The Hex House
Architects for Society
Inspired by advantages of a hexagon's geometric strength and expandability found in nature (beehives, for example), the 2-bedroom/1 bath Hex House is built on-site using structural insulated panels (SIPs), with the ability to add on additional hexagon-shaped rooms into a wide variety of living arrangements over time.
Built Prototype Only

The Hex House is a 2-BR, 1 Ba home that is primarily constructed on-site using structural insulated panels (SIPs). The home envelope arrives flat-packed and can be assembled in a matter of days resulting in an extremely efficient and rigid structure. The Hex House can be used alone, expanded, combined together, arranged into communities, and, ultimately, be disassembled and relocated.

| Professional Engineer Stamp? | SIP construction may require submission by licensed architect or engineer since it deviates from typical wood frame construction. |
| Conforms to ICC’s Temporary Structure and Uses Code | The Hex House would comply and can be constructed for temporary use since it can be disassembled and rebuilt. However, the home is designed to act as a permanent structure. |
| Other Structural/Safety Comments | |
| Sustainability/Green Building Certifications? | The building’s pier foundation system reduces its impact on stormwater management; the tight envelope reduces heating cooling expenses; the home can be integrated with solar, wind, gray-water use, and other green technologies as desired. |
| Materials Used/Made of: | SIPs are sandwich panels consisting of cement board and plywood/ GWB with polyurethane between. Panel materials can be changed to suit conditions. |
