Beijing Dayuncun Office Tower Lobby Renovation – Revitalized Fiction
原貌: 零散、缺乏识别性 (Before: Fragmented, Lack of Identity)
The project is located in an office building that was constructed in the late 90s. The exterior canopy part is situated on a conspicuous location right next to a cross-road which is well-known within the local area. Renovation task and challenges we met including the following:
The rustic appearance of the original canopy and lobby does not meet the visual quality required by the client. The Client wish to imply the idea of “Star & Galaxy” in order to reflect the technological and creative ethos of the firm.
Due to the original structural configuration of the existing building, there are quite a few constrains. Existing column grid is very dense, four thick and dense base column situated right in the centre of the lobby will have negative impact on both visual appearance and plan layout.
The interior and exterior part of the project lack connection and unity. To make matter worse is that there are many scattered elements such as signs and mechanical installations on the street, had made the appearance of this area even more chaotic, hence the lack of identity.
愿景：集成、激活（Vision: Integrate & Activation）
Due to above-mentioned issues, our design seek to transform the very nature of this lobby, from pure reception and transient space to a multi-functional hub that will contain a variety of merging programmes. In the same time, the design will derive inspiration from the abstract concept of “Star and Ocean” and had realized it into tangible architectural form.
Our design seeks to create a fusion space that will include programmes such as interaction, exhibition, leisure and reception space. In addition, it will challenge the conventional understanding of division and boundaries, through creating fluid connection between different sectors within the space. Finally, unique design language with futuristic essence will extend into the exterior of the building, and revitalize the local area through its visual identity.
过程与挑战（Development & Challenges）
There are three main limitation caused by the existing structural system:
Columns situated in the central part of the lobby had form visual barrier that prevent viewer to gain proper impression of the overall space, as if the lobby space is segregated into few parts.
Orientation of the original lobby is rather peculiar due to the configuration of existing column and shear force wall, visitor circulation had to do an abrupt turn and enter the lift lobby from a very strange direction. Thus lack the sequence and spatial hierachy for visitor to navigate through the lobby.
Another major limitation is the difference in height between inside and outside. Originally the canopy structure was suspended at a height of 4.9m. This is because of a proportion control with the overall building, as well as it needs a certain distance away from the ground to gain visual attention from the streets. On the other hand, due to many already operating pipes in the ceiling, the interior clearance can only reach 3.3m at the most. This dis-junction between inner and outer had caused much difficulties for the design to bridge the design quality of the lobby and canopy, as the architectural form has to deal with the significant height difference between in and out.
形态融合（Integration of Form）
Using the shape of cloud as a source of inspiration, columns, walls and ceiling will infiltrate and extend into each other through the use of arches and curves. so tectonic elements that would conventionally be segregated would be systematically organized and blended into one unity, like an interactive interface.
功能融合（Integration of Programme）
设计将原有的学术报告厅去除的同时增添了展示空间和小型办公室。新的设计并没有固化地将大厅内的各类功能进行物理分割。而是通过地面材质的划分以及灯带等元素，形成了流动的空间(Circulation Space)和停留式的空间（Habitation Space）之间的“非确定边界”（Indefinite Threshold）。小型办公室和维护间等辅助功能布置在外围，大厅的接待，过道和展示功能则是通过这些“非确定边界”有序地融合成一个整体。在不同的时间段，可以根据不同事件和场景使用需求相互延伸。
The brief require us to remove the original lecture hall situated on the west side and add small offices and exhibition space. New design will not separate these different programme with physical barriers but integrate them into acontinuous interface. Subordinate functions will be placed on the outer perimeter, and indefinite threshold between circulation and habitation space will be formed through the use of different flooring material and light strips. Thus exhibition, reception and circulation may be integrate into a systematic whole, and different functions may blend and merge into each other according to various use and event.
动线融合（Integration of Movement）
A parametric designed “lighting matrix” are implemented as a reflection to the idea of “star and ocean” raised by the client. The matrix is aggregated by a large number of hexagonal lights that varies in four different sizes with the dimensions of 250㎜,200㎜,150㎜,100㎜. The positioning of these lights is based on the intensity of activities and functional requirements of different areas within the lobby. However in the meantime this way of positioning would also generate a sense flow that will guide, converge and influence the pedestrian circulation. What’s more, is that this design feature in its singular hexagonal shape will be read an unifying icon that forms the linkage between different areas such as reception and exhibition, but collectively it will then become a shape-shifting element which will enrich the visitor’s spatial experience as they move across the lobby.
Dynamic curved features, resonating with special lighting effect created by the light matrix, as a result of their combined reaction has created cinematic scene very much like science fiction. During various time of the day, the dynamic profile of the space will be rendered differently, and visitors will thus gain an ever-changing experience as they journey through the lobby in their daily routine.
材质融合（Integration of Material）
常规建筑设计中，设计都意图强化不同材质的特性，比如石材和混凝土就应该表现出厚重感，金属是轻盈而玻璃则是通透。本项目中，设计师则是希望弱化这种材质上的差异性，体现材料的非物质化(Immateriality)。目的一是强化科幻现实的体验，二是希望体现当今高新科技产品不断追求的简洁和一体感。设计在技术上探索了材质的可塑性边界，用同一套曲面形式语言去控制不同属性的材料，将GRG(Glass Fibre Reinforced Gypsum纤维增强石膏）、 GRC(Glass Fibre Reinforced Concrete纤维增强混凝土）、石材、铝板、人造石等具有不同物质属性的材料都归纳整合进一个浑然一体的建构系统中，通过材质与造型的融合，呼应“集成、激活”的设计愿景。
Conventional design method often seek to emphasize the difference in nature between material types, such as the bulkiness of concrete, porosity of glass and the light-weight essence created by the texture of aluminium. In this project, our design had approached the discussion from a different perspective and the design process had allow us to explore the limits of, as well as the possible interactive relationship between different materials. As a result of our study, we managed to achieve something that reverse the logic of the conventional material setup, which is, despite the differences between various material such as GRG(Glass Fibre Reinforced Gypsum), marble, aluminium and artificial stone, they will be integrate into one unifying system, through the use of consistent formal language. As a result, the integration of material and form will reflect the key concept of “ Integrate and Activation.”
