Biophilic design for walkable streets: Health-centred insights for urban action

A revitalised walkable street in Australia, Geelong’s Green Spine in Victoria, featuring tree canopy, bioswales, and wide pedestrian paths. This example illustrates how biophilic design principles and interventions are applied to promote urban health and environmental sustainability. Image source: Victoria State Government (2022).

How can we design walkable streets that promote health through nature?
This scoping review synthesises international and cross-cultural research—drawing from English and Chinese studies—to clarify intervention types and health mechanisms, offering an essential evidence base for healthier, more connected urban environments.

The problem

Urban streets are essential everyday spaces, yet their design often neglects the health benefits of contact with nature. While Biophilic Design has gained traction in architecture and green infrastructure, its application to walkable street environments remains fragmented. We lack a coherent understanding of how nature-based interventions on streets influence physical and mental health, limiting the potential for integrated planning approaches that support both sustainable mobility and urban wellbeing.

What we did and why

We conducted a scoping review of 30 peer-reviewed English and Chinese articles to understand how Biophilic Design is used in walkable street environments. Our aim was to identify design typologies, uncover health-related mechanisms, and compare global knowledge systems. We wanted to fill the gap between evidence, design guidance, and policy, and support built environment practitioners and decision makers in applying more targeted, health-promoting strategies in urban street planning.

Our study’s contribution

his study offers the first comprehensive synthesis of Biophilic Design in walkable street contexts. We developed a framework linking four intervention types to five health-related mechanisms and wellbeing outcomes. Comparing English and Chinese-language research revealed contrasting emphases: English studies focus on ecological function and psychological restoration, while Chinese studies highlight cultural symbolism, social engagement, and place attachment. Our findings reframe streets as inclusive, restorative spaces for health—not just transport infrastructure.

Impacts for city policy and practice

This review provides a practical framework for integrating Biophilic Design into street-level planning to improve public health. City planners and policymakers can apply it to:
• Identify context-appropriate design strategies
• Align health, environment, and mobility goals
• Foster collaboration across planning, health, and sustainability sectors
By embedding nature into everyday infrastructure, our findings support evidence-informed decisions for healthier, more inclusive, and liveable streets and neighbourhoods.

Natural spaces and depression in urban older adults: Exploring types, accessibility, and mediators

Increasing the availability of urban green spaces, even small pocket green spaces, should be considered a promising intervention for reducing depression among older individuals. Beyond 100m, urban green space protection diminishes. WHO recommends that the population have a green space within a 300m radius. However, for older people, this threshold may be too distant.
However, not all green spaces confer mental health benefits; therefore, researchers and professionals should consider the differential effects of different categories of greenery.
