Most of the lean-tos are enclosed with walls on three sides and are often left open on one of the sides. This structure allows an individual to be used for a number of purposes. It even provides extra carpet or a space that can be used for a variety of purposes.

You need to decide of how far it will extend from the courage and how long it will run from the side of the garage. If you don’t plan of how much days you require, then you will definitely end up in making it smaller. You need to think about your purpose of making the lean-to and end upon deciding its size. In addition to this, you need to also check that if any building permits are required for building your structure or else you will regret in the future.
  • Step 2: Next you need to do is to holes at least 4 feet apart from the length of what you have decided your lean-to be. It is important that you check with your local builders association to know the frost line in your area and ensure the fact that you dig holes below the frost line so as to prevent the structure from shifting in the cold weather.
  • Step 3: Now, mix cement with a wheelbarrow and shovel. Then set the tubes in the holes so that they stick about 6 inches above the ground. Then you need to pour the cement into the tubes and put the rebar by leaving at least 4 inches exposed at the top. Let the concrete set to its best. Do not do the things in a hustle as it needs to survive for the long future, so let it set.
  • Step 4: Now, you need to drill a 4-inch hole into the four-by-four post so that the rebar fits over it. The whole should be snug enough so that the post is said firmly on the concrete. Now you need to cut the post to the required height and mount them on the piers. Metal garages also proof to be of benefit as you don’t need to run here and there for buying raw materials.

You also need to attach rafter brackets with the help of screws. If you want to have an enclosed lean-to, then you need to screw the floor beans to the outside of the post and walls of the garage.

  • Step 6: Next you need to do is to you nailed the OSB to the roof of the structure. And if you are planning to have walls for your lean-to, then you need to frame the walls and attach them to the roof and floor frame with the help of lag bolts and large screws. Also, ensure the fact that you nail the OSB the outer walls and floor as well.
  • Step 7: Last but not the least, staple or nail tar paper to the roofs and walls of the lean-to. Also, nail the shingles to the roof.

Uses of a Lean-to Garages

A Lean-to-Metal Garage provides several benefits. Several vehicles can be readily parked in your garage. The slender shape of this building allows you to park under one roof your cars, your rental cars, or any heavy-duty vehicle. It ensures your vehicle’s complete safety from unforeseen robbery. It also protects from wind and snows your cars and other things. Your lean structure can also store your inventory that many people choose when they don’t have many parking automobiles.

Foundations of Lean-to Garages

Although most individuals utilize concrete for the floor and foundation of their lean-to-metal garage, there are several additional options. The section below describes several others and highlights their advantages and disadvantages.


Dirt has been here since I remember it, and it is undoubtedly economical – you’ve probably got your land right there. A ground floor works very well for a carport and can even be utilized for a garage, or an outbuilding, as long as concrete floors and platforms support the structure. Bear in mind, however, that when it is dry and muddy when it rains, the floor will be dusty – including a freshly washed automobile that drips may make muck.


The stone spread is not significant, but it is a step up from the dirt. You probably more than require concrete foundations and piers if you have anything other than a vehicle carport. Gravel, though, is a lot cheaper than concrete, so if you’re on a tight budget, you might wish to utilize it as a provisional floor.


Asphalt is a large flooring material, but you may still need concrete, depending on the size of your structure. However, once the foundation is found, the asphalt may be put and makes the garage floor very long and lovely. The material should be screened regularly, much the same as an asphalt driveway.
