About This Quiz

Do you know the difference between vinyl and aluminum siding, or what ducts are designed to carry? Know why you need special electrical outlets in your bathroom, and what these special outlets are called? Any idea what a board foot is? If you think you know all the steps and materials involved in building a house, take our quiz to prove it!

Home building has come a long way in the past couple of centuries. As early Americans established homesteads, they had limited options to choose from when it came to building a house. Most took advantage of plentiful free lumber, joining forces to build simple structures with just a single room or two, using mud to fill the gaps and keep out the cold.

Of course, things have changed a lot since then. Modern homes come equipped with conveniences our forefathers could only dream of. This is pretty nice when it comes to taking a hot shower or flipping on a light switch when the sun goes down, but it makes the building process infinitely more complex. Today's builders are also subject to countless building codes and safety regulations to protect occupants against everything from radon gas to fires to structural failure.

Still think you're a home building expert despite the complexities of the modern construction industry? Take our quiz to find out!
