Underground Fortress
WOw, this is something you’ve got to see to believe. This house in Pacific Northwest of the US, has got an underground fortress going down to 45 feet (15 meters)!

Taken from the website:
The fortress has over 1600 sq. ft. of living area, plus hundreds of more square feet of passages and secrets rooms. It was all hand dug over a 20 year period, and all the walls were constructed with a small electric hand cement mixer. There are 3 ft concrete walls, using 5-bag cement (20% denser than regular cement). Not only are the walls thick and dense, but the finishing work is amazing quality.
There are tons of photos of this place, showing the features like toilet with hot water, gas powered generator with battery recharge, office and living space, loads of secret compartment and can even act as a bomb shelter.
You’ve got to wonder, how much would that unit cost on the market?
