  • Why we need nature inside our buildings - The Future of Healthy Buildings with Biophilic Design

    Why we need nature inside our buildings - The Future of Healthy Buildings with Biophilic Design
    May 18 2026
    In this episode of the Journal of Biophilic Design podcast, we speak with landscape specialist Tom Palfreyman, whose work across commercial, hospitality, retail and workplace environments has focused on the principle that plants fundamentally change how people experience space. With more than twenty years’ involvement in interior and exterior landscaping, Tom has spent his career exploring how nature can improve the places where we work, rest and play, and why maintenance, care and long-term thinking are just as important as the initial design itself. As Tom reflects during the conversation, “Plants have transitioned from a nice-to-have decoration in the corner of the building to being an intrinsic essential part of any building.” It is a shift many designers are now recognising. The conversation around biophilic design has matured significantly over the past decade. What was once dismissed as aesthetic enhancement is increasingly understood as part of a much wider discussion around health, wellbeing, productivity, ecology and human resilience. The heart of biophilic design beats out that human beings are not separate from nature, we are an intrinsic part of it. “We evolved to live outside,” Tom says. “That connection with nature, sadly, I believe, has been lost.” Modern life has created increasingly artificial environments - sealed buildings, screen-based working, urban density and spaces designed more for efficiency than human experience. Yet our biology has not changed at the same pace as our architecture. Research across neuroscience, environmental psychology and workplace wellbeing continues to show that exposure to nature can reduce stress, restore attention, support cognitive performance and improve emotional wellbeing. What becomes clear in this discussion is that successful biophilic design is never simply about adding greenery into a room. It is about creating meaningful and lasting relationships between people and living systems. For Tom, this begins with understanding plants properly. “Putting the right plant in the right place so it’s happy, healthy, survives,” he explains. There is something important in that statement. Too often, planting schemes are treated as visual afterthoughts rather than living ecosystems requiring expertise, maintenance and long-term stewardship.The strongest biophilic projects understand that planting design is not decoration. It is infrastructure for wellbeing. Tom highlights his collaboration with Dr. Craig Knight, emphasising the benefits of biophilic ‘enrichment’, a word maybe more commonly associated with ecology or animal wellbeing than commercial interiors. “Enrichment is a very, very strong part of what we do, putting the right plants in the right place,” he says. “If we can have engaged enrichment, then that is far more powerful.” Tom shares an example of a project with a pharmaceutical company where biophilic enrichment was introduced, leading to significant improvements in the work environment and prompting the company to adopt a global biophilic strategy. This notion of engaged enrichment feels particularly relevant in workplaces today. Many office environments continue to struggle with issues of stress, disengagement and sensory fatigue. In contrast, spaces designed with visible natural systems, daylight, planting and moments of restoration often feel fundamentally different. They soften the intensity of modern working life and reintroduce cues of life, seasonality and care into daily experience. Even relatively small interventions can have measurable impact. “Just one plant per four square meters can make a difference,” Tom notes, pointing to research that demonstrates improvements in wellbeing and engagement through relatively modest levels of planting integration. Importantly, the placement of greenery matters as much as quantity. Tom speaks about focusing on “main areas of circulation, so entrance and exit points of the buildings, communal spaces, places where people are going to perhaps take a moment to recuperate.” These transitional spaces are psychologically significant. They shape first impressions, influence behaviour and provide opportunities for pause and recovery within otherwise fast-paced environments. Biophilic design, at its best, works subtly in the background. A staircase wrapped in planting encourages movement differently. A naturally lit communal area changes how people gather. A view towards greenery can lower stress responses almost instantaneously. These are not superficial gestures; they alter the emotional atmosphere of buildings. Tom shares the inspiring work that Square Mile Farms are doing, introducing edibles into the working environment, focusing on education, engagement, and community building. They create gardening clubs where people can harvest plants like basil, replant, and take home produce to make recipes like pesto. This initiative rekindles lost skills...

  • Is Colour the Missing Link in Nature-Centric Biophilic Spaces

    Is Colour the Missing Link in Nature-Centric Biophilic Spaces
    Apr 24 2026
    Ever wondered why some spaces instantly relax you, while others energise or even irritate? The secret might lie in the colour! Karen Haller, is an expert in applied colour psychology, and reveals how understanding the emotional dance of colours can transform our built environments into havens of well-being and productivity. Whether you're an interior designer, architect, or simply a lover of nature-inspired spaces, this podcast dives deep into the unseen forces of colour. You’ll learn how colour influences behaviour, how to select the perfect hues for different environments, and why true biophilic design demands more than green and brown, it's about the symphony of natural colours that heal and energise us. Colour Psychology seems to be a bit of a missing link in biophilic Design. Not a lot of people are talking about it but it is vitally important. We’ve all seen it—spaces drenched in beige, sterile white corridors, or overly vibrant hues that overpower instead of soothe. Spaces, especially healthcare environments, often neglect the impact colour can have on users of the space. Karen shatters the myth of “neutral” colours being emotionally neutral altogether. Every colour triggers a response, whether it is positive or negative, each is embedded in our personal memories, cultural beliefs, and innate responses. For example, red energises or stimulates physical reactions, but excess can overwhelm. Blue can be calming or stimulating, depending on its shade and context. Recognising this nuanced language of colours allows designers to craft environments that truly support human health and behaviour. Whether it's selecting hues for a hospital or designing a peaceful workspace, understanding the emotional implications of colour creates spaces that nurture rather than numb. 3 ways we relate to Colour – and how to use them! Karen’s theory identifies three distinct ways we connect with colour:Personal Associations:Colours evoke memories and feelings unique to each individual. A bright yellow might remind someone of their childhood joy or a dull green might trigger childhood discomfort. These associations drive our preferences and aversions—so understanding clients’ personal ties to colours is key.Cultural Meanings:Deep-rooted beliefs shape cultural responses—red for luck in China, white as a symbol of death elsewhere. Ignoring these can cause disconnect in design choices for diverse spaces.Colour Psychology:Each hue has a spectrum of responses aligned with nature’s endless diversity.Recognising these layers allows designers to create intentionally harmonious spaces—be it a calming hospital room or an energetic collaborative zone. Nature's palette can guide authentic Biophilic DesignNature’s colours can be perceived almost like a blueprint for emotional well-being. Karen emphasises the importance of sticking to true natural colours, no artificial greens or overly saturated hues. These colours, like the rust reds of autumn leaves or the soft lavender of seasonal blooms, carry intrinsic harmony and emotional resonance. When designing with nature in mind, identify the desired outcome, calm, energy, focus and select natural hues that support these goals. For a high-energy space like a bustling office, vibrant reds or energizing oranges may work. In contrast, serene blues and gentle greens foster calm in healthcare or relaxation zones. But please avoid the cliché of “green and brown”, these are just two colours among many. True biophilic design encompasses the entire spectrum of natural colours, creating an ecosystem of shades that balance, connect, and heal. Good biophilic design comes complete with a understanding of emotional language of colours. Genuine biophilic design is rooted in understanding this language, aligning space with human innate responses, and collaborating across disciplines. Whether it’s a hospital, office, or school, the goal is harmony, balancing energy levels, fostering comfort, encouraging productivity. This is achieved by starting from the outcomes and working backwards, what behaviours must be supported? What emotions should be evoked? Then, select colours accordingly. Remember, every space is an ecosystem, and our role is to nurture human-nature connection through thoughtful colour choices, never just following trends but listening to what nature and our psychology say. When you understand the true language of colour, you wield a tool you can use to shape environments that heal, energise, and sustain us. Dive deeper with Karen Haller’s courses or consult her for tailored strategies. Start viewing spaces as living ecosystems filled with the colours of nature, inspired by human psychology, and crafted for well-being. Because colour can also help restore our innate connection to the natural world.

  • The Future of Material Innovation and Biophilic Design

    The Future of Material Innovation and Biophilic Design
    Apr 14 2026
    Have you ever wondered how materials shape our environment? What happens when design meets nature? If you’re craving a fresh perspective on sustainable, regenerative design, dive deep with us into the world of materials, creativity, and a future where biophilic principles transform every building, every product, and every space. William Knight, co-founder of Material Matters, is a passionate advocate for a future where materials tell stories, innovate endlessly, and reconnect us to nature. His journey from politics to design might surprise you, but his journey has driven him to demystify material innovation that truly inspires. In this post, you’ll discover how materials are pushing boundaries, why understanding them is critical, and how a shift in industry mindset can accelerate regenerative, biophilic environments. Living Materials and Regenerative Design Will emphasises that many materials we overlook have rich stories. Think about timber, agricultural waste, natural extracts, all of these can inspire radically different design solutions. For example, his work with companies using tree sap, algae-based bioplastics, or recycled aluminium demonstrates that every material is an opportunity. This perspective challenges the traditional sourcing black book, pushing designers to explore alternatives that are biophilic, regenerative, and resourceful. Yes, natural waste and renewable sources are eco-friendly but they can also create compelling products that challenge our assumptions and expand design possibilities. Will’s own story began unconventionally, with his early career in the House of Commons. From navigating politics to working with the UK Design Council, his journey reflects a passion for shaping perceptions and pushing creative boundaries. His work has spanned exhibitions, festivals, and major design events, with a focus on how materials are the foundation of design innovation. Today, Material Matters is a platform for exploring the pulse of material intelligence. Its an accessible, open conversation about process, resourcefulness, and ecological mindfulness. It’s about bringing transparency and democratising knowledge so everyone, from designers to end consumers, can make smarter, sustainable choices. Designing for a Biophilic Future One of the most exciting areas Will touches on is the role of biophilic design principles, the integration of natural elements into environments to foster wellbeing and sustainability. He reminds us that design is inherently reactive, it responds to market demand, manufacturing capabilities, and cultural shifts. But the real game-changer? Materials that mimic or derive directly from nature, like bio-based concrete infused with moss, or fungi-based textiles, enable us to create living buildings and products. William highlights an inspiring example: materials with embedded bio-growth, which grow, adapt, and even repair themselves. They embody nature’s resilience and regenerative capacity, leading us toward healthier, more adaptable spaces. Designers can act as catalysts, demonstrating and advocating for natural, sustainable materials. Success hinges on collaborating across sectors. Supply chains, manufacturing, regulation—each influences whether innovations reach the mainstream. We need inclusive platforms and storytelling, engaging property developers, clients, and end users in the process. When supply chains embrace natural waste, local resources, and regenerative practices, scale becomes feasible, collaborative, cross-sector thinking is key. Regenerative and biophilic materials must be supported by resilient supply chains and more succinct regulation, a collective effort fuelled by shared knowledge and a willingness to challenge orthodoxies. Your challenge: Think beyond the usual. Dive into local resources, embrace natural waste, and collaborate across disciplines to create environments that resonate deeply with human nature. The future of architecture and design is rooted in materials that are alive, local, and regenerative.
