Biophilic design rests on a simple idea: human beings have an inborn need to connect with nature, and the spaces we live in either support the need or suppress it.
The term biophilia, which means the love of living things, was made popular by the biologist E.O. Wilson in the 1980s, and the research that has developed around it makes a great case for designing interiors that incorporate natural elements, patterns, and sensory experiences, rather than excluding them in favour of ‘manufactured’ environments.
The research backs this up clearly. Studies in hospitals, offices, and homes all show that spaces with natural light, greenery, and natural materials help people feel less stressed, focus better, recover from illness more quickly, and feel more comfortable overall. For interior designers, this is not just an interesting fact; it is a reason to design differently.
The Three Pillars of Biophilic Design
Biophilic design is broken down into three areas. Each one gives you a different set of tools for bringing nature into an interior space.
1. Nature in the Space
This is the most direct approach, bringing living or natural elements indoors. The elements include:
- Green walls (moss)
- Indoor trees
- Water features
- Natural light
- Fresh air
It also means engaging in the senses:
- Sound of moving/flowing water.
- The smell of natural materials.
- The feel of rough stone or warm timber underfoot.
2. Natural Analogues
This covers materials, shapes, and patterns that remind us of nature without being nature itself:
- Timber cladding
- Stone flooring
- Linen fabrics
- Leaf-pattern wallcoverings
- Furniture with curved organic shapes
So do fractal patterns like the irregular, repeating shapes found in leaves, branches, and coastlines, which our brains find naturally easier (and more restful) to process than perfectly regular or purely random patterns.
3. Nature of the Indoor Space
This is about how an indoor space feels to move through and live in. It draws on the kinds of environments we all feel safe and comfortable in. This includes the combination of open views with sheltered corners; think of a window seat tucked into an alcove, as well as a sense of curiosity, where it feels like there’s more to reveal around the next corner. Even some sense of drama like a glass floor panel or an exposed structural beam can contribute to a space that feels alive and engaging.
Applying Biophilic Principles in Practice
Knowing the theory of biophilic design helps, but the real skill is turning it into actual design decisions.
Natural light should be the first thing you consider on any project. The way light moves through a space during the day, its direction, intensity, and warmth, affects how people feel, how well they sleep, and how large or comfortable a room seems.
Where architecture limits natural light, lighting systems that gradually shift in warmth and brightness can replicate some of those natural effects.
Material choices are another area where biophilic thinking makes a practical difference. Timber, stone, clay, wool, linen, and leather all bring qualities that synthetic materials cannot match. The grain of wood, the veining in marble, the slight irregularity of a woven textile. That natural variation is part of what makes these materials feel warm and interesting rather than flat and clinical.
Planting is often the most noticeable change a designer can make indoors. But choosing the right scale and placement matters just as much as the plants chosen. One large, well-positioned specimen plant makes a different impact than a collection of small pots scattered around a room.
Planting built into joinery or placed at eye level feels like a considered design decision rather than a mere decorative add-on.
Biophilic Design Audit Tool
Whether you are an interior designer, decorator, or homeowner, you can use the interactive checklist below to assess how well a current or proposed interior addresses the core principles of biophilic design.
It is designed for use at the design review stage of a project and covers the three pillars above across residential and commercial contexts.
*The audit tool below lets you score an indoor space across the three pillars of biophilic design: nature in interior spaces, natural analogues, and the nature of the space, so that you can identify where the strongest opportunities for improvement lie.*

A Note on Authenticity
Biophilic design works best when it is woven into the design concept from the beginning and not at the end. A planted wall in a space that is otherwise poorly lit, artificially finished, and acoustically uncomfortable deals with one issue while leaving everything else unchanged. It ends up looking decorative rather than feeling genuinely restorative.
The most successful biophilic interiors work across several layers at once: light, materials, form, sound, and spatial quality all reinforcing the same idea. The result is a space that feels, without the occupant necessarily being able to explain why, like somewhere they belong.
For designers who want to build expertise in sustainable and wellness-focused practice, biophilic design connects both disciplines directly, and the demand for it is growing across every sector of the profession.
