Best Way to Frame and Insulate a Shipping Container in a Mixed Climate (-30°C Winters, +30°C Summers)

Hi guys,

Starting the process of building out a shipping container storage unit on my property and want to make sure it's done right and has an airtight envelope that isn't prone to moisture, condensation, mold, etc.

I was wondering what the best way to frame the inside would be. I've heard from suppliers that some use metal studs, some glue them to the shipping container walls, and others use 2x4s. In all cases, they use spray foam to insulate/vapor barrier. Would then finish the interior with 1/2" bare plywood. The floor would be a bit different using rigid foam insulation, wood block spacers, and 1/2" plywood floor maybe with an epoxy finish. Spray foam thickness would vary from 2" on the walls to 2.5 or 3" on the ceiling.

Is there a best practice here? I'm mainly concerned about condensation and mold in a climate with -30 winters, +30 summers, and high humidity.

In terms of interior climate control would be running a mini-split, radiators and a dehumidifier.

Any input is appreciated. Thanks!

Looking for info on “cross-stacking” a 40’ box across two at the end like this?

If anybody has had experience cross-stacking a 40’ at the ends like this, would you mind if I picked your brain? Trying to gauge roughly what beam size I’d need to run in between for clearspan.

My container home just left the factory 🚛

This is my unit getting loaded up today. Been waiting months for this and it's finally happening, bigger in person than I expected honestly.

Watched them wrap it up and crane it onto the flatbed. Seeing it swinging in the air was kinda nerve-wracking. I’m gonna live in it, lol.

Now just waiting for it to reach my land, still gotta sort the foundation before it's move-in ready.

Anyone else done this for personal use? How long till you actually moved in after delivery?

Refrigerator container floor!

I’m in a bit of a pickle, I’ve put a down payment on an old refrigerator container to use as my workshop and I was walking inside today and noticed the floor was like walking on a water bed! It seems the floor has come away and water is inside.

Is this something I should be worried about?

Has anyone removed these kind of floors before?

Should I continue with the purchase or am I better to look for other options?

Any feedback would be super helpful! Thank you!

Secluded Container BNB with the Coolest Design

When you have a 6m container, and a stunning spot, what do you do. We helped create this beautiful BNB in Western Cape South Affrica. The outdoor kitchen is part of the container with a high-end bathroom and bedroom. The idea is outdoor living. Wood fired hot tub, long walks, and serious relaxation.

The BNB is completely off grid with solar power, Spring water and composting toilet.

Container units are up - meh

Finally installed. It took 3 weeks, not 2, and they swapped the roof color at the last minute because they had “no stock.”

Ground wasn't flat so leveling cost extra, nobody mentioned that upfront. Seams look rough up close, windows smaller than expected.

Cheap and functional, but it looks nothing like the renderings they showed me.

Anyone else hit hidden costs on these, or just me?

Would you go glamping in a converted shipping container?

White Birch and Sapling are our two BOMA shipping-container stays near Littleton, New Hampshire—one built from a 40-foot container and the other from a 20-foot container.

We wanted to keep the industrial container character while turning each one into a comfortable place to stay, surrounded by White Mountain views. It also gives people a chance to experience container living before deciding whether they would ever build one themselves.

Which would you choose for a glamping trip: the larger 40-foot White Birch or the cozier 20-foot Sapling?

The most expensive container mistake usually happens before the box hits the ground

I work around containers, so take this for whatever it’s worth. Not selling anything. This just comes up a lot.
Most of the bad delivery stories I hear aren’t really about the container. They’re about the 20 minutes when it comes off the truck.
The ground looks fine until it rains. A loaded tilt bed is heavy, and your lawn/soft driveway is not as solid as it feels when you walk on it. If the driver gets there and says nope, that’s usually a wasted trip and another delivery fee. Gravel, mats, or plates on the soft part can save you.
Also measure the runway. A tilt bed doesn’t just magically drop the box straight down. It slides it off while the truck pulls forward. You need a straight shot, usually about another container length behind where you want it. Not around a curve. Not “we’ll make it work.” Mailboxes, fence posts, tight gates… dumb little stuff can kill the whole delivery.
Branches are another one. A 40ft high cube is already 9'6", plus the trailer height. People clear the driveway at eye level and forget this thing is coming in way taller.
And get the box level. Like actually level, not “looks fine.” Support the corners on solid ground. If it sits twisted, the doors can bind and then you’re fighting it forever. If anything, I’d rather have the door end a hair high than sitting low in water.
Last thing: decide which way it faces before the driver starts backing in. Turning it later is a pain. Think about where you’ll walk, where the doors should open, where water/snow goes, all that boring stuff.
The container is usually the easy part. The site is what causes the expensive surprises.
What’s your access like — straight shot in, or are you working around a turn?

Went to check out a "fold-flat container" factory today, low-key impressed

My buddy dragged me to see this "quick-build container" place. It was raining the whole time we were there (that puddle on the ground in the pic is real, not edited), which honestly turned into a decent stress test — seams were tight, didn't spot any leaking.

They had two units stacked on site like a mini duplex. The bottom one had a solid steel door with a normal handle and lock, way sturdier than I expected. The guy there said it unfolds in under 20 minutes with just two people, no crane needed — didn't get to see the actual demo though, wrong day for that.

Honestly went in thinking it'd just be some flimsy tin box, but standing next to it in person changed my mind a bit. That brownish trim also looks a lot less "job site trailer" than the last place I checked out.

Anyone here actually owned one of these long term? Does the fold-flat/no-crane thing hold up after a full year of weather, or is that just showroom talk?

Roof Between Containers

I have two high cube containers with 24' clear in-between them. I want to roof over this space to have a sort of pole barn to park equipment under or do odd jobs with protection from sun and rain. Eventually, I'd install solar collectors on the south-facing roof slope and collect rainwater off the north face.

I found this product: https://korejetmetal.com/product/outdoor-storage/40ft-x-36ft-container-roof-kit-heavy-duty-steel-shelter-no-containers/ but it's only available for a 20' gap between containers. It also looks kinda sketchy and I wonder if it would even work as expected if I moved my containers 4' closer to each other.

My questions:

  1. Has anyone used this Korejet Metal product? If so, how did installation go for you?

  2. Any other ideas on how to economically roof this area? I am hesitant to use wood trusses due to carpenter bees and the fact that this site will sit unoccupied for weeks at a time. This is a location in the southeast US and far enough from the coast that hurricane winds aren't really a concern.

Thanks.
