This design allows cross-ventilation and access to natural light from more than one side of the house.
Are berm homes pros and cons?
Pros and Cons Protection from the elements. Energy conservation and consistent indoor temperature. Privacy since earth-sheltered homes have few windows. Soundproofing against neighbors and nearby roadways. Extra green space and insulation provided by a living roof. Low maintenance, little to no exterior materials.
Are berm homes safe?
If the home has a southern exposure, that’s even better because the sun can use the sun to naturally heat the home.

What are the advantages of earth sheltered buildings?
As such, earth sheltering takes advantage of passive solar building design, reducing the need for energy-intensive heating and cooling systems. The earthen walls also protect against cold winter winds and limit the escape of warm air through gaps around windows and doors.
