Have you ever wondered what it would look like if all your vehicles were neatly tucked in a strong, spacious, metal triple-wide garage? Wouldn’t it be nice if you didn’t have to worry about bad weather, crowded driveways, and household clutter taking up the floor space?
Introducing a steel 3 car garage structure! It’s not just for parking, but also a smart investment for homeowners, farmers, and businesses. You can now protect your cars, store equipment, set up a workshop, or a personal retreat space to spend some solo time.
But, before you start building a three car metal garage. It is important to plan wisely. This guide will walk you through the key things to consider, such as size, materials, customizations, and budgeting, so you can make the best choice for your needs. Let’s begin.
Why Choose A 3 Car Metal Garage?
A 3-car parking garage can be used to store household clutter, everyday cars, farm tools and machinery, tractors, and much more. It could be your hobby area, extra space for vintage motor collection display, or space for DIY fun projects alongside parking.
Metal parking buildings are highly durable, super strong, and require low maintenance. They can handle bad weather, resist pests, and don’t need frequent deep cleaning as metal is a non-porous and dense material that doesn’t let mold spores penetrate deeper.
Choosing The Right Size For Your Steel 3 Car Garage
Standard Size: Typically, a 3-car parking space is about 30×20 ft. for sedans, but greater for SUVs and pickups. Before picking up the size, think about your vehicle size, storage needs, and workspace. Ensure to have proper clearance for larger vehicles like RVs or trucks. Extra ceiling height will let you install an overhead ceiling or create a false floor/ loft area.
Door Size And Placement: How big is your car is and how easy will it be to get in and out of the garage? Have answers to these two questions for a hassle-free parking. The answer will be different for each owner depending on the type and model of vehicles they want to park.
Use Vertical Storage: If you want extra shelves, cabinets for storing tools, paint, car supplies, or hanging tools, getting a higher wall will be a great choice. A taller garage lets you have vertical space for storing bikes, sports gear, and seasonal decor.
Key Considerations Before Buying A Triple Wide Garage
A. Determining The Needs – Before buying 3 car metal garage, ask yourself, what do you want to store? Will it be for cars, tools, equipment, workspace, or a living area? Will you need extra space in the near future for a workbench, shelves, or a hobby corner? If so, choose a little extra space.
B. Budgeting For 3-Car Garage – A metal 3-car parking garage can cost you about $15,000 to $60,000, depending on the customization, size, material quality, and location of installation. Include additional soft costs, such as electrical work, home loans, permit fees, construction loans, and personal savings.
C. Check Your Local Regulation And Permits – Check your local county or city rules before selecting garage design. Every municipal department has its own requirements and restrictions, like how far the garage must be from the boundary, your home, or an existing building.
Next, get a permit before starting off construction project. You can ask your metal building dealer to provide you blueprint of the garage design for approval.
D. Site Preparation Is Crucial – After you have secured the permits, order your garage building and start preparing the site. Start by removing any debris and leveling the ground for installation. We recommend a concrete slab for a triple-wide steel garage as it is permanent, strong, and more durable.
Tip: Make sure the concrete slab is at least 1 inch greater than the perimeter (from all sides) and has at least ¼ ¼-inch slope around the edges for better drainage.
Exploring Your Metal Garage Customization Options
A. Roof Styles And Pitch – The choice of your roof will affect looks, cost, and how good it can handle bad weather situations. Common roof styles for steel garages are:
- Regular – simple, affordable, suits moderate weather, and small garages.
- A-Frame/ Horizontal/ Boxed Eave – traditional appeal, suitable for building less than 30 ft. wide.
- Vertical – best for all weather conditions and larger metal structures. It can handle extreme weather like heavy snow and rain, strong winds, and storms.
Generally, a roof’s pitch is between 3/12 and 6/12 (steeper), depending on local building codes, garage style, and climatic regions.
B. Accessories – Most metal garage dealers offer the following custom features that you can add to a metal parking building to increase functionality and aesthetics.
- Doors – roll-up, frame outs, automatic doors, and walk-in doors for quick access.
- Windows – for natural lighting and airflow.
- Insulation – to prevent condensation and heat transfer to and from the building.
- Ventilation – for fresh air circulation and to reduce humidity.
- Electrical Wiring – add lights, outlets, and EV charger.
- Storage Solutions – built-in shelves, attic space, workbenches, cabinets, and rolling carts.
Working With A Three Car Metal Garage Provider
Choose A Reputed Dealer: Research online and in your neighborhood to learn about various metal building dealers, look at reviews and ratings, and ask for a free quote to compare pricing and what’s included in the quote, before you buy a garage building.
Clear Communication Is key: Be specific about what you want, especially size, features, and layout, when designing.
DIY Vs. Professional Installation: You can build it yourself, but since a 3-car garage is a large structure, we suggest hiring a professional crew for the best job. Some metal garage builders include shipping and installation service in their final quote. So, read the quote carefully.
Warranty And Customer Support: Always read the fine print to know if the garage has a warranty and if the manufacturer offers after-installation services. You may get warranties, such as a 1-year workmanship, 10-year on panels and trim, 20-year rust through, and 20-year limited warranty on certified vertical roof style units.
