Biophilic Design

Bringing Nature Back to Our Built World

An innovative approach to architecture that integrates natural elements to create healthier, more sustainable spaces.

Reconnecting with Nature in Urban Environments

In an era where over half the global population lives in urban areas, many of us spend a staggering 80-90% of our lives indoors4 7 . This disconnect from the natural world has tangible costs, from increased stress and mental fatigue to reduced cognitive function.

Biophilic design integrates natural elements to create spaces that are not only more sustainable but also profoundly healthier for the people who use them5 7 .

The term "biophilia," meaning "love of life," was first coined by psychoanalyst Erich Fromm, who observed that our separation from nature through industrialization adversely impacts mental health4 . Harvard biologist E.O. Wilson later expanded this into the biophilia hypothesis, suggesting that humans possess an innate, biological affinity for nature and lifelike processes, forged over thousands of years of evolution.

Urban Reality

Over 50% of the world's population lives in urban areas, with many spending 80-90% of their time indoors.

Biophilic Solution

Integrating natural elements into built environments to improve health, well-being, and productivity.

The Science of Nature's Touch

The compelling rise of biophilic design is rooted in more than just a desire for aesthetically pleasing spaces; it is backed by rigorous scientific research demonstrating its positive impacts on human health and performance.

Stress Reduction Theory (SRT)

Proposed by Ulrich, this theory posits that exposure to natural environments facilitates stress recovery by reducing physiological arousal and negative emotions while fostering positive feelings3 .

Studies have shown that even brief nature exposure can lower blood pressure, reduce anxiety, and decrease stress-related cortisol hormones3 7 .

Attention Restoration Theory (ART)

Developed by Kaplan, ART suggests that natural environments are particularly effective at restoring our "directed attention"—the finite cognitive resource we use to concentrate on demanding tasks3 .

Nature engages our "involuntary attention" in a gentle, effortless way, allowing our directed attention to rest and replenish, leading to improved focus, memory, and cognitive performance7 .

Measurable Benefits Across Environments

A Framework for Design: From Theory to Pattern

To translate theory into practice, designers and researchers have developed robust frameworks that codify the elements of biophilic design.

Kellert's Six Elements of Biophilic Design

Environmental Features

Incorporating direct characteristics of the natural world, such as plants, water, sunlight, animals, and natural materials like wood and stone1 .

Natural Shapes and Forms

Using botanical and animal motifs, arches, vaults, and forms that resist straight lines and right angles1 .

Natural Patterns and Processes

Leveraging properties found in nature, such as sensory variability, balanced tension, and a "patina of time"1 .

Light and Space

Strategically using natural, filtered, and reflected light to create feelings of spaciousness and harmony1 .

Place-Based Relationships

Strengthening the connection to a location through its geography, history, ecology, and indigenous materials1 .

Evolved Human-Nature Relationships

Addressing fundamental human needs like prospect and refuge, curiosity, and a sense of mastery1 .

The 15 Patterns of Biophilic Design

This involves the direct, tangible presence of nature in a built environment. Examples include visual connections with nature (e.g., windows with views), dynamic light, airflow, presence of water, and botanical life9 .

Visual Connection Dynamic Light Airflow Water Presence Botanical Life

This category covers indirect experiences of nature through representations and simulations. It includes using natural materials (e.g., wood and stone), biomorphic forms (patterns that mimic contours in nature), and complexity and order (replicating the sensory richness of natural environments)9 .

Natural Materials Biomorphic Forms Complexity & Order

This refers to the spatial configurations found in nature that we find appealing. Key patterns include prospect and refuge, mystery (the promise of more information with a partially obscured view), and risk/peril (identifiable danger coupled with reliable protection)9 . The newly added pattern, Awe, describes the overwhelming experience of vast, majestic nature that forces us to mentally recalibrate our understanding of the world.

Experiment in Focus: Testing Biophilia in Virtual Reality

As biophilic design gains traction, researchers are using advanced technology like Virtual Reality (VR) to conduct controlled experiments. A 2025 study published in Scientific Reports investigated whether the benefits of biophilic design extend to spatial interaction tasks, specifically a path steering task in a virtual environment3 .

Non-Biophilic Office

Without any plants

Results and Analysis: A Surprising Outcome

Contrary to the researchers' initial hypothesis, the presence of virtual plants did not significantly affect steering performance3 . Participants completed the tasks in a similar amount of time in both the biophilic and non-biophilic offices.

This experiment highlights a crucial nuance: the effects of biophilic design can be task-specific. While it may not enhance every type of performance (like a well-practiced motor task), its primary and well-documented benefits lie in reducing stress and restoring cognitive capacity.

Biophilic Design in Action: From Airport to Classroom

The true power of biophilic design is revealed in its real-world applications, where it transforms everyday spaces into restorative environments.

Recomposure at the Airport

The redesigned Portland International Airport (PDX) is a masterclass in applied biophilia. The design team strategically used biophilic patterns to target passenger stress points.

After the security checkpoint, where travelers often feel flustered, canopy trees in the seating area provide a sense of prospect and refuge—offering protection overhead while allowing a clear view ahead.

Instead of sterile metal benches, passengers repack their bags while sitting on boulder-shaped planters under trees, a deliberate design to aid recomposure.

Classroom with natural light
Inspiration in Education

A 2025 public survey study exposed participants to images of educational spaces with varying levels of biophilic quality.

The results strongly supported the positive effect of biophilic design on psychological states, including a novel benefit: stimulating inspiration4 .

This finding suggests that biophilic classrooms can do more than just reduce stress; they can actively enhance creativity and learning.

"Biophilic design in educational settings not only reduces stress but actively stimulates inspiration and enhances the learning experience."

The Future of Biophilic Design

Biophilic design is more than a trend; it is an essential shift in how we conceive of our built environment. It acknowledges that our physical surroundings are not just backdrops to our lives but active participants in our health, well-being, and performance.

As research continues to evolve, incorporating new patterns like Awe and documenting benefits like inspiration4 , the case for integrating nature into every building we design and occupy becomes ever more compelling.

The goal is clear: to create buildings and cities that don't just shelter us, but that help us thrive, by reconnecting us to the natural world we instinctively love.

The Path Forward

The future of architecture lies in creating spaces that not only minimize environmental impact but actively contribute to human health and well-being through intentional connections with nature.
