As towers of glass, steel and concrete start forming the skyline of the Northern Metropolis, a swath of green the length of the development is being maintained to protect the wildlife inhabiting the area for more than a century.
The Northern Metropolis (NM) development is a futuristic university city, occupying one third of Hong Kong’s land mass along Shenzhen River boundary with the mainland. Catering for a new population of 2.5 million and offering 65, 000 jobs with additional transport links, the project is expected to reach it potential in 2036.
In addition to the residential development, the plan includes an extension of the existing logistics hub in the Hung Shui Kiu and Ha Tsuen areas. And two eco-tourism nodes will be established in the coastal areas of Tsim Bei Tsui and Pak Nai, featuring resorts, weekend markets, and camping sites. Authorities have expressed their intention to create a coastal protection park along the 10.7-km coastline.
However, it is being built on what was previously fish farms, agricultural land, marshes and mangroves – wetlands, a natural habitat for wildlife and an important foraging ground and habitat for migratory water birds.
The plan was launched as a proactive conservation policy in the Chief Executive’s annual policy address in 2021 and has gone through various consultation exercises involving surveyors, conservationists, property holders and the public.
The wetland conservation system is estimated to have a total area of about 2 000 hectares (ha). This includes the existing Hong Kong Wetland Park (HKWP) at Tin Shiu Wai (about 62 ha) plus an expansion of about 240 ha, the Mai Po Nature Reserve (about 370 ha), the proposed establishment of three Wetland Conservation Parks (WCPs) at Nam Sang Wai (about 400 ha), Sam Po Shue (about 520 ha) and Hoo Hok Wai (about 300 ha), as well as the establishment of Sha Ling/Nam Hang Nature Park (about 4 ha) and Tsim Bei Tsui/Lau Fau Shan/Pak Nai Coastal Protection Park (about 145 ha).
Indigenous to Hong Kong and southern China is the Eurasian Otter which has been documented in parts of the territory for more than a century with the earliest sighting records dating back to the 1890s. Today, the species is considered locally rare with a restricted distribution, occurring primarily around Mai Po Inner Deep Bay Ramsar Site, with occasional sightings in Lok Ma Chau, Hoo Hok Wai, and Hong Kong Wetland Park. (A Ramsar site is a wetland designated as being of international importance under the Ramsar Convention, a global treaty signed in 1971 in Ramsar, Iran, to protect and sustainably use wetlands).

Access control measures are in place in areas with otter occurrence, such as Mai Po Nature Reserve, the non-visitation area of the Wetland Reserve at HKWP and ecological mitigation wetlands created under development projects, to protect the sensitive habitats and minimize potential disturbance to the wetlands and their associated animals. Separately, under the planned Sam Po Shue Wetland Conservation Park (SPS WCP), enhanced freshwater wetland habitats and ecological passage will be established to allow wildlife, particularly the otters, to travel between the SPS WCP and adjacent wetlands. Additionally, the river channels within the SPS WCP will be enhanced to provide habitats for the otters, with the incorporation of habitat enhancement features such as otter platforms, artificial holts (otter burrows) etc. at appropriate locations in the park.
Reports from the Adelaide Zoo in Australia indicate that otters are not shy (unless threatened) and in fact become more playful in the presence of humans.
Lau Fau Shan oysters were once favored in Hong Kong until the mid-70s when they were subjected to contamination from heavy metals fed into the Shenzhen River further upstream from battery making factories. The loss-making industry is now virtually dead save for about 10 per cent of its former glory being maintained by villagers with purified water systems.
Conservation groups believe the introduction of eco-tourism in the area would help the villagers bring survival back to the industry.
Now, under the NM development plan, a dedicated Coastal Protection Park (CPP) is being established along the Deep Bay coastline, covering Tsim Bei Tsui, Lau Fau Shan, and Pak Nai.
The CPP, spanning about 10 km and covering about 145 ha, aims to protect critical habitats for horseshoe crabs, mangroves, and seagrass beds.
Conservation groups, including The Nature Conservancy, are also actively advocating for Pak Nai, near Lau Fa Shan, to be designated as a formal Marine Protected Area (MPA) to safeguard its status as a biodiversity hotspot.
The government is to be applauded for taking the initiative of blending the eco system in an intense high-rise technical urban sprawl. The government has launched public engagement exercises and invited Expressions of Interest (EOI) for eco-tourism nodes in these areas. The goal is to transform conservation value into economic vitality through guided tours and educational facilities without compromising ecological integrity.

Next month, on September 3, the world will celebrate Skyscraper Day when Hong Kong is expected to be crowned, again, as the city having the most skyscrapers. According to the Chicago-based Council on Vertical Urbanization, Hong Kong has 596 skyscrapers over 150 meters in height.
The city has been forced to build vertically due to its small land area and dense population and its skyline is among the most renowned in the world thanks to its robust financial sector, international trade connections, and creative urban planning.
Following up is Shenzhen with 444 skyscrapers and New York third with 317. The tallest building in the world is the Buri Khalifa in Dubai reach 828 meters and has 163 floors for hotels, residence, offices, observation decks and communication systems.
The council adds that Skyscraper Day is the ideal time to examine which cities have the most skyscrapers and how they represent advancements in economy and design.
Also, the Council on Tall Buildings and Urban Habitat has weighed in noting that when it comes to soaring skylines and architectural marvels, no country has embraced the vertical revolution quite like China. Hong Kong, along with Shenzhen, and Guangzhou (5th position) are part of a burgeoning megacity known as the Greater Bay Area, which is home to over 1,500 skyscrapers. This is even more impressive when considering that Shenzhen, which now boasts a population of 17 million people, was just a small fishing village until the 1970s.
Looking at this data from another perspective, China actually has more skyscrapers than the rest of the world combined. China has 12 cities, 2777 skyscrapers and 72 supertalls (300-599 meters tall) in the top 20, compared to the rest of the world with 13 cities, 2350 skyscrapers and 67 supertalls.
China’s prominence in the world of skyscrapers—with three cities in the top five globally—is likely to remain unchallenged, especially with the expected dominance of high risers in Hong Kong’s Northern Metropolis development, slated for completion in 2036.
In Hong Kong, the tallest building is the 484-meter-tall International Commerce Center which has 108 floors for the Ritz Carlton hotel, offices and retail outlets. It is also the 14th tallest building in the world.
This is followed by Two International Finance Center reaching 415 meters and home to the Hong Kong Monetary Authority which is housed from the 77th to 88th floors of the building. And third on the list is Central Plaza in Wanchai which is 374 meters tall with 78 floors of office space. On the 75th floor is a church – iSEE Church, formerly known as the Sky City Church – which is the tallest church in the world.
But tall buildings bring their own problems, especially with urban planning. In this regard, Hong Kong has long addressed the problem of the "Wall Effect" high risers present and instead has transformed its vast skyline into a global leader in sustainable construction.
The Hong Kong Planning Department has introduced strict Urban Design Guidelines and Sustainable Building Standards to break up the long rows of uniform high-rises. Developers are required to leave wide gaps, known as "breezeways," between tall buildings so that these air corridors enable natural sea breezes to flow through, cooling the streets and dispersing vehicle exhaust.
Also, the collaborative effort between the government and the construction industry has established Hong Kong as an internationally recognized hub for green high-rises. New buildings, for example, are required to allocate between 20 and 30 per cent of their site to green spaces, leading to high-rise developments featuring lush sky gardens, green roofs, and vertical planting walls that help absorb heat.
A classic example of this is The Henderson in Hong Kong’s busy central business district, which ranks it among Asia’s greenest skyscrapers, having achieved a top-tier Platinum certification for its smart, zero-carbon cooling systems and resilient layouts.
The certification process was conferred by the LEED global rankings of sustainable and environmental friendly buildings which placed Hong Kong sixth worldwide (and fourth in Asia) for meeting its strict criteria.
The verticalization of Hong Kong is necessary because of severe shortage of land. About 43 per cent of the total land area falls within the protected areas such as country parks, marine parks, wetland, sites of special scientific interest, and water gathering grounds. These areas are either statutorily protected or highly restricted from development. Development can only go up. But this has also bought a premium on land supply and price.
All land in Hong Kong is owned by the government, except where St John’s Cathedral stands, which was granted a freehold in perpetuity to the Church of England in 1847. The government leases and grants land for ownership for long periods of time, generally about 50 years or more. Land is released for development in a timely manner depending on demand generally through auctions. So for the current quarter, only one piece of land for residential use will be offered for sale in Kowloon to provide for some 250 high-rise flats.
The measured land release comes as Hong Kong’s residential market shows signs of recovery after years of downturn and when the government has lowered its land premium revenue target for the 2026-27 financial year to about HK$18 billion (US$2.3 billion).
For the current quarter, supply would also include more than 3,000 units from the first Northern Metropolis large-scale land disposal project in Hung Shui Kiu. The government aims to award the tender during the next week or so.
The Hung Shui Kiu pilot site marked the first land sale under the government’s new large-scale land disposal model for the Northern Metropolis.
Again, all of the once fertile agricultural and fish pond land in the Northern Metropolis will be transformed into a sea of high rise futuristic buildings to keep Hong Kong at the top of the skyscraper ratings for many years to come.
