Our Io-20 makes an ideal studio rental unit. This Monolithic Dome is an oblate built on a 3.5-foot stemwall. It has a diameter of 20 feet, an overall height of 10.5 feet and a living area of 314 square feet. A few years ago, Monolithic established a successful rental program that includes a complex of Io-20 cottages in a gardenlike setting. Four main reasons account for its success:

1. For low-income singles, the Io-20s put a clean, affordable roof over their heads.
2. For the landlord, these small domes provide much needed, but easily managed and maintained rentals.
3. They are energy-efficient – so much so that the cost of electricity could be included in the rental fee.
4. Because they are Monolithic Domes, the Io-20s have the innate ability to resist natural disasters, such as tornadoes, hurricanes and earthquakes, as well as fire, termites and rot.
