Made in Brunel: A structure grown from mushrooms

A Brunel University London student has been exploring how mushrooms can be used to grow robust zero-waste structures as an alternative to conventional building techniques – while also providing a tasty noodle topping!

In collaboration with environmentally-focused architecture firm Astudio, Aleksi Vesaluoma’s Grown Structures use mycelium (oyster mushroom spawn) mixed with cardboard. The material is then moulded into ‘mushroom sausages’ by packing the mixture into a tubular cotton bandage.

The mushroom sausages are shaped over a mould of the preferred shape and grown over four weeks in a ventilated greenhouse, resulting in a striking structure with potential use at festivals or other events, which could be easily biodegraded afterwards.

The large quantities of gourmet mushrooms which pop out from the structure can also be picked and eaten, creating a novel architectural surrounding that doubles as a food source. A restaurant grown from mushrooms, serving mushroom meals, is just one potential idea for the project’s future, say the creators.

While a number of designers, artists and companies are also working with mycelium in a range of different ways, Aleksi’s artistic and versatile new ‘sausage’ technique is new to the field and a launch-pad for further developments – enhancing the structure’s strength, reshaping into different designs, or building on a smaller scale, for example.

Aleksi explains:

“Right now the main factors holding back the mass-commercialisation of mycelium materials are people’s pre-assumptions, as well as the power of the profit-driven materials industry.

“Mycelium materials are beneficial to us and the environment as well as just being… really cool. They’re another great example of why we need to trust the intelligence of nature in helping us create more regenerative systems of manufacture.”

When mycelium grows throughout organic materials such as straw, it binds the matter together like glue. The resulting materials are extremely versatile and when used in construction, have the potential to ease environmental problems caused by resource depletion, deforestation for wood or toxic emissions from brick firing.

Aleksi adds:

“Exploring the structural potentials of mycelium materials could help in shaping a future where architecture is grown from bottom up rather than consuming resources and creating waste.

“Various solutions are being commercialised in the USA and Netherlands but in my opinion the material needs to be introduced to a much wider market, including the UK.”

Aleksi has recently formed the design collective MANDIN; friends, artists and designers brought together by a shared vision for experimentation, nature and non-conventional thinking.
