Delivery, certifications & load requirements
This 20x30 carport garage combo gives you 600 sq. ft. of mixed-use steel space for vehicle coverage, enclosed storage, tools, lawn equipment, farm supplies, motorcycles, ATVs or weekend projects.
The 20-foot width works well for a home driveway, backyard, farm lot or side yard. The 30-foot length gives you room to split the building between open-air parking and enclosed storage, depending on how you want the layout built.
Shown in Evergreen with White trim, this combo building has a 9-foot height, regular roof, one 8x8 garage door and one standard walk-in door. The garage section gives you a locked space for tools, equipment and belongings. The open section gives you quick covered parking for a vehicle, mower, trailer or supplies you use often.
Every building is custom made. You can change the size, height, colors, roof style, garage door, walk-in door, windows, side panels, anchors, insulation, panel layout and certified wind or snow options based on your property and local code needs.
Delivery and professional installation are included. Call Garage Buildings to get your 20x30 carport garage combo quote.
