A Bridge for Joy and Discovery

In a time of increased disconnection between urban communities brought on by the Covid-19 pandemic, meaningful and sustainable urban living environments are vital to building stronger social connections and wellbeing in community. Individual and social wellbeing flourish when the stage for community networks is set and strengthened.

Sustainability is not just about low impact infrastructure and using lower carbon modes of transport. Designers who adopt a multi-dimensional view of sustainability can create solutions to mitigate complex problems brought on by demographic shifts to support communities through changing social needs and reduce the impact of social alienation on people and their environment.

In Singapore, where 80 percent of the population live in public housing flats, these very homes and their urban surroundings support people’s essential physical and emotional needs. Thus, designing for social sustainability crucially requires the understanding and balancing the diverse needs of stakeholders. Socially sustainable environments are enabling, physically flexible, and inclusive.

Transit-oriented developments such as EastLink I & II Canberra, play a vital role as transit hubs in connecting the residential heartlands of Singapore to the rest of the city. Recently completed in 2020, this residential development connects two plots of Housing & Development Board BTO (Built-to-order) flats to the Canberra MRT station, and integrates with a new-generation neighbourhood centre consisting of commercial and community facilities.

EastLink I comprises six residential blocks ranging from 11 to 12 storeys, while EastLink II consists of five 11-storey residential blocks. The three-storey Canberra Plaza neighbourhood centre serves as a one-stop destination. Its facilities include an event plaza, a water play park, pockets of greenery, and a wide range of commercial, retail, medical, and educational programmes.

Drawing inspiration from nature and history

The estate of Canberra, in the northern region of Singapore, close to the forested coastline, historic Sembawang Shipyard, and the old British naval base, is steeped in rich nature and naval heritage. Sited between the boundaries of two water bodies – the Straits of Johore and the Upper Seletar Reservoir – the architectural language of EastLink I & II draws inspiration from the movement of flowing rivers. This flow is articulated in elevation through the undulating bands of the residential building precast façades and the circulation of people transitioning along the central urban spine, from ground pedestrian routes to elevated shared public spaces.

Building bridges for new communities and active mobility

A Social Urban Spine
Many young families have recently sunk roots in the relatively new estate of Canberra. The design brief of a family-centric, appealing and liveable public housing precinct and neighbourhood development addresses the needs of this demographic group.

Many young families have recently sunk roots in the relatively new estate of Canberra. The design brief of a family-centric, appealing and liveable public housing precinct and neighbourhood development addresses the needs of this demographic group.

An articulated bridge – the prominent elevated 360-metre long central urban spine – weaves through the two plots and connects the whole precinct, offering a direct sheltered walking experience from every home to the MRT station. A haven of elevated shared spaces, community roof gardens, garden pockets, activity nodes, connected walkways and viewing decks extends from the urban spine, separating pedestrians from ground-level street traffic. Unlike the typical HDB estate ground floor planning driven by myriad service and vehicular drop-off requirements, the elevated urban spine is reclaimed for an urban pedestrian street.

The strong visual and wayfinding concept of the urban connectivity incorporated into the design of the main spine provides strong visual identity and orientation for residents. Pockets of activity nodes, stitched into the urban spine, offer areas for people to discover and for greenery to thrive. These include the roof gardens and shops within the community plaza itself.

To promote active mobility, wide pathways allow for the movement of less-ambulant members of the community. Such inclusive and universally accessible design greatly enables vibrant community life. The fully walkable precinct provides 24-hour unrestricted pedestrian access for all.

The Family Lounge occupies a modest 57 sqm space and comprises a café and zones for reading, working or mingling. It is an inclusive public space where shoppers and residents can use without charges during mall operating hours. It will also be available for booking for private gatherings.

To help new and growing social enterprises and inclusive-hiring businesses with spaces for operations in our heartland shops, HDB had worked with raiSE (1) to identify a suitable social enterprise, Foreword Coffee Roasters, that can operate the café in the family lounge.

As a social enterprise, the café employs persons with disabilities and special needs, and operates on the vision of creating a sustainable value chain. The public-private stakeholder collaboration within this space echoes the equitable and sustainable practices of the selected enterprise.

Biophilic environmental design features
Referencing the area’s natural heritage and water boundaries, the landscape incorporates multi-level “green lungs” that “breathe” in tandem with the stepped façade of neighbourhood centre. This greenery profile allows deep verandahs that help to reduce heat gain in the internal spaces, complementing the idea of lifestyle along the waterway. Riverine-themed tree species and colourful flowering plants create highlights and identity in the landscape.

Subtle site level changes are designed as terraces with functional decks and lush greenery. The design also integrates barrier- free access with the experience of flowing across the landscaped terraces. These internal linkways through the precinct will eventually connect to the island-wide park connector network (PCN). This effectively integrates the area with the city’s active mobility vision for walking and cycling on an urban scale.

Why Social Sustainability Matters
Social sustainability is closely related to the vibrancy of place as people are invariably attracted to bustling and welcoming spaces. The EastLink development design strategy places great value on community and enhancing inclusivity. By honouring the heritage of the site in its design, the development builds upon the distinctive character of the area, and allows new memories to be layered upon, thereby enriching its sense of place.

As a sub-regional transit-oriented development, the EastLink project enhances convenience and connectivity to the rest of the city. This creates social and economic value for the community and stakeholders, and in turns helps the city and its people to thrive.
