Humans copying nature
Our own attempts to copy nature’s structure-building capacity has left us with products that are far inferior to nature’s originals—pleather (plastic leather) versus leather, particleboard versus wood and synthetic textiles, to name a few. Without nature’s capacity for micro-assembly, we loose the best properties of natural materials are.

Enter mycelium.
Mycelium is kind of like yeast (both are fungi), but unlike most yeast cells, which grow as a single cell, mycelium is multi-cellular and grows into macro-size structures—which we most often recognize as mushrooms. Not only does mycelium produce small molecules, but it gently and with supreme precision assembles them into complex structures so small that they are invisible to the human eye.

Mycelium workings
Working much like single-celled yeast, mycelium takes in small molecules of food—typically sugar but often from sources such as wood or plant waste—by excreting enzymes that break these materials down into digestible morsels. As the mycelium grows it assembles a dense network of long, microscopic fibers that grow through the substrate like a superhighway system.

Once the mycelium has fully built its network, it moves on to its next stage: building a mushroom. This is where humans can intervene. Rather than letting a mushroom pop up out of the substrate, the mycelium builds predictable structures by controlling temperature, CO2, humidity and airflow to influence the growth of tissue. *This is a rapid process: the accumulation of fibers becomes a visible speck after a few hours, a visible sheet after a day or two, and an 18-by-2-by-12-inch (45.72-by-5.08-by-30.48-centimeter) sheet weighing a couple of pounds (~1 Kilogram) within the course of a week.

When mushrooms go into the lab: growing design

Ms. Tonevitskaya- Mycelium in Construction>Mycotecture? A New Era Bio-Building

In Ms. Tonevitskaya’s post linked above, she includes some very helpful illustrations that visualize her feeling that: “The possibilities are endless. Mycelium based materials could be very hard, soft, porous, weightless, could look like leather, plastic or paper, could have any texture, patterns and colors, could demonstrate high-temperature performance, corrosion resistance or conductivity, covering the requirements of a number of potential applications in architecture, design and fashion”.

I have noticed that some viewers are asking questions like: *How long does it take to see it growing?
What are the properties of mycelium of use in Construction? Where are mycelium bricks?

Maybe I have found you some answers………..

Mycelium troubleshooting- Mycelium in Construction>Mycotecture? A New Era Bio-Building

Grow Mushrooms: Learning How to Troubleshoot
Although many factors may influence your success, there are some common mistakes that are easily avoided. I’ve listed eight big ones below, along with practical solutions. If you’re just learning to grow mushrooms, review this list to save yourself both time and heartache. Even if you’re a veteran, it never hurts to come back to the basics.

Mushroom Cultivation: 5 Common Mistakes to Avoid
Here are some mistakes that we made when we first started to grow mushrooms. Sometimes it’s good to learn from your own mistakes, other times it’s enough to learn from others.

Mycelium in Construction >insulation made from mycelium

Growing and testing mycelium bricks as building insulation materials

2018 Abstract. In order to improve energy performance of buildings, insulation materials are being used in increasing quantities, which may lead to potential depletions of raw materials. One sustainable solution suggested is the use of bio-based, biodegradable materials. In this paper, we examine a novel type of bio insulation materials – mycelium. The aim is to produce mycelium materials that may have insulation properties and to have properties that match existing building insulation in terms of physical and mechanical characteristics but with an enhanced level of biodegradability. The testing data showed mycelium bricks exhibited good thermal performance. We plan future work to improve growing process and thermal performance of the mycelium bricks.

Is Mushroom Insulation the World’s
Greenest Insulating Material?

Mycelium insulation Construction- Mycelium in Construction>Mycotecture? A New Era Bio-Building
Ecovative Insulation sandwich wall system used on the Mushroom Tiny House.

July 2013, Rather than blowing agents, this insulation uses growing agents. It’s natural, made with agricultural waste and fungi. You grow it in place. It has No hydrocarbons, and it yields little to no toxic waste. Compared to most other insulation materials, it takes little energy to make the stuff

A past project of Ecovative Design is their:
Mushroom Tiny House
that exhibits their insulation product’s properties.


January 2019 – Critical Concrete – After the good results from our mycelium experimentations (mentioned in this link) during the Summer School 2018 we decided to explore further the promising results from the cardboard bricks to improve our production process. This new step in our research was lead by the objectives of reducing the economical costs and the time of the production for a future bigger scale production. 

Water: Our last experiment tested waterproof properties: as we discovered, flowing water on the surface is not a factor of damage for the material. Above we observe the drops not penetrating the surface.

Mycelium in Construction >Mycelium Bricks & properties of mycelium for construction

weather-proof   >>  correct me if I am wrong, but it seems that weather/water proof is the biggest draw back at this point, to Mycelium Bricks.   water-resistance  

In my first post on Construction with Mycelium, I noted the following: 

  • Weather-proofing them without destroying their essential “compostability” has been a concern.  Natural oil has been used to penetrate into the bricks. They have been tested in a “home shower” and found to only gain a few percentage points of mass. “They don’t go really soggy and flexible,” says the fabricator from Ecovative.

INSIGHTS INTO MYCELIUM – an interview with Maurizio Montalti

Maruizio Montalti- Mycelium in Construction>Mycotecture? A New Era Bio-Building

14/05/2018 From the interview:
Is there a way to make the material weather-proof from the outside environment without destroying its compostability? Would natural oil penetration be a partial solution, like in the Hy-Fi tower by David Benjamin? Or  shellac, a solution applied by Phil Ross?
The finishing is one of the most important things in order for something that looks like a material to actually become a product. There are different kinds of oils that have been traditionally and effectively used for wood treatment in the inside or outside environment. For example, linseed oil is commonly used for the conservation of old wooden furniture. However, it is really not a permanent solution, as it requiries maintenance and reapplied every once in a while. Waxes are an equally interesting solution but as in the case of oils, applied over and over again. Shellac on the other hand, is a great natural polymer but also a quite expensive material compared to other industrial solutions, particularly when thinking about scale and high production volumes. Moreover shellac, as well as linseed oil, changes the quality of the material as it creates a film on top that seals its pores. Therefore, if the point is to have a porous material that allows the wall to breath, shellac is not the correct option. These are all temporary solutions applicable for projects that are not meant to be in place for a long time.
For this reason, we are currently working with nanoparticles that penetrates the pores and still keep the structure open. Nowadays we are trying to develop our own formulations in order to create coating systems that could maintain the feel, the look and the qualities of the original material, while enhancing its durability. For instance, one compound that I am currently testing is nanocellulose, which is completely natural and promises to be a great future coating system even though not yet developed as such.

Lots of people are researching, testing, working on the “Mycelium Brick” potential:

Advanced Materials From Fungal Mycelium: Fabrication and Tuning of Physical Properties
2017 Abstract: We present in this work a new category of self-growing, fibrous, natural composite materials with controlled physical properties that produce in large quantities and over wide areas, based on mycelium, the main body of fungi. … One result: The materials grown on cellulose contained more chitin and showed higher Young’s modulus and lower elongation than those grown on dextrose-containing substrates, indicating that the mycelium materials get stiffer when their feeding substrate is harder to digest. The possibility of tailoring mycelium materials’ properties by properly choosing their nutrient substrates paves the way for their use in various scale applications.

Effect of Temperature and Growth Media on Mycelium Growth of Pleurotus Ostreatus and Ganoderma Lucidum Strains
July 2019 The aims of the study are to identify an effective and versatile fungal strain for bioengineering mycelium composites. We investigated the influence of temperature and four different growth media on mycelium growth of two white rot fungi, Pleurotus ostreatus (Winter Oyster) and Ganoderma lucidum (Reishi) in laboratory conditions.
P. ostreatus produced best mycelium morphologies on potato dextrose agar supplemented with yeast extract (PDYA) followed by potato dextrose agar (PDA) and sabouraud dextrose agar (SDA). This showed mycelium morphology of P. ostreatus is significantly improved with supplemented carbon and nitrogen sources grown at optimal temperature of 22 °C.

Fabrication factors influencing mechanical, moisture- and water-related properties of mycelium-based composites November 2018
>The fungus type influences homogeneity of mycelium composite materials – thickness of the fungal skin.
>The fungal skin impacts mechanical behaviour of the composite material and improves water resistance.
>Straw-based materials are stiffer and less moisture-resistant than cotton-based mycelium composites.
>Heat pressing improves homogeneity, strength and stiffness of mycelium composite material.
>Heat-pressed mycelium materials have similar density and elastic modulus as natural materials (e.g. cork and wood).

November 2018 mycelium with glass: Architecture graduate student Tayana Ghosh has developed a new building material that combines mycelium fungus with glass. Ms. Ghosh’s research shows potential that the mycelium-glass material is a potential insulation for boards or sandwich panels, instead of foams. As next steps, she recommends additional testing of the material, including its fire resistance and shear strength.

CLAYCELIUM_ LIVING STRUCTURES – no longer any links to this

Claycelium (Clay+Mycelium) is a project developed at IAAC, Institute for Advanced Architecture of Catalonia, in collaboration with IIT, Italian Institute of Technology. Justin Sheinberg and Mert Gonul Justin Sheinberg and Mert Gonul created Claycelium during the 2018/19 MAA01, Digital Matter program.”

Claycelium for furniture, walls, columns and more.

A very comprehensive report:
From the conclusion in our 5 phases of experiments and the requirements we set for ourselves,  we began to develop claycelium with Coffee grounds and sawdust acting as the nutrients and the clay and mycelium acting as structure. These nutrients we collected locally at no cost.

After choosing our composite for Claycelium, we then began to investigate its use in Robotic Construction. We used 3 versions of paste deposition modeling extruders in our research.

From these tests we were able to conclude that Claycelium is 19% stronger in tensile strength than clay. These results were compared against a variety of tests and each test was performed multiple times.

2019 FAIRE: The North of France’s mining area is a famous territory for its productive history that also reveals an innovative past. An important plasturgic production had its place during the coal epic. This project emerges from this tradition between industry and innovation.

Sarah, Rym and Dania are three fifth year students from the Architecture and Landscape school of Lille. They are working since several months on renewable materials as part of miner dwellings’ restoration in the city of Rouvroy.

Launched in 2017 by the Pavillon de l’Arsenal and the City of Paris, with the support of Caisse des Dépôts and in collaboration with MINI, the FAIRE platform invites multi-targeted teams, architects, urban planners, landscape architects, engineers, designers, to propose innovative research and experimental projects to meet major urban challenges: climate, materials crisis, new technologies, solidarity, cleanliness, mobility….

Growing Pavilion – before and during DDW 2019. Dutch Design Week , 19-27 October, 2019

The world of architecture, construction and design cannot and must not stay behind. In fact, with The Growing Pavilion we show the possibilities and above all the enormous beauty of biobased materials.
The Growing Pavilion shows how far we can go at this moment in the ambition to build completely biobased, and the new aesthetic that comes with it. Because our ambitions extend beyond the possibilities, it leads to new and unexpected encounters that grow together towards a total biobased future. We want to appeal to construction professionals, architecture, and design as well as a wide audience to look at the power, importance and beauty of biobased building. Are you ready for this next step?

Living architecture: World-first ‘smart’ fungal building

fungal construction- Mycelium in Construction>Mycotecture? A New Era Bio-Building

September 2019 A group of international researchers are set out to develop an intelligent building grown from mycelium and capable of adaptively reacting to changes in light, temperature and pollution. The project is funded by EU  a third of which is allocated to CITA, Centre of Information Technology and Architecture at KADK. 

Fungal Architectures is the second EU Future and Emerging Technologies funded project for CITA that focuses on integrating living complexes in novel architectural technologies. The academic partners in the project are UWE Bristol in the UK (coordinating partner) and Utrecht University in Holland. The industry partner is MOGU, a mycelium-based technologies company based in Italy.

September 2019, For the second year, The Institute for Advanced Architecture of Catalonia (IAAC) and Swinburne School of Design continue to share their passion for architectural experimentation and sharing of ideas in the second IAAC Global Summer School workshop at Swinburne. Architecture students are being introduced to new digital structural optimisation workflow tools using proprietary apps and software programs such as Ameba, to visualise and test the performance of structural forms in 3D.
The large laser-cut form is the scaffold for mycelium cultivation. The substrate, mixed with mycelium culture, was placed inside the mould and transferred into an incubator in the biology lab over the two-week workshop period….Looking for more sustainable production methods, students investigated CNC machining of mycelium and the possibility of cutting a form from a preformed block of mycelium grown in a standard reusable incubating bag.

The European Space Agency is exploring whether fungi can grow buildings, like labs and other facilities, in space. Nasa (below) is also examining whether their Mars missions could grow surface structures on the planet itself. NASA is considering the production on Earth of a flexible plastic shell seeded with mycelium and then activating the fungal growth once on Mars.

Myco-architecture off planet: growing surface structures at destination

NASA Mycelium Construction- Mycelium in Construction>Mycotecture? A New Era Bio-Building

The trade-off
A turtle carries its own habitat. While it is reliable, the trade-off is that it costs energy. NASA makes the same trade-off when it transports habitats and other structures needed to lunar and planetary surfaces, increasing upmass, and affecting other mission goals.

Housing in Outer-Space
Imagine a self-assembling habitat made of a light, fibrous material, with excellent mechanical properties. The material could be used dry, wet, frozen with water or as part of a self-produced composite which could allow such enhancements as radiation protection and a vapor seal. It is self-replicating so the habitat could be extended at a future date, and self-repairing. Some form of this material could be used for a habitat at destination, additional buildings, the shell of multiple rovers and furniture.

Mycelium – the solution?
The fibrous material is fungal mycelium, the vegetative structure of fungi consisting of branching, thread-like hyphae. Mycelial materials, already commercially produced, are insulators, fire retardant, and do not produce toxic gasses. These materiels can have compression strengths superior to dimensional lumber, flexural strength superior to reinforced concrete, and competitive insulation values. As mycelia normally excrete enzymes, it should be possible to bioengineer them to secrete other materials on demand such as bioplastics or latex to form a biocomposite. ……
