Check Out the House of ‘Bioclimatic Troglodyte’ — A Home Hewn Out of Rock!

Until the 20th century, many people in the Saumur region of France could be found essentially living in a cave. The cave homes were made from rock carved during the quarrying process.
While it became less popular with more modern conveniences, Fair Companies showcases the updated cave home of one man who has found it inexpensive and comfortable to live in a home carved out of rock.
Fair Companies reports:
[...]
there are over a thousand miles of underground tunnels and thousands of caves, known as “troglodytes”, homes, hotels, restaurants, museums, wineries, farms (silkworms, mushrooms, snails) and even a disco and a zoo (for nocturnal animals like bats).
What makes this land so perfect for underground dwellings is its very malleable rock. 100 million years ago, this part of France was covered by sea. When the water receded, it left a layer of tufa, or tuffeau, a type of limestone that turned out to be ideal for building castles, churches and homes in the surrounding area during the Middle Ages.
All of this quarrying created lots of tunnels and caves that turned out to be ideal homes, especially for quarrymen.
Watch the footage of Henri Grevellec who bought a condemned cave home in 2000 and has updated it since for his own family:
Grevellec says that homes like this are not expensive to buy but that he has made improvements “here and there” to update it for more modern living. The rock, Grevellec says, keeps the home cool in the summer and mild in the winter. Fair Companies refers to the home as “bioclimatic troglodyte” for this reason.

Grevellec made things such as the skylight and extra windows in the rock to improve ventilation and light.
Fair Companies reports that Grevellec’s home is actually six individual cave homes, which he is working to connect or use for other purposes, such as a wine cellar.

Posted on January 3, 2012 at 8:48pmRadon is usually only a problem if you build your house on top of granitic rocks. This is limestone.

Posted on January 3, 2012 at 1:13pmI can not pick up a rock on USA BLM land because of endangering the environment, but it is eco-cool to carve a house out of rock…..??? The double talk of the eco/enviro/EPA hacks is sickening….

Posted on January 4, 2012 at 9:49amYes, when you live in a country where they say it is more environmentally friendly to ship in rock from another region to build a road than use the local rock, you have to wonder what is the definition of environmentally friendly. Is it more environmentally friendly to dig into the earth, or cut down a tree, move it across state, and build where it will get blown down by a hurricane and litter the land? These homes should be mandated by the EPA…

Posted on January 3, 2012 at 10:14amLiving in South Louisiana I guess I could make an underwater cave LOL. There are some advantages of this type of home and with some work I do not think you would really know the difference one you are inside than any other “normal” house.

Posted on January 3, 2012 at 9:45amIf possible I would love to have a home like this in my area. Once structural reinforcement is completed there would be very little maintenance required. It would be difficult to catch on fire. Also your heating and cooling bills would vastly reduced. Of course there would be a lot of headaches running plumbing pipes, electrical cabling, and heating ducts.

Posted on January 3, 2012 at 10:04amI would think that running the plumbing for the most part behind a well structured chase wall that kitchen and bathroom cabinets and sink counters are attached. Making the chase accessible to make repairs and maintenance less costly. Would tie up usable floor space, but I can see where the the savings in the long run would be beneficial.

Posted on January 3, 2012 at 9:50amIn Australia they do this in opal mines. So when you dig out your house it pays for itself in all the semiprecious stones you find. Unfortunately, I live in Oklahoma and we have clay and a high water table making below ground living nearly impossible. I don’t even know of a single home here with a basement. However, we can make brick homes with all our red dirt.
