How NASA's Mycelium Construction Tech Could Redefine Housing on Earth and the Moon

NASA's mycelium-based construction technology could transform housing on Earth and the Moon by turning fast-growing fungi into strong, carbon-negative bricks and self-assembling habitats. This breakthrough links food production and building material in a single biological process, slashing costs, emissions, and launch mass for future space missions while opening a new path to affordable, sustainable housing on our own planet. Read on to see how lab experiments became real homes in Namibia—and why the same process may one day build lunar bases.

NASA Turns Fungi into Building Blocks—and the Idea Is Already Building Houses

Researchers at NASA’s Ames Research Center, working with architecture studio redhouse, discovered that the root-like mycelia of Ganoderma lucidum mushrooms can bind agricultural waste into a rigid, lightweight composite. Originally funded under the NASA Innovative Advanced Concepts (NIAC) program to explore off-planet habitats, the work proved that the same mycelium can produce both edible mushrooms and a structural matrix once dried and heat-treated.

That insight spun off into Mycohab, a Namibian venture that grows gourmet mushrooms for local markets and then bakes the spent substrate into one-cubic-foot “mycoblocks.” Using abundant, invasive Acacia mellifera as feedstock, Mycohab built a demonstration house in 2024 for about $8,000—showing that a technology devised for the Moon can solve urgent housing and environmental problems on Earth.

Why Mushroom Bricks Matter: Carbon, Cost, and Off-Planet Logistics

Conventional concrete emits roughly one kilogram of CO₂ per kilogram produced; mycelium bricks sequester an equal amount of CO₂, flipping the carbon equation. Because the process uses local biowaste instead of quarried rock or fired clay, it also cuts water use, energy demand, and heavy-material transport costs—critical benefits in regions with limited infrastructure.

For spaceflight, mass is money. Shipping finished walls to the Moon is prohibitive, but launching a lightweight scaffold, dehydrated nutrients, and starter spores is feasible. Once hydrated, the fungi grow to fill inflatable molds, harden into shape, and create radiation-dampening, thermally insulating shells—all before astronauts even arrive. The dual-use biology means early crews get fresh food and finished shelters from the same payload.

From Namibian Villages to Lunar Settlements—What Comes Next

Mycohab plans to license its growth recipes so builders worldwide can turn local straw, husks, or brush into low-cost housing, disaster-relief shelters, or acoustic panels. NASA, meanwhile, is testing mycelium samples for fire resistance, toxicity, and micro-gravity growth on the forthcoming Starlab station.

Future iterations could blend lunar regolith or Martian dust into the substrate, further boosting strength and shielding. With automated bioreactors and 3D-printed scaffolds, entire habitat modules might one day be ‘grown’ in situ, closing life-support loops by recycling organic waste into both calories and walls.
