It’s a home completely or for most of it’s part off the grid. That means no electricity and water networks. There is nothing to tie it to any utility services, which eradicates dozens of potential problems.
But is the Earthship primitive ? Absolutely not.
It’s true you don’t use any commercial services, but it’s only because you don’t actually need them. The design of this home generates it’s own resources like fresh water, electricity and heating, by using what nature already give us for free. It also involves growing your own food, so in the end you pay no taxes, you spend less or even nothing on food and you live comfortably as a regular 21st century human.
How does the concept achieve all that we’ll explain in this thorough article
As it’s not dependent on the regular services we need to live our lives, it can be built in most locations. You need free space and access to sunlight as it’s key to every system in the home. The concept of the Earthship is simple enough that you can build it yourself, even if you lack the most basic construction skills.
A mid-age couple from Toronto, Canada build one for themselves without the help of anybody else or any construction equipment. What they needed were plans from the building and three months to construct a three-story house, fully equipped for living.
For materials, you can use everything able to categorize as thermal mass. Thermal mass is a concept of architecture design, which allows the mass of the building to provide control over temperature fluctuations.
