Some call it a "dome home," but the technical term is a geodesic dome.

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.

The most famous geodesic dome in the world is "Spaceship Earth" at Walt Disney World's Epcot theme park.

Benefits

The freestanding dome shape allows tremendous flexibility in the placement of walls and the size and shape of rooms. Nooks and crannies can be used 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.
