Ever seen a geodesic home? These eye-catching homes don't use rectangular boards and right angles; instead, they use triangles and polygons for windows and other accents.

We spoke with Blair Wolfram -- dome designer, builder, and manufacturer, as well as the founder of Dome Inc. His Dayton, MN -- based company builds 15 to 20 domes per year, so he knows why dome homes are popular with buyers.

One large benefit? Wolfram explained dome-shaped homes are energy-efficient. A sphere-shaped home has a smaller surface area so it's much less likely to lose heat than a conventionally shaped home.

The designer said dome homes also tend to do well in areas with extreme weather thanks to their sturdy nature. Domes flourish around Florida's coastline, he said, because they can withstand a hurricane. And they were trendy in California for a while, for seismic reasons.

"You will see that the dome is by far the strongest shape when it comes to earthquakes," said David B. South, president of the Monolithic Dome Institute.
