There is something known as a tandem garage, that is being included in the construction of a large number of new homes being built. The idea of the tandem garage is a good one, but, unfortunately, it is not very useful for most families. The unique feature of a tandem garage is that it allows cars to be parked one in front of another instead of side by side. Whenever you need to use the car in front, you have to pull out the one in back. So, what many homeowners have chosen to do instead, is park only one car in their tandem garage, leading to an entire garage full of empty space.
