Biophilic Interior Design: Why Nature Belongs at the Heart of the Home
I grew up in Finland, in homes where nature was never treated as something separate from everyday life.
Timber floors and furniture, generous windows with light curtains and views of trees were simply part of how a home looked and felt. At weekends, we spent time in a lakeside log cabin surrounded by woodland. The relationship between the house, the landscape and the people living there felt completely natural.
That is why I sometimes find it interesting when biophilic design is described as a new interiors trend. In the Nordic countries, a close relationship with nature has long shaped the way homes are designed: through light, natural materials, simplicity, warmth and an awareness of the seasons.
Today, when so much of life is spent indoors and in front of screens, that relationship feels more relevant than ever.
What is biophilic design?
The word biophilia describes our affinity with the living world. The idea was popularised by the biologist Edward O. Wilson, who proposed that human beings have an innate tendency to connect with life and natural processes.
In interiors, biophilic design is the intentional use of nature and nature-inspired elements to strengthen that connection. It is not a particular decorating style, and it is certainly not simply a matter of filling a room with houseplants.
It might mean making better use of daylight, framing a view of the garden, choosing timber, wool, linen or stone, introducing tactile surfaces, using colours drawn from the landscape, or arranging a room so that it offers both an open outlook and a comfortable sense of enclosure.
Biophilic design is often described through three broad ideas: direct experiences of nature, such as plants, daylight, fresh air and views; natural analogues, such as organic forms, materials and patterns; and spatial qualities that echo how we experience nature, including outlook, shelter, movement and discovery.
Why does it matter in a home?
A home does much more than provide a backdrop to daily life. It is where we recover from busy days, sleep, work, cook, gather with other people and spend a large part of our time. The sensory qualities of that environment, light, texture, sound, colour, views and materials, all influence how it feels to inhabit.
Research into nature and wellbeing has consistently found associations between contact with natural environments and benefits such as lower stress, improved mood and restored attention. Research specifically on biophilic interiors is still developing, and not every design feature has the same strength of evidence behind it, but the overall direction is compelling: people tend to respond positively to environments that provide meaningful contact with nature.
For residential interiors, this is useful because the interventions do not need to be dramatic. A chair positioned where you can see trees, morning light reaching the breakfast table, a tactile timber surface, natural textiles, or a glimpse of planting from a hallway can all contribute to the experience of a home.
The benefits of biophilic design.
One of the strongest reasons to think biophilically is the potential to create interiors that support restoration rather than add to sensory overload. Views of greenery, daylight and other natural cues have been associated with reduced stress and improved emotional wellbeing. Nature exposure has also been linked with better attention and cognitive restoration which is particularly relevant when our homes increasingly double as workplaces.
Daylight deserves particular attention. Exposure to natural light, especially earlier in the day, helps regulate our circadian rhythm. The internal body clock that influences alertness and sleep. In practical interior design terms, that can be as simple as considering where we sit in the morning, how heavily windows are dressed, and whether furniture blocks useful daylight.
There is also a sensory benefit. Natural materials are rarely perfectly uniform: timber has grain, stone has variation, linen creases, wool has texture and handmade objects carry subtle irregularities. These qualities bring visual and tactile richness to a room. They can make an interior feel more layered, authentic and connected to the natural world than a scheme made entirely from smooth, synthetic surfaces.
Importantly, biophilic design is not a medical treatment, and it should not be presented as one. Its value lies in shaping everyday environments in ways that are more supportive of human needs, creating opportunities for daylight, sensory variety, restoration and connection with nature.
Why wood feels so at home in biophilic interiors.
Wood is one of the materials most closely associated with biophilic design. Visually, it retains an obvious link to the tree it came from: grain, knots, tonal variation and texture make each piece slightly different.
There is emerging research suggesting that exposure to wood and other natural materials may have positive psychological or physiological effects, although the evidence is less extensive than the research on views of nature and access to green space. That is a useful distinction. We do not need to overstate the science to recognise that wood brings warmth, tactility and natural variation into an interior.
And it does not need to cover every surface. A timber floor, a piece of beautifully made furniture, oak joinery, a wooden lamp or a small section of panelling may be enough. Biophilic interiors tend to work best when natural elements feel integrated rather than applied as a theme.
Biophilia and Nordic design.
This is where biophilic thinking and Nordic design overlap so naturally.
In Finland and across the Nordic countries, interiors have long responded to climate, landscape and seasonal light. Daylight is precious during the darker months, so homes often make the most of windows, pale surfaces and uncluttered sight lines. Timber is familiar underfoot, in furniture and in everyday objects. Materials are valued not only for how they look when new, but for how they feel, wear and age.
The result is not necessarily minimal or neutral. Nordic interiors can be colourful, expressive and highly personal. What matters is the underlying relationship between function, material, light and nature.
At Studio Tiainen, that sensibility is central to my approach. Biophilic design is not about imposing a ‘natural’ look on a home. It is about creating interiors that feel connected to the people who live in them, to their surroundings and to the rhythms of everyday life.
How to bring biophilic design into your home.
You do not need a large renovation or a house full of plants to make a home more biophilic. Some of the most effective changes are surprisingly simple.
1. Start with daylight
Notice how light moves through your home during the day. Could a favourite chair, desk or breakfast table make better use of it? Sheer curtains, carefully placed mirrors and lighter surfaces can help daylight travel further without making a room feel stark.
2. Strengthen the view outside
A view does not have to be spectacular. A tree, a patch of sky, a courtyard or a few pots outside a window can provide a meaningful visual connection with nature. Arrange furniture so that these views become part of everyday life rather than something seen only when standing at the window.
3. Choose natural materials thoughtfully
Timber, wool, linen, stone, cork, clay and other natural materials introduce texture, variation and tactility. Choose them because they suit the room and will last — not simply because they carry a ‘natural’ label.
4. Use colour as a connection to landscape
Nature offers far more than green. Think of mineral blues, bark browns, ochres, clay reds, lichen, sand, chalk and the muted colours of changing seasons. A nature-inspired palette can be rich and expressive as well as soft.
5. Layer texture and sensory contrast
A smooth wooden surface beside woven wool, washed linen, handmade ceramic and soft upholstery creates a richer sensory experience than a room where every surface has the same finish. The aim is not visual busyness, but depth and variation.
6. Bring in living nature where it works
Plants can be wonderful, but they are only one tool. Choose species that suit the available light and the amount of care you genuinely want to give them. A few healthy plants are more effective than filling a room with greenery simply to achieve a look.
7. Create places for both outlook and retreat
We tend to enjoy spaces where we can see what is happening while still feeling comfortably contained. In a living room, that might mean an armchair with a view across the room and towards a window, but with a wall, bookcase or high-backed chair behind it. This idea of ‘prospect and refuge’ is one of the recognised patterns in biophilic design.
8. Let nature change with the seasons
Biophilic design becomes more meaningful when a home reflects the world outside. Branches, flowers, seasonal foliage, changing textiles or simply allowing the shifting quality of daylight to be noticed can create a stronger sense of time and place.
Biophilic does not automatically mean sustainable.
The two ideas often overlap, but they are not the same thing. A natural material is not automatically an environmentally responsible choice, and a room filled with new ‘eco-looking’ products is not necessarily sustainable.
For me, the better approach is to consider provenance, durability and longevity. Choose responsibly sourced timber, specify materials that are appropriate for their use, keep good-quality pieces in circulation, and design a home that will still feel relevant years from now. A lasting connection to nature should also encourage us to value the natural resources behind the things we bring into our homes.
A more human way to design.
The growing interest in biophilic design gives a name to something many of us recognise instinctively: being connected to nature can make us feel better.
That does not require turning a contemporary home into a greenhouse or making every room beige and woody. It can be subtle, sophisticated and deeply personal. It might be found in the quality of the daylight, the view from a favourite chair, the feel of linen against the skin, the grain of a table, a colour borrowed from the landscape or the way a room encourages you to pause and look outside.
For me, biophilic design is not a passing trend. It is a reminder that a beautiful interior should do more than look good. It should support the way we live and feel, while keeping us connected, in small, everyday ways, to the natural world beyond our walls.
Frequently Asked Questions
What is biophilic design in interior design?
Biophilic design is an approach that strengthens our connection with nature through the spaces we inhabit. In interiors, this can include daylight, plants, views, natural materials, tactile textures, nature-inspired colours and patterns, and layouts that create a sense of outlook, shelter and connection to the seasons.
Is biophilic design just about adding plants?
No. Plants are one expression of biophilic design, but the concept is much broader. A room can have a strong connection to nature through light, views, timber, stone, wool, linen, organic forms, natural colours and sensory variety even with very little planting.
What are the wellbeing benefits of biophilic design?
Research on contact with nature has linked it with lower stress, improved mood and restored attention. Studies of biophilic interiors are growing, although the strength of evidence varies between different design strategies. The most established principles include meaningful views of nature, access to daylight and other direct forms of nature connection.
How is biophilic design connected to Nordic interiors?
Nordic interiors have long placed importance on daylight, natural materials, craftsmanship, simplicity and a close relationship with the landscape. Those principles overlap strongly with biophilic design, even though they developed independently of the modern term.
Can biophilic design work in a modern home?
Absolutely. It works particularly well in contemporary interiors because natural materials, texture and planting can add warmth and sensory richness to clean lines and simple spaces without compromising a modern aesthetic.
Do I need a large budget to introduce biophilic design?
No. Repositioning furniture to make the most of a window, changing a heavy window treatment, introducing a natural textile, choosing a timber side table or adding a well-placed plant can all strengthen the connection with nature without major building work.
Is biophilic design sustainable?
It can support sustainable design, but the terms are not interchangeable. Sustainability depends on how materials are sourced, manufactured, transported, used and eventually reused or disposed of. Biophilic choices are strongest when they are also durable, responsibly sourced and appropriate for the home.
