Abstract: The government of Taichung city has been promoting the urban design system for 20 years. In the past seven years, the government has held the competition of "Urban Space Design Prize" to give positive affirmation to outstanding works under the urban design review to make Taichung city a people-oriented livable garden city. The essence of urban design is to create high-quality urban living space. Its three core strategies are to transform cohesive private space into friendly public resources, the thought of green buildings built on the artificial foundation and the method of urban transitional development. Besides, to realize the strategies, we can track the works that have completed urban design review and won the "Urban Space Design Prize" from 2015 to 2018, discuss how to create street greenbelts by urban design methods such as open space, roof garden, vertical greening and public art, further connect green space systems, and create a park city with architecture and nature existing harmoniously.
Key words: urban design ；garden city ；Urban Space Design Prize
台中市都市设计审议是一个实务且具高度挑战性的都市建设对话平台，由约 20 位委员组成，成员包括都市规划界、景观界、建筑界的代表、不动产及建筑师工会的业界代表及政府部门代表等，共同促成都市发展下环境品质提升的目标，并创造人、生活与都市之间的紧密联系并寻找现代文化的精神。每年审议的重要目标遵循着都市发展的脉络调整，深化现代都市发展的内涵。审议的范围主要有新建的公共建筑、停车场、开发强度与重要度较高的项目，审议的重点包含容积移转、建筑形式与色彩、交通系统、景观与开放空间、植栽绿美化、街道家具、广告布及管理维护计划等。2010 年至 2017 年，都市设计审议平均每年审理 100 余件案例，足见其对于都市空间整体品质的影响性。
都市空间大奖设置目的以奖励“都设空间及设计美学”为主轴，各届的奖项配合都市发展及都市设计审议的策略与趋势调整，鼓励优秀建筑师、景观设计师、开发商、营建商等城市建设相关从业人员，形成一股提升城市环境品质的正向力量。本文分析了 2015 年至 2018 年完成且荣获都市设计空间大奖的作品，聚焦“转变内聚式私人空间为友善公共资产”“人工基盘绿色建筑思维”及“都市过渡性开发手法”三项都市设计核心策略的操作手法及成效。
项目基地属于旧市区的开发项目，基地周围多为高密度、低矮（4 楼左右）且屋龄达 20 年的旧建物。小区主入口面临 30 m 宽的车水马龙的中清路，开放空间留设的尺度受限于骑楼及人行道的连续性与一致性，未能营造足够的绿荫空间。但该项目于基地西侧设置一条供周边邻里穿越的景观小径，串联大面积退缩出的开放空间。一方面，降低建筑量体冲击性；另一方面，提供周边居民驻留及通行的便捷性。这条为提升优质都市空间生活的小径，一侧以绿墙的手法，缓冲并隐藏边侧环境的杂乱；另一侧则善用笔直高耸的落羽松，将狭窄的人行通道以障眼法向空中延伸，巧妙地解决了空间的压迫性，创造了舒适且富有趣味的都市秘径。
在都市设计策略上，该项目以主建物正面自马路边缘缩进 10 m 宽的开放空间及双层安静的绿带空间，对应繁忙且宽 60 m 的市政路，以蜿蜒的街道绿带形式串联至邻近的公园。基地西侧及北侧配置的绿地分别连接邻栋“诚臻邸”与后侧“心臻邸”的绿意，创造了都市街道公园化的可能性。设计师以其对环境与空间质量的坚持，再次转变内聚式私人空间为人本的公共性资产，谦让的空间设计思维营造了建筑与自然对话的机会，也让建筑物名副其实地融入城市绿地舞台中；绿意盎然的复层植栽提供了丰富多样的生态栖地，虫鸣鸟叫的声音为都市注入了活力，增添了繁忙生活的悠闲风韵；垂直绿化的完整性、街道家具的艺术性、公共艺术的绿化性都是本案的亮点，开创了宜居花园城市的契机（图3～5）。

纵观全球都市发展脉络，19 世纪英国的 Birkenhead Park 和美国纽约的 Central Park 都是以面状公园提升城市环境质量，促进周边地产价值提升的典范。然而随着社会价值与环境的变迁及科学技术的进步，面状及带状公园的设计思维已无法满足城市发展与使用者的需求。面对当代公园定位与更新改造的时刻，从业者更应该从城市的宏观思维出发考虑，对应都市设计政策与绿地系统发展的综合考虑，不能孤立或偏颇思考。人工基盘绿化、垂直及屋顶绿化和开放空间的绿化与友善化，都是创造城市公园的必要手段。都市是文化的容器，公园的绿地除了提升环境的质量，对于区域经济与人文活动的激活都起到了很大的作用，可以体现出都市生活的文化灵魂，实现宜居城市的愿景。

The main purpose of urban design is to create high-quality urban life. Taichung City regards itself as a cultural city . In recent years, the government of Taichung City has committed to building the city into a people-oriented livable garden city. Moreover, due to the global thinking of sustainability and ecology, the government of Taichung City has promoted the trend of urban parks. As everyone knows that the government of Taichung City has held the "Urban Design Space Award" for many years in succession, giving recognition to outstanding urban design works. Taichung City Urban Design Review is a practical and highly challenging dialogue platform for urban construction. It consists of about 20 members, including academic representatives from the urban planning, landscape, architecture, industry representatives from the real estate and architect labor union, and representatives of government departments, etc. To jointly promote the goal of environmental quality improvement under the urban development, and to create the spirit of people, life, city and search for modern culture . The important goals reviewed each year will be adjusted to the context of urban development and deepen the connotation of modern urban development. The scope of review mainly includes newly-built public buildings, parking lots, and development cases with high development intensity and importance. The focus of review includes volume transfer, type and color of construction, transportation system, landscape and open space, planting trees and city beautification, street furniture, advertising cloth, management and maintenance plan, etc. From 2010 to 2017, more than 100 cases on average were dealt each year, which shows its impact on the overall quality of urban space.
The setting purpose of the "Urban Space Design Prize" is to mainly reward "Urban Design Space and Design Aesthetics". The prizes of each competition are adjusted to the urban development and strategies and trend of urban design review, encourage outstanding architects, landscape designers, developers, builders and other urban construction-related professionals, and form a positive force to improve the quality of urban environment. This paper analyzes the works completed from 2015 to 2018 and won the "Urban Space Design Prize", and focuses on the operation methods and effects of the three core urban design strategies of "transforming cohesive private space into friendly public assets", "the thought of green buildings built on the artificial foundation" and "the method of urban transitional development".
1 Transform Cohesive Private Space into Friendly Public Assets
The project base is a development project in the old urban area. The base is mostly surrounded by high-density, low (around the height of four floors) old buildings with a housing age of 20 years. The main entrance of the housing estate is a 30-meter busy and crowded road called Zhongqing Road. The scale of the open space is limited by the continuity and consistency of the overhead arcade and sidewalk, and it fails to create enough shade of trees. However, in this case, a landscape path is constructed on the west side of the base for the neighboring residents to pass through, connecting with the greatly reduced open space. On the one hand, it can reduce the impact of the building structure, and on the other hand, it can provide the convenience for the neighboring residents to stay and pass. This path improves the quality of urban living space, by building a green wall on one side to buffer and hide the clutter of the side environment, while on the other side, it distracts attention by making good use of the straight and towering swamp cypress to extend the narrow pedestrian passage into the air, skillfully solving the tension brought by the narrow space and creating a comfortable and interesting urban secret path .
Researchers once lived in Beijing for a period of time, and I missed the milk of human kindness of walking in Hutongs, which made me feel at home. People's memory of the place will form feelings, identification and attachment. In this case, the design of the path did not exist since it was blocked by the landscape pool and people could not pass through it continuously. Therefore, during the review of urban design, the members jointly decided that the path should be constructed to provide convenience and friendliness of the transportation links for the surrounding residents, and the open space allocated by the residence should be turned into public resources. This path is very narrow, but through landscape design, vertical planting and marble mirror reflection are applied to create a quiet space suitable for pedestrians to pass.
1.2 Longbaoqianzhen Residence
In the urban design strategy, the project constructs the length of 10-meter open space and double-layer green belt space to gracefully face the busy municipal road with a width of 60-meter, and connect to the adjacent parks in the form of a meandering green belt. The green space on the west and north sides of the base connects with the green space of the adjacent "Chengzhen Residence" and the "Xinzhen Residence" on the back respectively, creating the possibility of urban streets becoming parks. With its insistence on friendly environment and space quality, the design team has once again transformed cohesive private space into people-oriented public assets. The humble space design thinking has created an opportunity for architecture and nature to exist harmoniously, and has also allowed the buildings to truly blend into the urban green space stage. The double-layer planting in full of green has provided rich and diverse ecological habitats. The sound of insects and songbirds has injected vitality into the city and added the leisurely charm to busy life. The integrality of vertical greening, the artistry of street furniture and the greening of public art are the highlights of this case, creating an opportunity for a livable garden city.
2 The Thought of Green Buildings Built on the Artificial Foundation
2.1 Dawn Campus of Four Seasons Art Kindergarten
The Four Seasons Art Kindergarten is a very famous art education kindergarten. The architect in this case is one of Taiwan's representative architects of green architecture. Facing the artificial foundation of urban development, a large number of greening strategies are adopted to create the possibility of nature and buildings existing harmoniously in artificial buildings. The balcony greening of each floor adopts the method of lowering plate, which reduces the height of the edge of the planting groove, improves the chance of direct contact between children and green plants, and also extends the visual link between users and the external urban landscape, thus successfully creating a natural ecology on the artificial foundation. In addition, the same method is also applied to the floor design of the pedestrian space and horizontal space on the first floor, which makes the greening containers flush with the pedestrian pavement, makes the pedestrian traffic more convenient and comfortable, and makes the green space system more complete.
2.2 Longbaoyuzhen Residence
In this case, the building structure is concentrated from the outer boundary of the base to the center and adopts the lowest building coverage ratio, thus preserving a large number of opportunities for connecting green space with the surrounding sidewalks, open spaces and parks. The real and virtual space misplacement between the buildings and the green space makes the external green plants as the view of the internal space of the buildings. Large-scale public art shows the self-explanatory nature of the entrance. Street furniture and sculpture are amazingly integrated into the environment. Looking up, the artistic form of the exterior wall of the buildings with the beautiful vertical greening of the balconies of various floors, and the blue sky contrast finely with each other. The porous and diverse planting and material selection have created a living habitat and vibrant scenery. In the past, high-rise buildings only enjoyed the right to see the ground from high altitude. With the improvement of vertical greening and roof garden thinking, users can get the experience like being in a park at home.
In this case, the residents on each floor have private balconies. With the design concept of a large number of double-layer plants planting, the plants in containers match with multi-layer shrubs of four seasons and perennial flowers and plants. The greening is connected in series from the first-floor courtyard upwards to the landscape terraces of vertical floors, up to the roof sky garden. Each family grows favorite flowers, plants and fruits, showing natural beauty from every detail. The positive attitude of developers and designers towards the friendly environment and continuous maintenance and management is the key to the successful demonstration of turning the residence into a park in this case.
3 Urban Transitional Land Development
3.1 The Wing Chun Section Constructed by Huiyu Construction
Private land waiting to be developed in the city often exists in the urban environment as abandoned, idle and isolated. This case is called "Granary of Building Materials". The construction company has injected the spirit of "granary" into the developer's concept of "maintaining land". The designer makes use of the base's own soil excavation and filling and the adjustment of earthwork of other construction projects to create topographic and spatial changes in water areas and hills, and then places plants and landscape stones to be applied in a design way to create a visual focus. The pavement of the pedestrian moving line and the overlooking platform uses the remaining usable materials of the building to create a small leisure environment of the city with the thinking of dynamic logistics and the principle of low cost. In addition, the bamboo fence outside the base sways gently with the wind, and the mutual impact and sound of waterfalls add to the vitality of the city and the expectations of users. This project is a temporary design, which combines some building materials left over from construction, successfully activates the pulsation of urban dynamics, creates certain landscape benefits, and is open for public use and sharing. At the same time, the future use of plants will be planted in the base, and the future use of stone materials will be stored in the base, just like a running warehouse .
3.2 Juhong Waterfront Secret Area
This base is a private land waiting to be developed in the city. The unused space is used simple soil excavation and filling to create the image of a waterfront city, which makes the unused space in the city reborn and become an open space for citizens to use for leisure. More than 80 kinds of tree species such as swamp cypress, beech and soapberry are planted in the base. The Structure of container house is used to construct movable temporary indoor exhibition spaces, ecological pools and landscape works by two artists, Wang Zhenwei and Ren Daxian are set up, and designers create greenery in the city with low impact and easy development methods, thus increasing the vitality and usability of the urban space.
From a comprehensive perspective of the development of global cities, Birkenhead Park in Britain in the 19th century and Central Park in New York in the United States are both examples of planar parks that improve the quality of urban environment and promote the value of surrounding real estate. However, with the changes of social value and environment and the progress of science and technology, the design thinking of planar and belt parks can no longer meet the needs of urban development and users. Facing the moment of positioning and renovation of contemporary parks, professionals should start from the macro-thinking of the city, and should not think in isolation or bias in response to the comprehensive consideration of urban design policies and the system development of green area. Afforesting based on the artificial foundation, vertical and roof greening and friendliness and greening of open space are all necessary means to create urban parks. City is the container of culture. In addition to improving the quality of the environment, the green space in parks has played a great role in the activation of regional economic and cultural activities, reflecting the cultural soul of urban life and implementing the vision of a livable city.
