If SHTF and you have to bug out but you have nowhere to go, this may be a valid solution to your situation. This structure or shelter is called an Earth Sheltered Dwelling. You may even want to build one at a bug out location for a spare shelter or you may think this is sufficient as is.
The earth sheltered approach helps regulate the temperature inside even without a heat source. If you build in such things as a Rocket Mass Heater it will take only a minimal amount of fuel to heat your space. Pay attention to the construction techniques on the article.
This style of shelter is easy to build and maintain and because it is natural you won’t need to spend a dime on it. These types of shelter can be easily hidden and camouflaged too.
