Every summer, the Museum of Modern Art introduces a new design to its outdoor pavilion. This year a group of Brooklyn architects will build a series of sinuous towers made with bricks grown from mycelium, the thread-like underground section of fungus. “Mycotecture” has been previously used to make ultra-sustainable packaging and insulation. The towers will not only filter the summer heat, they will also be organic, sustainable, and best of all, compostable. With all that going for it, the pavilion will no doubt be welcomed as a champignon exhibit.
