There are plenty of homes that have a one car garage, plenty of space around the house and three or four cars to go with it. One car gets to live the life of luxury why the rest of them are left to sit in the sunlight or bask in the glory of a mud bath when bad weather rolls around. If you have the space, why not install a carport of some type and actually create another garage.
When you are shopping for a carport, there are plenty of reputable companies that you can use. Carports comes to mind first as they have a complete line of carports and many other structures as well. Best Carports is another company that is known for both quantity and quality in carports. Whether you want a portable carport or something more permanent, you will be able to find it with either of these companies.
When getting a carport installed, you can either hire a professional to do it for you or you can get buy carport kits that will allow you to install it yourself. If you have some DIY experience, you may find this project a nice little challenge to do over a weekend. As long as you have the tools and some contracting experience, you should be able to handle this task pretty easily.
