![]() If you don't completely prevent bulk water infiltration and moisture infiltration, your home will be a complete dissaster.Īs for location, yes, very important. It is just a lot more risky, a lot more complicated, which translates into cost. I think we agree on one thing, as you say "with the right plans" you can of course build underground safely. Have a look at " The complete book of underground homes" by Rob Roy.ĭaves Hobbit Home build on Facebook, or you can Google "undergroundandlovinit". ![]() then i am expected to believe that it is cheaper to go the extra step and build an entire second floor ABOVE THAT with all the pretty adornments that go with ot ? Shingles, siding etc. i am pouring a basement, putting a roof on it, and burying it. 18 different architects to get the plans drawn up properly, and even then the first concrete company STILL ARGUED that i do not need to insulate the footings of the Hobbit Home - if you don't, you get mold and mildew along the bottom of the wall.Īnother idea i hear alot of, is that it is more expensive to build an earth sheltered home than a regular one. I am currently building a Hobbit Home in Ontario Canada, and i know from my solar water heater input thermostat that the water temperature 4 feet underground is ALWAYS 45 degrees. With the right plans, the right location and making sure you have a continuous layer of insulation all the way around the building envelope, the exterior temperature should not matter to the building. Not sure if this question is still active after 8 months, but i just have too say, you can build a warm, dry earth sheltered Hobbit Home, regardless of your climate zone. Have a read on that Earthship page and come back with any questions you like, we are more than happy to help. I hate to pop your bubble, but better now that when its too late. ![]() I get the appeal, but it just doesn’t stand up to any modern standard of what we would call ‘green home building’. Building into the ground can offer a lot of benefits of balancing temperatures in both summer and winter, but it absolutely must include ‘actual’ insulation if what you are after is to be in any way classified as an energy-efficient house. If it sounds like I am trying to dissuade you from doing this. It made sense in the historical times you mention, because they didn't have manufactured insulation, which insulates about 10 times better than dirt. ![]() If you plan to keep the home above the temperature of the earth (as in above 50☏), then the ground will not be an insulator, it will be a heat sink endlessly robbing you or warmth. It is a huge step up from winter camping, but an equally huge step down from an efficient home in modern times. We cannot tell you the exact winter ground temperature in your region but I would be suprised if it was as high as 50☏, which is much lower than what would be considered a livable indoor temperature in modern times. Earth can act as an insulator from frigid winter air temperatures, but only up to the point where the air temperature in your hobbit house reaches the temperature of the surrounding earth. The main reason Earthships are a flawed design is that the Earthship corporation seemingly does not have a good grasp on the basic laws of thermodynamics. Why Earthships don’t work in cold climates A Hobbit House would follow the basic principles of an Earthship, so I would recommend you read this page first – Dirt *can* work as an insulator for homes, but it is important to understand how, so you understand its limitations. An earth dwelling or ‘hobbit house’ can have a lot of appeal, but there are many drawbacks that you should know about before building one.
