Active Design Guidelines: Promoting Physical Activity and Health in Design: Summary & Key Insights

Every guideline in this book rests upon a foundation of scientific research linking the built environment to health behaviors. The evidence is clear and growing: our physical surroundings influence how much we move, how often we interact, and even how we feel about our neighborhoods. Epidemiological studies have repeatedly found that residents of walkable communities exhibit lower rates of obesity and cardiovascular disease, while those in auto-dependent environments are more likely to be sedentary.

In public health, we often talk about ‘dose-response’ relationships. The built environment has its own: the more accessible and appealing the active options—stairs, sidewalks, bike lanes—the more likely people are to use them. Studies conducted in New York City, for instance, demonstrated that usage of stairs increased dramatically when design improvements such as better lighting and visible signage were introduced. Across neighborhoods, the presence of mixed land use, proximity to public transit, and pedestrian infrastructure correlate with higher daily physical activity.

For us, the evidence also has a social dimension. Designing for activity does more than raise heart rates; it rebuilds a sense of shared public life. Children walking to school, adults encountering each other on shaded sidewalks, elders resting in well-designed plazas—all contribute to safer, more vibrant, and connected communities. When we design for active living, we design for comfort, equity, and opportunity.

Our approach begins with a set of foundational principles that guide every subsequent recommendation: accessibility, connectivity, and inclusivity. Accessibility ensures that spaces invite participation for all ages and abilities. Connectivity links destinations through intuitive pathways and networks that make walking or cycling the natural choice. Inclusivity reminds us that health-promoting design cannot be the privilege of a few neighborhoods; it must extend to every corner of the city.

An active design is both physical and psychological. It must appeal to the senses—light-filled corridors, attractive stairs, visible sightlines between indoor and outdoor spaces—and it must remove barriers, both literal and perceptual. For instance, placing stairs prominently near building entrances subtly normalizes their use, whereas hidden, enclosed stairwells discourage it. Streets designed for slow traffic speeds and ample sidewalks change behavior because they signal safety and comfort.

These principles do not constitute an aesthetic style; they are a public ethic. They remind us that every square foot of design either contributes to human flourishing or detracts from it.
