What Is a Metal Building with a Lean-to Carport?
As shown in the image, it can include garage doors, walk-in doors, windows, and open or enclosed sides, offering customizable storage and shelter options.

Advantages of Lean-to Metal Carports
Convenient Access
Open-sided lean-tos provide quick access to vehicles, equipment, and storage, making them ideal for frequently used items.
Cost-Effective Solution
Lean-tos offer an affordable way to expand covered space while maintaining durability and long-term value.
Customizable Design
From size adjustments to enclosed sections, lean-to structures can be tailored to fit different needs and property layouts.
Weather Protection
Built with strong materials, they shield your assets from sun, rain, and wind, keeping them safe year-round.
Three Types of Lean-To Structures
There are three main types of lean-to structures. Each of these can be paired with different barn styles to create a functional and customized metal building.
Carolina Barn
The Carolina Barn has a tall main section with shorter lean-tos on the left and/or right side of the main structure. Each section of the barn can be open, closed, or partially closed. If you fully enclose the main section it becomes a traditional-looking barn.
The Carolina Barn is a good choice if you need a carport for an RV or tractor and one or more smaller vehicles.
The leg height of the main building should be at least three feet taller than the leg height of the lean-tos.


Horse Barn
The Horse Barn style has a roof that is curved at the edges, which makes it a little more cost-effective than our other barn styles. The side height of the main structure should be at least three feet taller than the side height of the lean-tos on either side. Like the Carolina Barn, each section can be open or closed, completely or partially.
Seneca Barn
The Seneca Barn has a continuous roof with a 3:12 pitch. That means if you have a 12-foot lean-to, the side height of the lean to will be three feet shorter than the main building. If you have an 8-foot lean-to, the side height of the lean to must be two feet shorter than the main building.

Frequently Asked Questions
A lean-to is a simple way to add another structure to an existing building. It’s made by “leaning” rafters against a wall to form an extra roof. Free-standing lean-tos also exist, but these are generally simple structures used as shelter at a camp.
We deliver lean-to buildings to Alabama, Arkansas, Florida, Georgia, Indiana, Kansas, Kentucky, Louisiana, Maryland, Mississippi, Missouri, North Carolina, Ohio, Oklahoma, Pennsylvania, South Carolina, Tennessee, Texas, Virginia, and West Virginia.
Unfortunately we can only add a lean-to to a building at the time it is installed. If you need to attach a lean-to to an existing building, you will need to build it yourself or buy a lean-to kit from a different seller.
Yes. You can add a lean-to to just one side or both sides.
Yes. The lean-tos do not need to be the same width, length, or height.
We can’t add a lean-to on the back, but we can extend the main roof to create a porch on the front or back of your building.
