original basement floor structure should be utilized after demolished.

材料的温度
Material Selection

材料的选择是整个建筑效果完美呈现的关键所在。铝板采用了阳极氧化工艺，配合三层中空Low-E超白玻璃，为建筑提供了高效的保温节能功能。在立面效果上呈现简洁、统一的形态，也为室内外的空间提供了透明且有效的连接。

Selection of materials is the key to the perfect presentation of the overall architectural effect. Anodizing process is adopted for the aluminum plate, which is combined with three-layer hollow Low-E ultra-white glass to provide efficient thermal insulation and energy saving functions for the building. The facade is simple and unified, offering a transparent and effective connection for indoor and outdoor spaces.
