How Much Does a Lean-to Cost?

One of our most popular designs is a 30×40 barn with lean-tos on both sides. Typically this would have an enclosed 30×40 main section with 10-foot sides, and two 12-foot-wide lean-tos on each side with 7-foot sides. The total size of this building would be 54×40, with almost 2,160 feet of covered space.


Versatile Uses for Lean-To Metal Buildings

Lean-tos provide extra covered space for parking, storage, or shelter. They can be added to garages, barns, or workshops to protect vehicles, equipment, or animals while keeping access convenient.

Metal Building with Lean-To Porch

Once common use for a lean-to is to add an open or partially-enclosed porch to one or both sides of a building. These lean-to porches can be used to park vehicles or store equipment that needs to be protected from the weather, but that doesn’t need to be locked up inside your garage or barn.

Metal Garage with Lean-To

If you need a three or four-car garage, consider adding a lean-to to each side of your garage instead of designing an extra-wide clear-span garage. A Garage with a lean-to works especially well if you have an RV, since you can make the middle section much taller than the lean-to.

Lean-To Horse Shelter

A lean-to barn makes a good horse shelter, with plenty of space for sheltering horses and storing feed and hay. An open-sided lean-to allows horses to wander in and out at their leisure. By purchasing a lean-to barn, a horse owner can provide shelter for horses without needing to build an elaborate stable with all of the trimmings. For more detailed information about how to create a lean-to horse shelter, see our page about horse shelters.
