Your space needs can grow over time

You must have had some specific things you knew you needed to store, or you wouldn’t have had metal carports, metal garages, or metal storage buildings installed, to begin with. But as we Americans tend to do, you’ve managed to accumulate even more stuff over time. We get it, because we can all relate on a personal level!

Even so, there’s good news. If you now find that you’ve outgrown your current storage space capacity, thankfully there’s a metal buildings solution for that, especially if you partnered with Carport Central to provide your original metal structure solution. What can you do to transform your current metal building to allow for more storage space, without having to buy a whole new building? Read on to learn more.


What are the benefits of modifying an existing metal building?

Why is modifying your existing metal carport, metal garage, or metal storage building a good solution? First and foremost, you’re able to get the extra storage space or new building application you really need. Plus, it’s usually cheaper to amend your current building than to buy a second, separate building. Transforming your current metal structure can be a very cost-efficient means of getting the amended space you need, and you won’t have to get rid of your existing metal building to do it.

The add-ons and extensions used to expand metal buildings are also incredibly flexible, allowing for whatever additional metal building application you may need. Looking for added recreational space, workspace, finished space, or storage space? Adding on to your metal building can be a perfect solution. And expanded metal carports, shelters, garages, and barns make perfect gathering spaces for hosting social gatherings and company events, too.

This process of expanding your existing metal building can be relatively simple and pain-free, in most cases. Want to install some custom-made metal building kits as a DIY project? Carport Central can help provide for that, as well. Plus, it generally takes much less time and effort to transform an existing building than it would to install a separate, new structure.

How does a metal building lean-to work?

Hikers, campers, and survivalists have been using simple lean-to designs to provide shelter for years, and this same concept can be used to expand the space capacity of a metal building. A metal building lean-to typically involves a simple-slope roof structure which is either attached or placed immediately adjacent to an existing building. For that matter, steel tube-framed structures also make excellent standalone monoslope roof buildings, as well.


Reasons why adding a lean-to addition makes good sense

  • You can extend the dimensions of your building without having to break the bank. If you’re looking to expand or adapt your existing metal building, then one or more lean-to additions can help you get there.


  • Adding a lean-to is a great way to create your own custom metal carport for vehicle parking. Lean-tos can be designed to accommodate everything from passenger vehicles, to motorcycles, ATVs, RVs, boats, tractors, and more.


  • Lean-to structures also make perfect picnic shelters, cookout areas, fire pit areas, and covered play spaces for the kids. They make nice poolside cabanas, too.


  • Use a lean-to structure as a partial-shade gardening area, or even enclose it with clear roof and side panels to create your own personal greenhouse for growing plants, vegetables, flowers, or whatever you like!


  • An enclosed lean-to can also be a perfect solution for adding a new room to your home or business structure. Build your own man cave, she shed, workout room, game room, home office, workshop, or whatever you need.

Popular lean-to metal building categories

What are some popular ways to incorporate a lean-to into your metal building plan? There are many, but here are some of the more popular lean-to metal buildings we provide for our customers at Carport Central:

• Lean-to storage sheds

Most everyone could use some more storage space, and lean-to sheds work great in that capacity, no matter how much space you have to work with or need. If it’s exterior covered storage space you need, a metal lean-to can fit the bill.

• Lean-to carports

Maybe what you really need is some covered space for parking vehicles. A lean-to carport is a perfect solution for that!

• Lean-to garages

Wish you could turn your metal garage into a combination building? You can! Lean-to garages are typically designed as garage buildings with one or more lean-to extensions added on the side. This multipurpose building solution is both functionally effective and cost-effective.

• Lean-to barns

Step-down barns and raised center barns are very popular for farm and ranch usage. With this design, the central building section is flanked by shorter lean-to sections which extend outwards. These lean-to areas can be left as roof-only structures, or they can be fully enclosed to create even more functional barn applications.


Can I add a lean-to to my existing building?

This is one of the most common questions we get from metal building owners who want to expand their buildings. The short answer is yes, absolutely! And the cost of adding a lean-to can be cheaper than building a second, standalone metal structure.

Just note that there is one caveat to keep in mind. Carport Central can typically only facilitate lean-to add-ons for buildings that were originally purchased from us, due to building compatibility issues with various manufacturers.
