How to Grow a House – Royal Institution Lecture June 2025

We talk about living buildings but what if a building could really be “alive”?

 

I attended a fascinating presentation of research at the Royal Institution, Professor Martyn Dade-Robertson revealed a future where buildings aren't just constructed—they're grown. Imagine foundations that heal themselves, walls that breathe, and roofs that respond to sunlight, all created by microscopic organisms working in harmony.

 

Robertson's research shows how bacteria can literally strengthen the ground beneath our feet. By introducing specially engineered microbes into soil, these tiny organisms can produce calcium carbonate crystals that bind soil particles together, creating foundations more resilient than traditional concrete methods.

 

Mycelium, the root network of mushrooms, is continually being celebrated as a revolutionary material for insulation, packaging, alternatives to plastics, but now, in experiments with NASA, Robertson's team have demonstrated how this fungal network could potentially create structures on Mars, growing insulation and structural components in resource-limited environments. A full-scale mycelium structure built in New York completely biodegraded within just four months of being dismantled.

 

The most fascinating aspect is the materials' ability to self-heal. Mycelium can "biologically weld" itself, fusing broken components back together. Bacterial cellulose can create surfaces that respond to light, changing colour like living skin—imagine walls that tan in sunlight or tiles that darken to provide shade.

 

These aren't just theoretical concepts. Robertson's team has already explored the waterproof nature of mushrooms. Hydrophobins are proteins which play a crucial role in mycelium's hydrophobicity (waterproofness!). They self-assemble at air-water interfaces, creating a hydrophobic layer on the surface of the mycelium. So the scientists have researched this hydrophobic behaviour and have tested coatings derived from bacterial proteins that can protect materials and make them fire-resistant. One experiment showed a piece of balsa wood treated with their protein coating survived a fire that would have quickly consumed an untreated piece.

Light that Nourishes

Light that Nourishes

To coincide with the publication of Issue 15 of The Light issue of the Journal of Biophilic Design, light aficionado Xander Cadisch writes.

We live bathed in an ocean of light, yet rarely consider how its invisible waves shape our very biology. Modern research reveals what ancient healers intuited—that light isn't just something we see, but a vital nutrient that regulates our cells, hormones, and nervous system. The implications for how we design our spaces are profound.

At the heart of this revelation lies a simple truth: different colours of light act as distinct biological signals. Take red light, for instance. With wavelengths between 630-700 nanometres, it penetrates deep into our tissues, stimulating mitochondria—those tiny power plants within our cells. This isn't speculative science, it's therapy approved by regulatory bodies like the FDA, now used to accelerate wound healing and ease arthritis pain. Hospitals are beginning to harness this knowledge, installing red light panels in recovery rooms where patients benefit from its regenerative properties.

The inaugural Biophilic Design Conference 2024

The inaugural Biophilic Design Conference 2024

London’s iconic Barbican conservatory couldn’t have been more fitting for a conference dedicated to the immense benefits of a world designed with biophilic principles. Visionaries, designers, architects, lawyers, academics, entrepreneurs, advocates and professionals across various walks in life, came together to share their perspectives for one full day in a series of talks. 

Noise at Work - how to improve results

Noise at Work - how to improve results

Croner-i published an article announcing the launch of the new UK Association formed to promote hearing conservation in the UK. The UK Hearing Conservation Association (HCA) claims that current noise risk at work management programmes are not working, and that improvements are needed in several key areas.

We are particularly interested in that their focus will be on preventable causes of hearing loss and hearing health impact “through common sense, cost effective, evidenced solutions”.
