Greenery is present in every HDB estate. It helps to reduce temperatures and mitigate heat while improving air quality and biodiversity, besides being pleasing and attractive. Over the years, through planning, research and innovation, we have studied and developed novel ways of weaving greenery into our estates and towns, reduce temperatures and mitigate heat, while improving air quality and increasing biodiversity.
The Biophilic Town Framework we developed in 2013 is inspired by the concept of “biophilia”. Defined by biologist E.O. Wilson in 1984 as the innate desire for humans to connect with the natural world through 5 key elements of soil, flora and fauna, outdoor comfort, water, and people, it helps our architects to plan the neighbourhood landscape to foster stronger connections with nature so residents can enjoy its intrinsic benefits.
From July 2018, we have progressively applied this framework to new housing projects.
Punggol Northshore will be the first district to adopt the Biophilic Town Framework. Green corridors were strategically planned and placed at Punggol Northshore District to maintain the ecological balance and promote biodiversity
New habitats such as dragonfly ponds are introduced along the green corridors to attract diverse species and boost biodiversity in the area. Trees such as Salix babylonica (Weeping Willow Tree) will be planted to attract the Leopard Butterfly, a species found in the native site through field surveys.
A study of the climatic conditions in Punggol Northshore District was carried out.
As part of our master planning process, we conduct environmental studies to better understand the existing conditions of sites which are near sensitive biodiversity areas. We carefully consider the findings from the studies so that we can sensitively plan the land use and make adjustments to the Master Plan if needed to mitigate the potential impact, and establish urban design strategies to provide a quality living environment.

To overcome limited land space, we have been integrating greenery in unconventional spaces, such as rooftops. Since 2009, all new multi-storey carparks come with roof gardens. A variety of outdoor facilities such as seating corners, fitness stations, and playgrounds decked with lush landscaping make roof gardens a welcoming and tranquil green space for residents.
Roof of Blk 442A Fajar Road has been transformed from a bare space to a green roof through the installation of Prefabricated Extensive Green (PEG) Roof Tray system to mitigate the impact of urbanisation and provide green visual relief in high-rise high density living environments.
An important aspect of landscape design in our estates are facilities encouraging interaction and activity. Lawn spaces for free play, 3-generation playgrounds for multi-generational use, and spaces for community events are examples of spaces where neighbours can bond while immersing in greenery.
Working closely with other agencies, such as NParks and PUB, we integrate blue and green into our public housing landscape for residents to enjoy waterfront living amidst greenery.
Along the banks of the Punggol Waterway, you will find 35 specially cultivated freshwater-tolerant mangrove species. Besides creating a more scenic waterway, the mangrove roots help to bind the soil and stabilise the slopes at the riverbanks. Selected species also improve and restore the coverage of endangered native mangroves in Singapore.
HDB’s patented invention of an interlocking hexagonal floating module system is strong enough to support loads of up to 10,400kg. This innovative floating system introduces more greenery on the surface of the waterway. Together, the mangroves and floating wetlands act as natural water cleansers. Using plant species that could effectively absorb excessive nutrients and pollutants from the water, water quality has improved by up to 30%.
