Biophilic Interior Design and Natural Materials for a Healthier Home
Have you ever walked through a forest, listened to the sound of rain, or looked out at the sea and instantly felt calmer and more refreshed? It is not simply an emotional reaction.
Human beings have lived in close connection with the natural world for thousands of years. Even today, our brains continue to respond positively to natural light, greenery, organic materials and harmonious landscapes.
Today, however, we spend most of our time indoors, often surrounded by artificial surfaces, static lighting and increasingly fast-paced lifestyles. This growing disconnection from nature can affect our mental and physical balance, our ability to focus and our overall sense of wellbeing at home.
Biophilic interior design was created to restore this connection. It is not simply about adding a few plants to a room, but about designing spaces inspired by nature through light, natural materials, organic shapes, colours and spatial flow.
In this complete guide, the experts at TopArredi will walk you through the principles of contemporary biophilic design, showing you how to transform your home into a calmer, more balanced and deeply restorative living space.
The Biophilia Hypothesis: Why the Human Brain Seeks Nature
The term Biophilia (literally meaning love of life) was introduced by biologist Edward O. Wilson to describe the innate human tendency to seek connection with nature and living organisms.
Studies in environmental psychology and neuroarchitecture have shown that the brain responds positively to natural stimuli. Sunlight, vegetation, water, organic materials and soft natural forms can trigger neurophysiological responses associated with calmness, safety and mental restoration.
This response is often linked to:
- reduced stress perception
- improved emotional comfort
- better focus and concentration
- a stronger sense of balance and wellbeing
- reduced cognitive fatigue
To apply these principles to interior design, the international research firm Terrapin Bright Green developed the well-known “14 Patterns of Biophilic Design”, now considered one of the leading frameworks for wellbeing-focused interior architecture.
Biophilic principles can be divided into three main areas:
- direct connection with nature
- natural references through materials and forms
- spatial configuration and environmental flow
The Three Dimensions of Biophilic Design at Home
A truly biophilic home is not created by a single decorative feature, but by balancing light, materials, space and sensory perception.
1. Nature in the Space: Bringing Natural Elements Indoors
This dimension includes everything that physically introduces nature into the home: natural daylight, ventilation, greenery, water and living organic elements.
Indoor plants, for example, improve the perception of freshness within a room and help create a more relaxing and welcoming atmosphere.
Several studies, including the famous NASA research conducted in controlled environments, have also analysed the ability of certain plant species to absorb volatile organic compounds present in indoor air.
The presence of greenery works closely together with natural lighting design, a topic explored further in our guide on home lighting and wellbeing.
2. Natural Analogues: Organic Materials, Textures and Shapes
The human brain recognises nature even when it is referenced indirectly.
This happens through:
- solid wood furniture
- natural stone
- marble surfaces
- textured fabrics such as linen and wool
- soft curved forms
- organic and irregular textures
Fractal patterns — commonly found in leaves, wood grain and ocean waves — are processed naturally by the visual system, helping reduce sensory fatigue and visual stress.
The TopArredi material philosophy: true biophilic interiors should also engage the sense of touch. The authentic texture of wood, stone and natural fabrics creates a feeling of warmth, comfort and stability that fully synthetic materials rarely achieve.
The Biophilic Design Framework
| Biophilic Pattern | Core Principle | Perceived Benefit | TopArredi Application |
|---|---|---|---|
| Visual connection with greenery | Natural light and indoor vegetation | Emotional comfort and reduced stress perception | Green walls, shelving with integrated planters and preserved greenery |
| Organic materials | Authentic textures and natural surfaces | Greater sense of warmth and comfort | Solid wood tables, ribbed finishes, stone tops and natural fabrics |
| Biomorphic forms | Curved lines inspired by nature | Visual harmony and spatial fluidity | Curved sofas, organic coffee tables and soft-edged mirrors |
| Prospect and refuge | Protected spaces with open outward views | A stronger feeling of safety and relaxation | Wraparound armchairs and relaxation areas positioned near natural light |
Chapter 1: Earth-Inspired Colour Palettes and Biophilic Tones
Biophilic interior design uses colour palettes directly inspired by nature.
The most effective tones generally include:
- sage green
- olive green
- terracotta
- warm beige
- stone grey
- natural browns
These shades create a sense of stability, balance and visual continuity. The brain perceives them as familiar and comforting, reducing the sensory overload often caused by overly cold or artificial interiors.
Biophilic palettes also help create interiors that feel softer, calmer and more harmonious in everyday life.

Chapter 2: Prospect and Refuge in Interior Layout Design
The human brain instinctively seeks two spatial conditions:
- an open and unobstructed view of the surrounding environment
- a protected and reassuring space that feels safe and comfortable
These principles are known as Prospect and Refuge and represent one of the foundations of contemporary neuroarchitecture.
In residential interiors, they can be recreated through:
- fluid and breathable layouts
- low-profile furniture that keeps the room visually open
- protected reading corners
- wraparound seating
- relaxation areas positioned near natural daylight
This type of layout helps create an immediate feeling of comfort, calmness and emotional security within the home.
The relationship between space, perception and wellbeing is explored further in our guide on neuroarchitecture and wellbeing at home.
Chapter 3: Visual Order, Nature and Mental Wellbeing
A biophilic home does not mean filling every room with natural elements without balance.
Even greenery, when used excessively or without visual harmony, can create sensory overload and visual clutter.
That is why biophilic design only works effectively when combined with:
- visual order
- harmonious layouts
- clutter-free spaces
- balanced volumes
- well-designed storage solutions
Removing unnecessary clutter allows natural materials, textures and daylight to become the true focal points of the interior.

Biophilic Interior Design FAQ
What is biophilic interior design?
Biophilic interior design is a design approach that integrates natural elements into living spaces to improve comfort, wellbeing and the overall quality of the home environment.
Do you need lots of plants to create a biophilic home?
No. Biophilic design also includes natural light, authentic materials, nature-inspired colour palettes, organic textures and more harmonious spatial layouts.
Which plants are considered best for improving indoor air quality according to NASA?
The famous NASA Clean Air Study showed that some plants can act as natural biological filters, helping remove airborne toxins such as formaldehyde, benzene and xylene. Among the most effective and resilient choices for interior spaces are Sansevieria (Snake Plant), Peace Lily, Pothos, Aglaonema and Parlour Palm. Adding these plants to living areas or home offices combines visual appeal with meaningful indoor air quality benefits.
Which materials work best in a biophilic interior?
Solid wood, natural stone, linen, wool, raw cotton and textured finishes are among the most commonly used materials for contemporary biophilic interiors.
Do curved shapes really improve visual comfort?
Yes. Soft, organic lines are generally perceived by the brain as more harmonious and relaxing compared to overly rigid or aggressive geometries.
How can I apply biophilic design in a small apartment?
Even small spaces can embrace biophilic principles through: natural light, earthy colour palettes, authentic materials, softly shaped furniture and more fluid, organised layouts.
