Nowadays every household seems to have multiple cars and having a small garage is no longer enough to have your car parked in safety. In fact even with modern houses now being built with extended or double garages, you can still run out of space for your car. Since most people end up using half of the garage for storing a number of other things and many people set up their tools and workshop there, you are not left with too much space to put in more than one car in your garage. This is why you should consider getting carports installed next to your house.
A carport is exactly what you think it will be; a separate area where you can park your car in shelter and safety. This can be a useful area for modern houses, but is probably a necessity for older houses as they are usually built with a smaller single sized garage. Even the existing garages do not really have a lot of space since the household storage is probably placed there as well, so carports might just be a smart investment.
You can get a variety of choice when getting carports installed. You should obviously consider what design will look good with the general design of your house, and also check how much space you have, before you commit to a certain design. But you can generally get anything from a basic free standing carport; that will be a covered area with no walls where you can park your car in the shade, to more expensive options like flat roofs and walled or curved roof carports. The completely covered carports are a much safer option to have; you can easily have a double covered parking space that you can lock at night to keep your cars safe.
