Our 2 Car GarageHouse Plan collection includes plans that have enough space for two cars to comfortably fit inside. We have plans that have attached garages, as well as detached garage building plans. The square footage of the garage space is not included in the finished square footage of our house plans. Common garage sizes are 20x20, 20x22, 24x24, and 24x30 feet. Attached and detached garages follow the styles of the home including traditional, craftsman, modern, etc.
