1. Boeing 727 Hotel - Costa Rica
This 1965 Boeing 727 was once a working aeroplane which flew people from South Africa to Columbia. However, when it stopped flying it was destined for the scrap heap. That's when it was bought at auction for $2,000 and was transformed into a £300-a-night hotel suite.
2. Hobbit House - Wales
Clearly owned by an avid Tolkien fan, this Hobbit hole in Wales was built for less than £5,000 and took over 4 months to build! It was built with only natural materials by a photographer and his father-in-law.
3. Slide House - Japan
Externally, this is 1,700 square foot property looks relatively ordinary. However, internally this house is connected by a series of slides... perhaps one of the most fun houses in the world too!
4. Clock Tower House - Brooklyn, USA
This apartment is truly unique. Costing $18 million dollars, it's built in Brooklyn Clock Tower building. Set over 7,000 square feet, it offers views of Manhattan, Brooklyn and Queens.
5. Flintstones House - Malibu, USA
A recreation of the famous house of Fred and Wilma Flintstone, this extraordinary home is typical of Bedrock architecture.
