Another unusual dwelling

I had written about the underground fortress in Blaine, WA (a few miles from the Canadian border crossing) earlier here: A house for sale... Here is one in Colorado for the especially paranoid types. Check out: The Ultimate Secure Home

For Sale By Owner - The Ultimate Secure Home:
Strategically located in the awesome San Juan mountains of Southwest Colorado, this patented steel-reinforced concrete earth home was built to withstand almost any natural or man-made disaster you can name. It is more secure, safe, and functional than any conventional house could ever be, yet still has a level of comfort that one might not expect to find in an underground home.

The house and its 4.3 acre parcel are currently offered at only $475,000 ($20,000 below appraised value). Or $495,000 for the house with a 4.38 acre boundary adjusted parcel.

The rocks around the entrance in the top picture are all made from concrete and painted to look like granite. The dwelling is huge and also features an inner "blast room" built to withstand a nearby nuclear bomb. The equipment at the bottom is an air filter designed for Nuclear, Biological and Chemical air filtration. Quite the hobbit hole... Hat tip to BoingBoing for the link.
