Under the guidance of David Mah, Carl Koepcke and Marshall Prado from Harvard Graduate School of Design created a system for constructing a rapidly deployable ice shelter using snow and ice as building materials. The temporary shelter is intended for cold environments and utilizes the insulative properties and inherent compressive strength of the proposed building materials to craft a spatial catenary volume.

Using parametric modeling and digital fabrication techniques, plastic panels define the framework for the shelter and are joined to make the inflatable structure. Such panels supply a lightweight and packable guideline for the shelter, allowing users to carry the system in a large backpack until construction is necessary. “Instead of using traditional igloo construction, the proposed process could be self-forming under wet, frozen conditions,” explained the designers.
The self-supporting thinwalled shelter builds upon earlier research on pneumatic structures as form-finding and space-making devices. The final product has sectional variability within the catenary structure to optimize multiple interior and exterior spaces. This form utilized internal air pressure and catenary diaphragms define and control the desired inflated shape.
“While fabric reinforcement was used to strengthen and connect the catenary ribs, it was discovered that an ice shell of approximately ½” was capable of supporting itself without further bracing,” explained the designers.
