Biophilic design is an approach to architecture and interior design that connects people with nature in the buildings where they live and work, through daylight, fresh air, plants, water, natural materials, views and spaces that feel like natural settings. It grew from biophilia, the human affinity for living things that the biologist Edward O. Wilson popularized in 1984, and was shaped by the social ecologist Stephen Kellert and by Terrapin Bright Green's report 14 Patterns of Biophilic Design (2014).
This guide explains Kellert's principles and the 14 patterns, shows five built examples with their architects and dates, summarizes what the research shows, compares biophilic design with green design, biomimicry and organic architecture, and gives practical steps for homes, offices and healthcare. The last sections cover what AI can do for biophilic design today, and what it cannot.
What Is Biophilic Design?
The word biophilia was first used by the psychoanalyst Erich Fromm, who described it as the "passionate love of life and of all that is alive" (Wikipedia). The biologist Edward O. Wilson turned it into a hypothesis in his book Biophilia (1984), defining it as "the innate tendency [in human beings] to focus on life and lifelike process" (Harvard University Press).
Biophilic design applies that idea to buildings. Stephen Kellert (1943–2016), the social ecologist who developed it, explained why it matters: today's "natural habitat" is largely the built environment, where we now spend "90% of our time" (Metropolis, 2015). The aim is to bring the kinds of contact with nature that people evolved with, such as light, air, water, plants, views and shelter, back into homes, offices, schools, hospitals and cities. Applied to whole buildings it is often called biophilic architecture; inside a home or an office, biophilic interior design.
Biophilic Design Principles: Kellert's Framework
In his 2015 essay What Is and Is Not Biophilic Design?, Kellert set out five conditions that separate biophilic design from simply adding greenery:
Human adaptations to the natural world: it focuses on the contact with nature that has helped human health, fitness and wellbeing over evolutionary time.
Repeated and sustained engagement: an occasional or isolated experience of nature has only superficial and fleeting effects.
Reinforcing and integrating interventions: nature has to connect with the whole space; in Kellert's words, "an isolated plant or an out of context picture" is not effective biophilic design.
Emotional attachment to places: good biophilic design makes people attached to the places they use, and more likely to care for them.
Positive interactions between people and nature: it fosters connections between people, their environment and their community.
He then grouped the practice into three kinds of experience, described in detail in the book The Practice of Biophilic Design by Kellert and Calabrese (biophilic-design.com, 2015):
Kellert's experience | What it includes | In a building, for example |
|---|---|---|
Direct experience of nature | Light, air, water, plants, animals, weather, natural landscapes and ecosystems | Windows that open, a courtyard garden, a pond or fountain, a view of the sky |
Indirect experience of nature | Images of nature, natural materials, natural colors, simulated natural light and air, naturalistic shapes and forms, evoking nature, information richness, age, change and the patina of time, natural geometries, biomimicry, mobility and wayfinding, cultural and ecological attachment to place | Timber and stone, leaf-like patterns, earth tones, local materials, a clear route through the building |
Experience of space and place | Prospect and refuge, organized complexity, integration of parts to wholes, transitional spaces | A window seat with a long view, a sheltered reading nook, a porch or veranda between inside and outside |
Many design guides, such as Neumann Monson's, also cite six elements or principles attributed to Kellert's earlier work: environmental features; natural shapes and forms; natural patterns and processes; light and space; place-based relationships; and evolved human–nature relationships.
The 14 Patterns of Biophilic Design
In 2014 the firm Terrapin Bright Green published 14 Patterns of Biophilic Design by William Browning, Catherine Ryan and Joseph Clancy, drawn from over 500 publications on how people respond to nature. It sorts the patterns into three categories: Nature in the Space, the direct presence of plants, water, animals, breezes, sounds and scents; Natural Analogues, non-living and indirect evocations of nature such as materials, colors, shapes and patterns; and Nature of the Space, the spatial configurations found in nature. The table sums up Terrapin's definition of each pattern, with design moves taken from its examples.
Pattern | Category | What it means | Design moves |
|---|---|---|---|
1. Visual Connection with Nature | Nature in the Space | A view to elements of nature, living systems and natural processes | Windows onto trees or water, a green wall, a courtyard garden |
2. Non-Visual Connection with Nature | Nature in the Space | Sounds, textures, scents or tastes that refer to nature | Operable windows, fragrant herbs and flowers, textured wood and stone, flowing water |
3. Non-Rhythmic Sensory Stimuli | Nature in the Space | Brief, unpredictable natural movement or sound | Leaves moving in a breeze, dappled light, reflections of water on a surface |
4. Thermal & Airflow Variability | Nature in the Space | Subtle changes in air temperature, humidity and airflow, as outdoors | Cross ventilation, sun and shade, windows that open |
5. Presence of Water | Nature in the Space | Seeing, hearing or touching water | A fountain, a water wall, an aquarium, a pond |
6. Dynamic & Diffuse Light | Nature in the Space | Light and shadow that change over time | Daylight from several angles, low-glare lighting, white light by day and less blue light at night |
7. Connection with Natural Systems | Nature in the Space | Awareness of natural processes, especially the seasons | Visible rainwater, seasonal planting, wildlife habitats, materials that weather |
8. Biomorphic Forms & Patterns | Natural Analogues | Symbolic references to contoured, patterned, textured or numerical arrangements found in nature | Leaf- or shell-like forms, organic curves in the structure or the furniture |
9. Material Connection with Nature | Natural Analogues | Natural materials with minimal processing that reflect the local ecology or geology | Local timber, stone and clay; leather, copper or wood left to gain a patina |
10. Complexity & Order | Natural Analogues | Rich sensory information in a spatial hierarchy like nature's | Fractal patterns of mid-range complexity: Terrapin suggests "broadly speaking, D=1.3-1.75" and warns that overuse "could instill discomfort" |
11. Prospect | Nature of the Space | An unimpeded view over a distance | A raised seat by a window, a balcony over a garden |
12. Refuge | Nature of the Space | A place to withdraw, protected from behind and overhead | A reading nook, a lowered ceiling or a canopy over a seat |
13. Mystery | Nature of the Space | Partially obscured views that draw people further in | Winding paths, curving walls, a garden glimpsed through a screen |
14. Risk/Peril | Nature of the Space | An identifiable threat with a reliable safeguard | A cantilevered balcony, a glass floor, a catwalk over an atrium |
Biophilic Architecture Examples
Five built projects show the patterns at different scales, from a residential tower to a corporate campus. Each project name links to the architect's or the owner's own page, read in October 2026.
Project | City | Year | What makes it biophilic |
|---|---|---|---|
Bosco Verticale (Boeri Studio) | Milan | 2007–2014 | Two residential towers, 110 m and 76 m tall, planted with 800 trees, 4,500 shrubs and 20,000 plants from about a hundred species |
One Central Park (Ateliers Jean Nouvel) | Sydney | 2008–2014 | A vertical landscape by the botanist Patrick Blanc covers about 50% of the façade; a motorized heliostat reflects sunlight into the park the tower shades |
Jewel Changi Airport (Safdie Architects) | Singapore | 2019 | The Rain Vortex, which Safdie calls the world's tallest indoor waterfall, a terraced Forest Valley and a Canopy Park with 14,000 m² of attractions among the gardens |
The Spheres (Amazon) | Seattle | 2018 | A workplace with more than 40,000 plants from the cloud-forest regions of over 30 countries |
Apple Park (Foster + Partners with Apple) | Cupertino | 2017 | A 175-acre campus with over 9,000 native and drought-resistant trees, an orchard, a meadow and a pond; Apple calls its main building the world's largest naturally ventilated building |
Benefits of Biophilic Design: What the Research Shows
Terrapin's report sums up the evidence: biophilic design "can reduce stress, enhance creativity and clarity of thought, improve our well-being and expedite healing". Four sources show where the figures come from:
Faster recovery in hospital: in a study published in Science in 1984, Roger Ulrich compared surgery patients in a Pennsylvania hospital. The 23 whose windows looked onto a natural scene had shorter postoperative stays, fewer negative comments in nurses' notes and took fewer strong painkillers than 23 matched patients whose windows faced a brick wall (doi.org).
Time in nature: a study of 19,806 people in England (Scientific Reports, 2019) found that at least 120 minutes a week in nature was associated with good health and well-being, with no further gain beyond 200 to 300 minutes (Nature). It measured visits to nature, not buildings, but it supports regular access to gardens, parks and green views.
Offices: Terrapin's The Economics of Biophilia estimates that views to nature in an office "can save over $2,000 per employee per year" in office costs. It is Terrapin's estimate, not a result measured in a particular building.
Cooler roofs and streets: the US EPA reports that the surface of a green roof can be 56 °F (about 31 °C) cooler than a conventional roof and nearby air up to 20 °F (about 11 °C) cooler, and that green roofs can reduce a building's cooling load by 70 percent and provide habitat (EPA).
Biophilic Design vs Green Design, Biomimicry and Organic Architecture
The four terms overlap and projects often combine them, but each answers a different question:
Approach | Main question | Typical features |
|---|---|---|
Biophilic design | How do people experience nature in this space? | Daylight, views, plants, water, natural materials, prospect and refuge |
Green (sustainable) design | How does the building reduce its impact on the environment? | Energy and water efficiency, low-carbon materials, renewable energy |
Biomimicry | How does nature solve this technical problem? | Forms, structures or systems modeled on natural processes; Kellert lists it as one attribute of the indirect experience of nature |
Organic architecture | How does the building grow from its site, materials and purpose? | Frank Lloyd Wright's idea of a building in harmony with its setting |
A building can be green without being biophilic, such as an efficient sealed box with no views, and biophilic without being especially green, such as a lobby with a large fountain that uses a lot of water and energy. The best projects aim for both. For Frank Lloyd Wright's approach and famous examples such as Fallingwater, see our guide to organic architecture.
How to Apply Biophilic Design
Start with what costs least and has the strongest evidence, daylight, views and fresh air, then add plants, water and natural materials, and finally shape the space itself. Terrapin's economics report points out that measures such as access to plants, natural views and daylight can have "very low or no up-front cost".
Daylight, Views and Fresh Air
Give the rooms people use most daylight from more than one direction and a view of trees, sky or water, and put seats and desks where people can see out (Visual Connection with Nature, Dynamic & Diffuse Light). Windows that open bring airflow and outdoor sounds, and a mix of sunny and shaded spots lets people choose where they feel comfortable. On a floor plan these are decisions about where the windows go, how big they are, how high the sill is and which way each room faces, and they are cheapest to change before anything is built. For more on light, see our guide to lighting design.
Plan daylight and views on your floor plan Draw the walls and rooms by hand or over a picture of your plan, place each window with its width, height and sill, and check the sun direction in the 3D view. Add wood, stone or tile finishes, then walk through the rooms in first person, free in a desktop browser. |
Plants and Water
Living plants and water are the most direct way to bring nature in. Following Kellert's integration condition, group plants where people spend time and connect them with light and views rather than spreading single pots around the room, and choose species that suit the light, the climate and the care they will get; native plants also support local wildlife. Water can be a small fountain, a water wall, an aquarium or a pond, but Terrapin notes that water features "can be water and energy intensive", so use them sparingly in dry climates.
Natural Materials and Colors
Wood, stone, clay, wool and linen with little processing, ideally from the region, give what Terrapin calls a Material Connection with Nature, and materials that gain a patina, such as leather, copper or wood, show the passage of time. For color, biophilic schemes usually rely on earth tones, the subdued browns, greens and blues found in nature, and use brighter colors sparingly, as Wikipedia's article on biophilic design summarizes. Our posts on sustainable materials and color psychology go deeper.
Prospect, Refuge and Complexity
Natural settings offer both long views and sheltered places, and good interiors do the same: a raised seat or a balcony with a view over a distance (prospect), a reading nook or a low canopy that protects from behind and overhead (refuge), and a curving path or a partly hidden garden that invites people further (mystery). Rich but ordered detail, such as a leaf pattern or a timber ceiling, adds complexity without clutter. These are layout decisions, so sketch them early: a free floor plan creator lets you place the window seat, the nook and the route through the house with wall lengths and room areas. Our guide to spatial design covers how spaces follow one another.
Biophilic Interior Design at Home
At home, start with the room you use most: move the main seat or desk toward the window, keep sills and views clear, group several plants that suit the light, add natural materials you touch every day, such as a wooden table, a wool rug or linen curtains, and make one sheltered corner for reading or rest. If you rent, plants, textiles, a rug and a new furniture layout already cover several patterns.
To see a greener version of your own room before you buy anything, upload a photo of it to ArchiVinci's Interior module, select Plants under Add object, choose the Daylight lighting option and describe the materials in a sentence, for example "oak floor, linen sofa, stone side table, large leafy plants by the window". ArchiVinci generates a new image that follows your photo, in seconds; there is no style picker, so your words set the style.
Made in the Interior module with Plants under Add object, the Daylight button and the prompt "Biophilic living room: many large leafy plants, oak floor, linen sofa, stone side table, daylight from big windows".

Offices and Healthcare
In offices, the low-cost measures matter most: desks near windows with a view, plants in the spaces people use, quiet refuge spaces for focused work and natural materials. The International Living Future Institute features Seattle's Bullitt Center among its biophilic design case studies as "the first commercial office building to be fully certified as a Living Building" (ILFI). In hospitals, Ulrich's window study is the classic argument for views of nature from patient rooms, and gardens, daylight and natural materials in waiting areas follow the same logic. To see an office or a clinic concept as an image first, see ArchiVinci's pages on AI office design and AI hospital design.
Facades, Gardens and Green Roofs
Outside, biophilic design means green facades, planted balconies and terraces, green roofs and gardens that people can see from inside and use. Bosco Verticale and One Central Park show the scale of a tower; at the scale of a house, a garden with native planting, a sheltered seat and a view from the main rooms does the same work. Our posts on facade renovation and landscape architecture cover both in more detail.
To try a garden around an existing house, AI landscape rendering in ArchiVinci starts from a photo or a view of the house and a sentence describing the garden. In the example below, the upload is a generated picture of a house on a bare plot; the prompt asked for a lawn, a stone path, ornamental grasses, low shrubs and a few young trees, and the result came out in evening light.
Left: the uploaded image. Right: the result of the prompt "Landscaped garden with a lawn, a stone path to the entrance, ornamental grasses, low shrubs and a few young trees." on the default engine.
How AI Is Shaping Biophilic Design Today
AI helps biophilic design mainly on the visual side: image generators show a room, a facade or a garden with more plants, daylight or timber, which makes it easier to compare directions and explain them to a client. Checking whether a design really gets enough daylight, sun and fresh air is a different job, done by simulation software that is mostly not AI. It helps to keep the two apart.
Seeing Biophilic Options Before You Build
Architects and designers can upload a photo, a sketch or a 3D model view of a project and describe the biophilic version in a sentence: more plants, a green roof, timber, stone and daylight. With AI rendering in ArchiVinci, every run generates a new image that follows the upload, in seconds, so several versions of the same room or facade can be compared side by side with a client; with a plan, one run gives up to four images.
For a facade, a photo or a model view of the building and a prompt such as "climbing plants on the facade, planted balconies and a green roof" give a planted version of the same building with AI exterior design. Each result is a picture: it shows what the space could look like, not how much daylight, airflow or energy it will get. The default engine is asked to keep the perspective and geometry of the upload, but details can change, so check them before presenting. Using the images for client work or marketing needs an active plan.
Analysis: Daylight, Energy and Airflow Simulation
To find out how much daylight a room gets, how the sun moves across a facade or how air flows through a plan, designers use simulation. Ladybug Tools, for example, is free and open source, runs inside 3D modeling software and connects validated engines such as Radiance, EnergyPlus/OpenStudio, Therm/Window and OpenFOAM for daylight, energy, thermal and airflow studies. These are simulation engines, not AI, and their results depend on the model and the inputs.
Some buildings also use sensors and automated controls to adjust lighting, shading and ventilation as conditions change. When such systems collect data about the people inside, occupants should know what is collected and how it is used.
What Research Says About AI and Biophilic Design
Research on AI in biophilic design is still young. A study by Thampanichwat and colleagues in the journal Buildings (February 2025) showed architects 30 images made with DALL-E 3, Midjourney and Stable Diffusion and analyzed how they then described biophilic design in 10 categories: their language became more detailed and clear, but in some cases it was constrained by the images (doi.org). The practical lesson: AI images help put a biophilic idea into words and pictures, while the designer checks that it suits the place and the people.
Challenges and Criticism of Biophilic Design
Biophilic design has limits and critics, and a good project plans for them:
Cost and maintenance: green walls and water features can be expensive to install and to maintain, which limits them in cost-sensitive projects, and they need expertise in ecology and landscape design, as the criticism collected on Wikipedia notes. Daylight, views, windows that open and potted plants cost far less.
Greenwashing: a few plants or a picture of nature added to an otherwise unchanged building give the look of environmental care without its substance; Kellert's integration condition is the test.
Biodiversity: critics argue that many projects add greenery for people's enjoyment without creating habitat or helping local ecosystems; native plants help both people and wildlife.
Privacy: buildings whose controls rely on sensors collect data about their occupants, which calls for transparency and consent.
Biophilic Cities
At city scale, biophilic design means nature in everyday urban life: street trees, parks within walking distance, green roofs and walls, and access to water. The Biophilic Cities network connects partner cities around the world, which report their progress each year. In Singapore, Moshe Safdie describes his Jewel Changi Airport as echoing the city's reputation as "The City in the Garden".
Conclusion: Harmony Between Nature and Technology
Biophilic design is less about adding plants than about how people experience a building: daylight and views first, then plants, water and natural materials, then spaces with prospect, refuge and a little mystery. Kellert's principles and Terrapin's 14 patterns give the checklist, the examples show it at every scale, and the research on views, daylight and time in nature explains why it matters. AI image tools make it faster to see and share a biophilic version of a room, a facade or a garden; questions of daylight, energy and airflow still belong to simulation and to the people who design and look after the building.

Frequently Asked Questions
What is the main goal of biophilic architecture?
To give people regular, meaningful contact with nature inside the buildings where they spend most of their time: daylight, fresh air, views, plants, water, natural materials and spaces that feel like natural settings. Kellert described it as creating "good habitat for people as biological organisms" in modern buildings, landscapes and communities.
What are the three pillars of biophilic design?
The phrase is used for two closely related groupings. Terrapin Bright Green sorts its 14 patterns into three categories: Nature in the Space, Natural Analogues and Nature of the Space. Kellert grouped the practice into three experiences: direct experience of nature, indirect experience of nature, and experience of space and place. Both say the same thing: bring real nature in, evoke it through materials and forms, and shape spaces the way natural settings are shaped.
What are the 14 patterns of biophilic design?
They are Terrapin Bright Green's 14 patterns of 2014: Visual Connection with Nature, Non-Visual Connection with Nature, Non-Rhythmic Sensory Stimuli, Thermal & Airflow Variability, Presence of Water, Dynamic & Diffuse Light, Connection with Natural Systems, Biomorphic Forms & Patterns, Material Connection with Nature, Complexity & Order, Prospect, Refuge, Mystery and Risk/Peril. The table above explains each one with design examples.
Who coined the term biophilia?
The psychoanalyst Erich Fromm first used the word biophilia. The biologist Edward O. Wilson made it widely known with his book Biophilia (1984) and the biophilia hypothesis, and the social ecologist Stephen Kellert developed biophilic design from it.
What are biophilic colors?
Earth tones: the subdued browns, greens and blues of soil, stone, leaves, water and sky. Biophilic schemes use them on large surfaces and keep bright colors for small accents, while natural materials such as wood and stone bring their own color and texture.
Is biophilic design greenwashing?
It can be, when it means a few plants or a picture of nature added to an otherwise unchanged building. Kellert's own principles rule this out: nature has to be integrated with the whole space and experienced again and again. Real biophilic design changes how a space works, its daylight, views, air, materials and layout, and its greenery is cared for over time.
What are the disadvantages of biophilic design?
Green walls, planted facades and water features can be expensive to install and maintain, use water and energy and need specialist knowledge, and greenery added only for show does little for people or wildlife. The cheapest measures, such as daylight, views, windows that open and well-chosen plants, avoid most of these drawbacks, and Terrapin notes that they can have very low or no up-front cost.
Can AI help with biophilic design?
Yes, mainly for visualizing options. In ArchiVinci you upload a photo, a sketch or a 3D model view and describe the biophilic version, for example more plants, daylight and timber; the Interior module also has a Plants button and a Daylight option, and every run generates a new image that follows your upload, in seconds. A new account starts with 3 free credits. AI images do not calculate daylight, energy or airflow: for that, designers use simulation tools such as Ladybug Tools.
