1. A “Work-Live-Play” CBD3

Taking the geographical edge of situating closer to the Hong Kong Island, a CBD3 of 100 ha (including commercial, residential, culture and recreation, open space and mobility-related use) will be located in the eastern part of Island A for providing about 4 million m2 of commercial gross floor area (GFA) to create a CBD for the new era and Hong Kong’s future economic engine matching the national policy of promoting Hong Kong as an international finance and trade centre as well as a node for legal services./p>

With reference to the overseas experience in planning new or transforming existing CBDs in advanced cities in recent years and considering the aspiration of the new generation of young people for work-life balance, the planning of the CBD3 on the artificial islands will adopt an innovative planning concept different from that for traditional CBDs by using urban design and place-making approach to create a quality work-live-play environment for living and working.

The diversified activities and the planning of mixed uses will inject liveliness in the business district and make it another unique and attractive tourist destination for Hong Kong.

Apart from providing commercial spaces and convenient transportation network, land will be reserved in CBD3 for housing, culture, creative arts, fashion and entertainment, popular city sports and facilities related to daily living, as well as a large amount of quality public spaces.

Land outside CBD3 will be also reserved for other economic uses (e.g. creative industries, private medical, private education, tourism, marina club and retail, dining and entertainment).

We will also consider adding cultural tourism of outlying islands such as fisherman's wharf to provide upgrading and transformation opportunities for the local fisheries industry.

2. Seven liveable living communities planned with 15-minute neighbourhood concept

These liveable living communities will be connected by a green mass transit system and separated by blue-green corridors with green waterfront promenade along the shorelines.

Based on the concept of 15-minute neighbourhood, each community will be around 80-100 ha and has a green mass transit station at the centre, with the public transport stations, daily shopping and dining facilities, basic community facilities, open spaces, etc. reasonably distributed within the community.

At the same time, comprehensive pedestrian and cycle track networks will be planned to allow residents to travel by healthy modes such as walking or cycling within 15 minutes from their homes to different destinations to obtain various necessities.

In addition, land will be reserved in each community for large-scale community and recreational facilities and/or economic use(s) with a view to diversifying the employment opportunities and increasing the local employment rate within the community. Overall, there will be about 1 million m2 commercial GFA in the seven communities outside the CBD.

3. Blue-green network for promoting healthy living and biodiversity

A comprehensive blue-green network will be planned on the artificial islands to provide a variety of recreational and sports opportunities for people living and working on the islands and create a diverse range of flora and fauna habitats to enhance biodiversity.

The network comprises the blue-green corridors between living communities, over 20 km of accessible waterfront promenades to encourage water-friendly culture, eco-shorelines, and various local, district and regional open spaces.

In addition, the waters surrounding the artificial islands (including the water channels between islands) are very suitable for marinas and a variety of water sports venues including those for hosting local/international competitions.

4. Adopting smart, green and resilient city strategy

The strategy will cover the following measures to ensure that the developments on the islands could, in the long term, adapt to climate change and facilitate Hong Kong to achieve the carbon neutrality target before 2050.

a. Sustainable Planning and Urban Design

  1. Plan convenient and resilient land use layout
    - Resilient Coastline Design
  2. Enhance environmental performance of buildings and encourage green buildings
    - Consider prevailing wind directions and building orientations to reduce energy consumption
    - Use Modular Integrated Construction method to reduce carbon emissions
    - 15-minute Neighbourhood
  3. Promote urban forestry

b. Integrated SGR Infrastructure System

  1. Adopt “Sponge City” design (including sustainable urban drainage system)
  2. Use renewable energy
  3. Adopt district cooling systems
  4. Construct desalination plant
  5. Construct food waste/sewage sludge anaerobic co-digestion facilities
  6. Construct common utility tunnel

c. Smart Mobility*

  1. Plan comprehensive pedestrian and cycle network
  2. Provide supporting facilities for electric and other new energy vehicles

* Recommended by the Transport Department under the “Traffic and Transport Strategy Study”
