Some call it a "dome home," but the technical term is a geodesic dome. And although Dan and Jackie Milligan didn't build this home in Cedar Rapids, Iowa, they're benefiting from its energy-efficient design.
How it works
A geodesic design uses triangles to create a super-strong sphere structure. The shape encloses the most amount of space with the least amount of materials, making these homes very economical and earth-friendly.
Energy savings
Dan and Jackie's home was built in 1989 using a kit. The triangular panels, with 2x6 studs and R-43 insulation, were bolted together to create a 2,700-square-foot house with a finished basement.
Other benefits
The freestanding dome shape allows tremendous flexibility in the placement of walls and the size and shape of rooms. The Milligan's daughters use the nooks and crannies in their bedrooms for storage and play space.
The high open ceiling provides great ventilation and bright sunlight all day long. In the summer, warm air rises along the curved walls and escapes through windows in the top of the dome, providing natural air conditioning. |
