These are five of the coolest converted homes

It's not uncommon for old buildings to be converted into something else. Transforming one unique space into another is a favorite of architects, interior designers and designers alike. It gives them the opportunity to preserve the structures character and history while giving it it's own new, unique flair. Take a look at our top five spaces that have been creatively converted into homes.

1. This secret Cold War bunker was originally built to withstand a nuclear war. The five-bedroom London bunker is the perfect combination of luxury and history. This bomb shelter was built by the government in the early 1950's as a place to run the country incase there was ever a nuclear war. It was never needed and was subsequently neglected for years before turning into a luxurious home with a beautiful glass ceiling and indoor pool.

2. Dutch architects transformed this old Catholic church into a modern and spacious home. Since 1991, there were no longer services in the church and up until 2007, the church was used as a showroom for antique furniture. Now, it has beautiful stained glass windows that reflect off the walls and offers plenty of space for large gatherings.

3. Back in the late 1800s, a water tower was built on Sandringham Estate, which was Queen Victoria's summer retreat destination. The water tower has since been converted into a two bedroom home that visitors can pay to stay in for a weekend retreat.

4. This converted firehouse was once the home of Engine Co. 256 in Brooklyn, and has also been a bomb shelter and production studio for Spike Lee. The two bedroom home comes with a skinny kitchen and a beautiful rooftop deck.

5. A train that used to run through Essex, Montana in 1941 was converted into a special room at Izaak Walton Inn. The little red caboose can host four people, and is the perfect stay for any train enthusiast.
