Imagine stepping out of your spacecraft onto the dusty surface of Mars, your new home awaiting you. But this isn’t just any home – it’s a living, breathing structure grown from mushrooms. Sound like science fiction? Think again. Thanks to groundbreaking research by architects and scientists, this fungal future might be closer than you think.
The Mushroom Revolution in Space Architecture
As humanity sets its sights on establishing permanent settlements on the Moon and Mars, one of the biggest challenges we face is how to construct habitats in these harsh, alien environments. Traditional building materials are heavy and expensive to transport across the vast distances of space. That’s where an unlikely hero enters the scene: mushrooms, or more specifically, mycelium – the root-like structure of fungi.
American architecture firm Red House, in collaboration with NASA and the Massachusetts Institute of Technology (MIT) Center for Bits and Atoms, is pioneering a revolutionary approach to space habitats. They’re developing bio-habitats – homes made from living organisms – that could one day house astronauts and settlers on other worlds.
How Do You Grow a House on Mars?
The process of growing a Martian mushroom home is as fascinating as it sounds. Here’s how it might work:
- An uncrewed mission arrives on Mars carrying a compact, folded shelter inside a sealed bag.
- This bag contains a mixture of dehydrated algae (specifically chaetomorpha, or sea emerald) and dormant mycelium.
- A rover injects Martian carbon dioxide, nitrogen, and water into the sealed bag, rehydrating the algae.
- The algae produce oxygen, which nourishes the mycelium.
- The mycelium grows and expands, taking on its predetermined structural shape.
- Finally, the mycelium fuses with the algae, creating a rock-hard biomass stronger than concrete.
Christopher Maurer, founder and principal architect at Red House, describes the inflation process as “like blowing up a balloon.” What starts as a small, folded package could potentially transform into a full-sized habitat in a matter of weeks.
The Superpowers of Mycelium
You might be wondering why mushrooms are the chosen building material for these futuristic space homes. As it turns out, mycelium possesses some truly remarkable properties that make it ideal for extraterrestrial construction:
- Radiation Shield: One of the biggest threats to human life on Mars is high-energy radiation. Amazingly, mycelium has shown the ability to not only block this radiation but potentially convert it into a resource for creating more biomass.
- Strength: The fungus-bonded biomass is reportedly stronger than concrete, providing a durable structure in harsh alien environments.
- Compact Transportation: The dehydrated mycelium and algae mixture can be transported in a small, folded mass, dramatically reducing payload size for space missions.
- Self-Repairing: As a living material, mycelium has the potential to heal and repair itself, a valuable trait for structures in isolated space colonies.
From Earth to the Stars: Terrestrial Applications
While the prospect of mushroom homes on Mars is exciting, this technology isn’t just for space explorers. The principles behind these bio-habitats could revolutionize construction here on Earth, potentially addressing one of our planet’s most pressing issues: climate change.
The building industry is responsible for a staggering 40% of global carbon emissions. By shifting to mycelium-based construction, we could potentially reverse this trend. Instead of emitting carbon, buildings could actually store it, turning our cities into massive carbon sinks.
Moreover, the Red House team is exploring ways to use invasive species as a substrate for mycelium growth. In Namibia, they’re experimenting with the “encroacher bush,” an invasive plant that’s causing desertification. By using this harmful biomass in construction, we could tackle two environmental problems at once.

The Road to Mushroom Mars Homes
So, when can we expect to see the first mushroom dwelling on Mars? While the technology is promising, there’s still a long road ahead. Red House’s prototype has passed NASA’s proof of concept phase and is currently in the architectural design development stage. The next step would be a small-scale demonstration.
In the nearer term, the team is preparing to send a a small model of their design to the Moon using NASA’s Commercial Lunar Payload Service. This mission will test how the mycelium and algae behave in lunar conditions, providing valuable data for future developments.
The timeline for full-scale implementation depends largely on funding and technological advancements. With adequate support, we could see progress in years rather than decades. However, significant challenges remain, particularly in sourcing water on Mars to sustain these living structures.
A Fungal Future
As we stand on the threshold of becoming an interplanetary species, it’s clear that we need to think outside the box – or perhaps inside the mushroom – when it comes to space architecture. The concept of growing our homes from fungi may seem strange at first, but it represents a sustainable, adaptable, and potentially revolutionary approach to construction, both in space and on Earth.
Who knows? In the not-so-distant future, you might find yourself tending to your home as you would a garden, nurturing the very walls that protect you from the harsh Martian environment. As we continue to push the boundaries of space exploration, it’s clear that the solutions to our greatest challenges may come from the most unexpected places – even from beneath our feet.
