National Underground America Day May 14

National Underground America Day May 14


Across North America, approximately 6,000 people who live in some form of underground architecture. On March 14 we observe National Underground America Day.

One of the top advantages to a subterranean dwelling is energy conservation.  Completely covered homes or Earth-sheltered homes are covered on all sides with earth while earth-bermed homes leave one side exposed.  Both allow for more stable temperatures within the home and less exposure to the elements.

There are also some disadvantages.  If you like lots of light and throwing open the windows on a summer day, this type of house might not be for you.  National Underground America Day gives us all a chance to check it out.

Founded by Malcolm Wells in 1974, National Underground America Day recognizes that thousands of Americans dwell within the Earth, not just upon it. Wells (1926 – 2009) is considered “the father of modern earth-sheltered architecture”.

Wells was also a writer, illustrator, draftsman, lecturer, cartoonist, columnist, and solar consultant practiced what he preached by living in a modern earth-sheltered building of his own design.   He took up the challenge of underground architecture as he believed the Earth’s surface was “made for living plants, not industrial plants”.

Retiring in 2004, Wells continued his advocacy for underground living until the end of his life.
