Buying a Metal Garage on Alan’s – Step by Step
Metal garage buildings are great for workshops or extra storage space for anything from farm equipment to arts and crafts.
We offer a wide variety of metal garages, each backed by a one-year workmanship warranty from the installation date.
Buying one is simple. You can do it online with our user-friendly 3D editor. The following step-by-step guide will show you how to choose and customize your new metal garage.

STEP 1
Start With One of Our Popular Steel Garage Buildings
Select one of our featured configurations below to preload doors, windows, and other options shown in the images below. It’ll save you time.
Don’t worry if the garage isn’t exactly what you want; you can customize it later.
STEP 2
Choose Your Garage Size
You can customize the garage’s width, depth, and height. Longer steel garages only work with vertical roofs. If you’re building a residential garage, consider whether it’ll be an attached or detached garage and how many vehicles you plan to park.
Garage Size | Width (ft.) | Depth (ft.) | Area (sq. ft.) |
---|---|---|---|
1-car garage | 12’-18’ | 20’-30’ | 240-540 |
2-car garage | 20’-24’ | 20’-30’ | 360-660 |
3-car garage | 30’-36’ | 20’-30’ | 600-1,260 |
4-car garage | 40’-48’ | 20’-30’ | 800-1,600 |
STEP 3
Choose a Roof Style for Your Garage
You can choose from different roof styles, including regular, boxed eave, and vertical roofs.

Regular Roof Garage
The regular roof style has a bow that gives it a unique shape
- Barn-shaped
- Rounded design
- Most cost-effective option





Boxed Eave Roof Garage
This A-frame roof style has panels that run from front to back
- Similar aesthetic to vertical roofs
- Has horizontally aligned panels





Vertical Roof Garage
The vertical roof style is the strongest roof style available
- Vertical sheeting allows rain and snow to slide off easily
- Ideal for structures over 40 feet to prevent leaks




STEP 4
Choose Your Garage Height
Consider the space available for the foundation and the height you need for your vehicles and other items to fit in nicely.
The following calculator can help you estimate the leg height you’ll need.
Roof Center Brace Clearance & Peak Height
Select your carport or garage preferences to see the center clearance and peak height.
Learn more about height clearance and building heights on our Height Clearance Calculator page.
STEP 5
Customize Your Steel Garage
Decide on the number and size of doors and windows you want. You can also change the color to fit your taste or your home’s color, which is especially relevant if you’re building a residential garage.
Once you’re done, you’ll get a detailed quote. If you agree with the amount, hit the “Buy Now” button.
STEP 6
Get Your Permit
Once you pay the deposit for your custom metal garage, you’ll be able to download the engineered plans. You can take them to your building authority to get your permit.
STEP 7
Prepare a Space for Your Prefab Garage
Before we deliver your new garage, set up a level gravel pad or concrete slab, and make sure the foundation is the right size.

For gravel pad
We recommend your gravel pad to be 2 feet longer and 2 feet wider than your garage size.

For concrete pad
Typically, we recommend your concrete pad to be at least 1 foot longer and 1 foot wider than your garage size. Use our concrete pad calculator to confirm your pad size.
Learn more about Concrete Pads on our Concrete Pad Size Calculator page.
