    2、ssioned the “Urban Design Guidelines for HongKong”(the Study) in early 1998 with a view to preparing a set of guidelines topromote public awareness on design considerations, and to provide a broadframework for urban design assessment.The overall objective of the Study is to promote Hong Kongs image

    3、as a world-class city and to enhance the quality of our built environment in functional andaesthetic terms at both macro and micro scales.The Study covers major topics relating to urban design with special emphasis onthe following which are relevant to the day-to-day work of town planners and relate

    5、ncepts and PrinciplesUrban design is generally accepted as the process of giving design directions tothe relationship of buildings and space in response to social and economic forcesthat impinge upon the city at each stage of its development. In arriving at urbandesign concepts and principles for Ho

    6、ng Kong, it is important first to recognisethat Hong Kong functions within a laissez-faire system, with a small governmentand an established policy of non-intervention. Hong Kong is also not a city withlarge coherent areas of quality architecture. On the other hand, Hong Kong has itsown attributes a

    7、nd development needs. It is therefore necessary that the urbandesign concepts and principles for Hong Kong have to take due considerations ofthe above. Toachieve this objective, it is necessary first to understand the majorfactors that affect physical design context of Hong Kong. These factors inclu

    8、detopography, historical development and the major urban design programmes.The natural context is a fundamental consideration in a citys formation. HongKong comprises very mountainous terrain, many coastlines and a good naturalharbour. This physical context has some important implications. Firstly,

    9、it hasgiven rise to the evolution of our city around both sides of Victoria Harbour againsta dramatic mountain backdrop. Secondly, the steep topography has channelledother urbanisation in various parts of Hong Kong onto flat and reclaimed land withthe mountain ranges providing the natural landscape

    10、background to the urbansettlements. Thirdly, the mountain ranges give Hong Kong a number of distinctviewsheds. Each viewshed develops in different form or density without necessarilyaffecting visual environment in the adjacent viewsheds. Examples to illustrate thecharacter of physical context of Hon

    11、g Kong include the setting of Central andWanchai asviewed from TsimSha Tsui, MaOn Shan New Town against MaOnShan and Sai Kung viewshed, etc.Physical Design Context of Hong KongSai Kung Viewshed Central and WanchaiMa On Shan New TownTopographyUrban Design Guidlines for HongKongUrban Design Guidelines

    12、 for Hong Kong3Geographical distribution of settlements and prevailing built forms add anotherdimension to the design context of Hong Kong. Development in Hong Kong wasbased upon a number of fishing villages and market towns. Then, there was rapiddevelopment in the north shore of Hong Kong Island, K

    13、owloon Peninsula as wellasKwun Tong and Tsuen Wan. With the launching of the New Town Programmes,there were more deliberate and organised patterns of development at various partsof the New Territories. The evolution in the geographical pattern of urbanizationwas accompanied by the changes in built f

    14、orms. In the early years, urban devel-opment consisted of Cantonese, Hakka and Tanka villages of one to two storeys.A need for development in the post war years led to increase in permissible plotratio and higher density developments. Nowadays, there are still needs to developmore high-rise building

    15、s to cater for population pressure and economic growth andalso in recognition of Hong Kongs entrepreneurial spirit.Another dimension that affects the urban design context of Hong Kong is themajor urban design programmes and studies. There have been various urbandesign studies undertaken at both stra

    16、tegic and district levels. The most impor-tant is the Urban Design and Landscape Framework of the Metroplan which pro-vides a visual framework and guidelines for three dimensional design of theurban form of Hong Kong. Because of the extensive consultation during the prepa-ration of the Metroplan, th

    17、e urban design concepts and principles have been welltaken by the community and are useful basis for future direction and approach ofurban design in Hong Kong.Historical DevelopmentMajor Urban Design ProgrammesTaking into account the above, the urban design attributes of Hong Kong can beviewed at th

    18、ree levels:(a)At the macro level is the urban design relationship between the built form(buildings, space and infrastructures) and its natural setting (mountains, waterand green space) which together form the Image of the City. Elementsinclude ridgelines, urban form, harbour, gateways, functional di

    19、stricts, etc.(b)At the intermediate level is the relationship between buildings, buildings tospace, and buildings/space to streets. Attributes include composition ofbuildings, massing and heights, urban architecture, landmarks, open space,linkages, pedestrian networks, view corridors, etc.(c)At the

    20、micro level is the relationship between the users (human beings) andthe built environment. It is concerned with users perception and experienceof people with their daily environment. Attributes include human scale,transition, harmony, street furniture, streetscape and others.Urban design guidelines

    21、should be formulated for enhancement of the above attributesto improve livability and environmental quality of Hong Kong. From the above, theStudy establishes the definition and urban design principles to guide futuredevelopment of Hong Kong.Urban Design Attributes of Hong KongUrban Design Guidlines

    22、 for HongKongUrban Design Guidelines for Hong Kong4 “Urban Design is the use of physical design methods and development processesto create a high quality, sustainable total built environment that respects the spiritof the place and public interest of Hong Kong.”or more appropriate:“Urban design aims

    23、 to enhance the quality of the living conditions in Hong Kongthrough a comprehensive strategy for improving the public realm, urban amenitiesand cultural facilities, improving the quality of development, and ensuring thatdevelopment is suitable for its setting, so as to improve the urban competitive

    24、nessof Hong Kong and to make it a better place in which to live.”Definition of Urban DesignIn this connection, urban design principles for Hong Kong should include:Ensure high quality:One of the key objectives of urban design is toimprove the quality of life by providing a highquality built environm

    25、ent commensurate with thenatural setting.Embrace flexibility:Guidelines of urban design need to be robust andendure over time.Urban Design Concepts and PrinciplesEncourage dynamism:Hong Kongs spirit is based on a pluralism anddynamism, and any guidelines should seek toencourage, not stifle this exci

    26、tement.Toachieve these principles, the Study prepares a collection of commonlyencountered urban design terms/concepts with illustrations in the Hong Kongcontext and overseas. These are contained in Final Report.Based on the foregoing discussions, it is considered that the direction of urbandesign in

    27、 Hong Kong should specifically focus on the basics of urban design, i.e.by striving to ensure a high quality of built environment and providing a high qualityof life.Urban Design Guidlines for HongKongUrban Design Guidelines for Hong Kong5Guidelines on Design IssuesCommonly Encountered in Developmen

    31、nstnoise and air pollution from road traffic. Broad design guidelines were thenformulated on these issues for public consultation. It was commonly agreed thatapart from the issue of preservation of views to ridgelines and achievement of awell-designed waterfront, the guidelines for most of the urban
