The biggest house in the world is actually located on the smallest continent in the world. It is located in Berkshire County, England. Does that give you a hint as to whom this house belongs to? Well, if you guessed Queen Elizabeth II, you are certainly correct!

Queen Elizabeth has lived there in Windsor Castle since the 1950's, and she also owns two other huge properties which you have probably heard of as well: Buckingham Palace in London and Holyrood Palace in Edinburgh.
Maybe you think that since Windsor Castle is a castle, it should not count as the biggest house in the world. However, it is someone's home; therefore, it certainly is a house! The entire area of this house comes out to 46 thousand square meters!
Not only is this house huge, but it is quite old as well. William the Conquereor built Windsor Castle in the 11th century, back when it was primarily used for defense purposes. As the years have passed, various residents of the castle have added on and changed some of the settings in order to reflect their own styles. Windsor Castle is open for tourists, although some of the parts of the castle are seasonal.
