A metal garage with a lean to is one of the simplest and budget-friendly ways to add covered space without jumping to a bigger enclosed building. You get protection from rain, snow, and harsh sun, plus a better way to drive in and out without worrying about an overhead door or rain hammering down on you.


If you’re comparing lean to styles, these four layouts cover most real world needs:

  • Side lean to (most popular)

  • Lean to on both sides

  • Front lean to

  • Wrap around lean to (most customized)


Below is a breakdown of what each layout is best for, what to consider, and a few upgrade options that can make your lean to look fully finished rather than basic.


1) Side Lean To: The Everyday Workhorse

A side lean to is the most common setup because it fits almost any property and solves the biggest pain point: you need more covered space, but not necessarily more enclosed space.


Brown and gray metal garage with side lean to, set in a grassy, tree-filled yard under a clear blue sky.

Main Building Size:

[24'x25'x10']

Lean-to Size:

[10'x25'x6']


Best for

  • Covered parking when the main bay is full

  • A shaded outdoor work area for projects that kick up dust or fumes

  • Storing a trailer, mower, UTV, or materials without clogging the garage


Why it works

  • Keeps the main building footprint simple

  • Adds usable space along the full length of the building

  • Easy to position it on the side that takes the worst weather


Popular add ons

  • 3' side paneling to cut sun exposure

  • Vertical roofing panels for better drainage

  • Finished legs if you want it to match the building




2) Lean To on Both Sides: Balanced Coverage


A lean to on both sides is the move when you want serious coverage but still want to keep your enclosed building width reasonable. It’s a strong option for owners who dedicate the main area as a work space and place equipment and vehicles outside in a covered space.

Main building size: [20'x25'x10']

Lean to A size: [10'x25'x7']

Lean to B size: [10'x25'x7']

Best for

  • Extra covered parking on one side and a work or storage zone on the other

  • Separating clean and dirty uses (vehicle storage vs equipment or materials)

  • Homeowners or farms that need covered space on both sides year round


Why it works

  • Adds function without forcing a big enclosed span

  • Helps keep the main interior dedicated to the work that needs to stay inside

  • Gives you layout flexibility if your driveway or access comes from multiple directions


Design tip

If snow and heavy rain are part of your normal season, plan the lean to placement so your most used access paths stay covered.



3) Front Lean To: The Covered Entry That Changes Everything


A front lean to is all about access. It creates a covered zone right where you load, unload, open doors, and walk into the building. If you’ve ever fought wind-driven rain or stomped snow off your boots at the entry, you already get why this layout matters.

Main building size:[40'x50'x14']

Front lean-to Size: [10’x20'x8']

Best for

  • A drive up drop zone in bad weather

  • Keeping the main entry and side entry door protected

  • A place to stage tools, materials, or deliveries without dragging everything inside


Why it works

  • Cleaner entry experience in rain and snow

  • Helps prevent water and slush from getting tracked inside

  • Adds curb appeal because it changes the whole front profile of the building


Upgrade options

  • Finished legs to match panel color

  • Dutch corners for a clean finished gable look

  • Covered gable ends so it looks integrated, not tacked on



4) Wrap Around Lean To: Maximum Coverage and a True Outdoor Work Zone


A wrap around lean to gives you that covered porch feel, but built for real work and real weather. It’s the top option when you want multiple covered sides for parking, work space, and protection around the building.

Main building size: [40'x80'x14']

Lean-to size:

[10'x50'x9']

Best for

  • Owners who want covered access on more than one side

  • Creating a large outdoor work area with airflow and shade

  • Properties where weather hits hard from different directions


Why it works

  • More protected entry points around the building

  • More flexibility for vehicle parking, equipment storage, and work flow

  • Turns the building into a multi zone setup without more enclosed square footage


Where it shines

  • Snow country, where you want a covered zone to walk and work

  • Hot summers, where shade and airflow matter

  • Busy households and shops that need multiple dump zones around the building


Why Lean Tos Are a Smart Add On


Lean tos earn their keep fast because they solve daily problems:


  • Quicker to leave and enter through a covered access point

  • Shelter when weather is inclement, especially rain and snow

  • Place for patio furniture during harsh summer sun

  • Covered outdoor work area when you want fresh air


They are also typically more cost affordable than building a wider enclosed building just to gain space.


Pitch and Panels: Built for Drainage and Snow


Most lean to pitches are commonly built in 3:12 and 4:12. For performance, we recommend vertical roofing panels, and for heavy snow regions, aim for a 4:12 pitch. You can also upgrade to our 50 PSF snow load.


  • Efficient drainage

  • Reduced snow build up

  • Better long term weather performance
