World's Most Unusual Houses o_O

1. Bubble House

The bubble house in Tourettes-su-Loup, France is listed as a historic monument despite being designed in the 70s and being as-yet incomplete. The design is highly futuristic and you might expect from the name it is made up from several 'bubble' shapes give it round ceilings and walls – which is reflected in the curved convex windows and doors too. It also features a range of round pools and waterfalls and if that wasn't enough it's situated on a volcanic terrain.

2. Dal al Hajar

Dal al Hajar in Yemen is one of the world's most unusual houses for sure but it quite different from those designs of Bart Prince. This is really more of a palace than a house per-se, but was designed to be a summer home. Cut straight into the rock that forms its base it is highly tall and narrow in its design and made up from many different layers and levels. 

3. Bart Prince Homes

Bart Prince is an architect who is well known for his unusual structures. These include many unusual homes that break the mould of the box-shaped buildings we all drew as children and are some of the world's most unusual houses. Each home revolves around a central theme, and is designed from the 'inside out'. Bart Prince's own home is of course a testament to this original and quirky design – some kind of metallic snake-like looking building that is suspended in the air and features unusual looking antennae along with some other mysterious features.

4.  Upside Down House

Situated in Szymbark in Poland, the upside down house is essentially exactly what it sounds like – a house that is completely upside down. Looking like any other wooden home apart from that rather distinguishing feature, it was designed to be a statement on 'communism and the end of the world' (whatever that means...). Apparently just standing inside the building can make you feel dizzy and seasick. One of the world's most unusual houses and apparently one of the most sickening and disorientating as well!

5. Toilet Shaped House

Again this is a house that is adequately described by its title – the toilet shaped house is a house that is shaped like a toilet, or more accurately a toilet seat with a distinct lack of cistern at the back. The windows are glass around the outside making for a very spacious and light interior. This masterpiece can be found in Suweon, South Korea.
