These kind of weird looking homes don’t exactly fit into those perfect little neighborhoods you see when walking around a cute downtown area or a clean-cut suburban gated community. But Buckminster Fuller saw the potential is those triangles: With the goal of creating a structure analogous to nature’s own designs, Fuller began to experiment with geometry in the late 1940s. In 1951, he patented the geodesic dome, and while you may not see a lot of on a normal city street, geodesic domes are known to be the most efficient building system available. So, why should you want a dome home anyway?
The sphere is nature’s most efficient shape, covering the most living area with the least amount of surface area. When compared with a similar sized rectangularly-shaped house, the dome home will have 30 percent less surface area. A dome home will actually use about 1 /3 less lumber to build than a similar sized box house, according to Linda Boothe, owner of Oregon Dome, so even though the dome uses less material, it’s about five times stronger than a rectangular-shaped house. Additionally, a third less surface area means that a third less heat is transferred to and from its surroundings, saving the average dome homeowner about 30 percent or more on their average heating and cooling bill.
Well, just about. When the Loma Prieta earthquake in the Santa Cruz mountains hit in 1989, it hit 7.1 on Richter scale and over 500 conventional homes in the area were destroyed or needed extensive repair. Many more were damaged or needed major repair after the aftershocks rolled through. The only home to survive that quake in the area was an Oregon Dome geodesic dome home, Boothe said, and it was set up as a shelter for local earthquake survivors. Time and time again, dome homes have survived earthquakes, tornadoes and hurricanes when all other homes were destroyed. Why?
According to Boothe: “You can begin to see the intrinsic strength of this design by trying the following: Nail four boards together replicating box house framing and then nail three boards together in a triangle. You’ll find you can easily bend, twist, and skew the conventional square shape into many different shapes. This is what happens to your house in an earthquake. Now try to change the shape of the triangle. You can’t. The triangle is the strongest shape.”
