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


4 residents / 2 bedrooms

$12,500 / resident

Long-Term/Permanent (15+ years)

50 days offsite 10 days onsite

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.

Intended use cases The Hex House can be designed into various interior configurations to be used as ADU, ICU or medical room, homeless housing, summer home, primary residence, and office/ classroom .
R-value (insulation) 31-40
Risk Category II
Roof Load (PSF) 40
Indoor Clearance Height (ft) 12
Waterproof? Yes
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.
Mobile? [mobile]
Disassembly/Assembly Comments: The home can be fully assembled and disassembled in a matter of days.
Ideal Mounting Surfaces Soil (Dirt/Grass), Asphalt / Parking Lot, Other
Anchoring Process The foundation is designed to use helical piers which attach to a system of beams. SIP’s are connected to beams using cyclone rods. Piers can be modified for seismic conditions.
