An underground earth home is a home that is built completely below ground or under grade. Generally, underground earth homes have a central atrium to which all glass windows and doors point, allowing for light, solar energy and a stairway access to ground level.

However, disadvantages such as rain drainage and snow removal should be considered before building.

A bermed earth home may still be partly below grade and has earth covering one or more walls. Typically, the home has all but one wall covered in earth to allow for energy-efficient insulation and protection from elements. The exposed wall usually faces to the south, providing sunlight and heat from the sun. Some bermed designs cover all four walls and the roof with earth, leaving only the doors and windows uncovered.
