If you've always wanted to spend the night in a concrete bunker, there's a tiny vacation house in the Netherlands that is ready to make your dreams come true.
This concrete bunker, part of the Dutch wartime defenses during World War II, has been sitting unused ever since. Belgian studio B-ILD undertook to turn it into a vacation home that would accommodate four people, quite the challenge since its interior area totals only 9 square meters (97 square feet).
There are quite a few creative solutions here — pretty much everything in this little home does double duty. Bunkbeds line two walls, and the top bunks fold up so that the bottom bunks can be used as couches during the day. A table (pictured above) folds out from the wall, and the stools can serve as seats, nightstands, coffee tables, or steps to access the top bunks.
Aside from the furnishings, the architects made very few changes to the interior, keeping it true to its wartime origins. They did squeeze in a tiny, barebones kitchen, complete with tiny sink. And outside there's a deck for eating, or just relaxing and enjoying the sun. No word, though, on how you are supposed to use the bathroom. So if roughing it isn't your thing, you might want to look elsewhere.
