Hygeroscope is a meteor sensitive morphology, which is designed by Achim Menges in collaboration with SteffenReichert. It is an installation that is with a glass case, which simulates the external humidity changes of Paris, France at the Pompidue building.

It’s a virtual simulation of the exterior climate that is in a controlled setting. Once the humidity changes from about 35% to 80%, which is a normal humidity change that you could experience from a clear day to a rainy day, then the structure material is programmed so when the humidity in the wood cells of the structure when absorbed would expand.

The expansion would trigger with the composite material that they developed which results in a shape change. When the humidity levels are high the structure opens and once the humidity level drops the structure will shut again. They used algorithms to generate the form of the structure, which allowed them to fabricate each piece of the structure as well.

This system is collected of custom made mechanism from a combination of quarter cut maple veneers and synthetic composites. Around 4000 geometrically custom elements are computer generated then digitally fabricated for the complex structure.

The amalgamated system elements can be programmed to significantly compute unusual shapes within wavering humidity reaction ranges by adjusting the subsequent parameters. The fiber direction, the layout of both of the synthetic material and natural material, the length to width to thinness ratio, the geometric elements, and the controlled environment.

Anastasia Andreieva is an accomplished Architectural Projects Editor at Arch2O, bringing a unique blend of linguistic expertise and design enthusiasm to the team. Born and raised in Ukraine, she holds a Master’s degree in Languages from Taras Shevchenko National University of Kyiv. Her deep passion for architecture and visual storytelling led her to transition from translation and editorial roles into the world of design media. With a keen eye for conceptual clarity and narrative structure, Anastasia curates and presents global architectural projects with precision and flair. She is particularly drawn to parametric and digital design, cultural context, and emerging voices in architecture. When I’m not analyzing the latest architectural trends, you’ll probably find me searching for hidden gems in cityscapes or appreciating the beauty of well-crafted spaces. After all, great design—like great connections—can be found in the most unexpected places. Speaking of connections, because architecture isn’t the only thing that brings people together.
