From Farm to Foundation: How Mushrooms Could Solve Kenya’s Housing Crisis – and Reshape Construction Globally
Kenya is facing a housing deficit of over 2 million units, a staggering number that’s forcing many into informal settlements and fueling a construction industry desperately seeking sustainable, affordable solutions. But the answer might not lie in newer, more efficient brick-making techniques – it could be growing right under our feet. A Nairobi-based company, MycoTile, is pioneering a revolutionary approach: building with mushrooms. Specifically, they’re harnessing the power of mycelium, the root structure of fungi, to create building materials that promise to be cheaper, more sustainable, and just as durable as traditional options.
The Rise of Mycelium Architecture: Beyond the Novelty
MycoTile isn’t the first to explore the potential of mycelium. Experiments with fungal building materials have been underway globally, from the NASA-technology-inspired mycelium house built in Namibia by MycoHAB in May 2024, to inventive mushroom coffins crafted in the Netherlands. However, MycoTile’s approach is particularly compelling due to its focus on scalability and addressing a critical local need. They combine mycelium with natural fibers and binding agents to produce panels suitable for insulation, interior design, and even structural components. Currently, they’re producing around 3,000 square meters of these materials monthly, a figure poised for significant growth.
A Cost-Effective Alternative in a Challenging Market
The economic benefits are immediately apparent. Street vendor Jedidah Murugi, who built a 15 square meter home using MycoTile’s panels for just 26,880 Kenyan shillings ($208), reports no discernible difference in quality compared to brick construction. “The only difference,” she says, “is in the cost.” Traditional construction in Nairobi can easily exceed $1,000 for a basic one-bedroom unit, potentially doubling with higher-quality finishes. MycoTile’s materials, however, can reduce building costs by as much as a third. This affordability is crucial in a country where homeownership is often a long, incremental process, and many are forced to live in unfinished homes to avoid rental costs.
Sustainability at the Core: A Circular Economy in Action
Beyond affordability, mycelium construction offers significant environmental advantages. As Nickson Otieno, a Nairobi-based architect and sustainability expert, points out, the construction industry is a major contributor to global emissions. MycoTile’s materials are biodegradable and have a low carbon footprint, aligning with Kenya’s new national plan for decarbonizing construction. But the sustainability story doesn’t end there. The company actively incorporates agricultural waste – specifically, waste from sugar factories in western Kenya – into their production process, consuming around 250 tons annually. This not only reduces waste but also creates a circular economy model, turning a potential pollutant into a valuable building resource.

From Research Kitchen to Industrial Scale
The journey of MycoTile founder Mtamu Kililo is a testament to the power of innovative thinking. Inspired by his research fellowship in Rwanda, where he observed the potential of mushroom farm substrates, Kililo began experimenting in his own kitchen. “I started doing a similar process, growing them in my pantry, baking them in my oven,” he recalls. What began as a research project has now blossomed into a commercially viable enterprise, supported by access to facilities at the Kenya Industrial Research and Development Institute.
The Future of Building: Mycelium and Beyond
MycoTile’s success isn’t just a Kenyan story; it’s a glimpse into the future of construction. As concerns about climate change and resource depletion intensify, the demand for sustainable building materials will only grow. We can expect to see further innovation in mycelium-based products, including stronger, more versatile materials and more efficient production processes. Furthermore, the integration of mycelium with other bio-based materials – such as hemp, flax, and agricultural residues – will likely unlock even greater potential. The key will be overcoming challenges related to scalability, standardization, and regulatory approval. However, the momentum is building, and the prospect of a future where our homes are literally grown, not built, is becoming increasingly realistic.
