Ideas That Started as a Steel Box
A few of the projects our neighbors around south Denver have pulled off.
Tiny Home
A 40ft High Cube finishes out into a one-bedroom place — many wrap up around $25K all in.
Guest House / ADU
Put up a backyard unit for visiting family or steady rent — allowed on most Arapahoe County lots.
Backyard Office
Drop a 20-footer behind the house for a quiet, sealed, climate-controlled office.
Workshop
A tough steel shell that takes a workbench, racks, and heavy tools without complaint.
Vacation Rental
A mountain-side container stay stands out in listings — guests book it for the look alone.
Pool House
Fit a 20-footer with a shower, a changing nook, and a small bar by the pool.

Not Sure Which Grade to Get?
Flip through the four below — for most conversions, Cargo Worthy hits the mark.
One-Trip (1-TRIP)
Barely used — one ocean voyage from the factory. Clean steel, full warranty.
Best for: Premium tiny homes and high-end ADUs where finish quality matters.
Cargo Worthy (CWO)
ISO/CSC-certified and inspected for ocean freight. Sound frame, fair price.
Best for: Most conversions — scuffs vanish behind insulation and cladding.
Wind & Water Tight (WWT)
Sealed against rain and snow, but no longer export-rated.
Best for: Storage, workshops, and budget conversion projects.
As-Is (AS-IS)
Sold as-is, no warranty. The cheapest way into a steel box.
Best for: Experienced DIY builders, fencing, or non-critical storage.
Built by Folks Down the Road
Honest words from south-metro owners who started with one of our boxes.
"Turned the 40ft HC into an amazing mountain Airbnb. Booked solid all summer — the container look is a big draw."
"My backyard office was ready in two weeks. Delivery onto a tight Parker lot was flawless — the driver knew exactly what he was doing."
"Got two 40ft CWs for an ADU project. Great price, no surprises, both arrived in spec."
"Bought a 20ft for my workshop. Solid steel, doors swung clean. Set up shop the same week it landed."
"As a first-time builder, the team walked me through what grade made sense for a guest house. Saved me from overspending."
"Picked up a 40ft HC One-Trip for our tiny home build. It looked brand new. Worth every dollar."

Questions We Hear a Lot
The short answers — dig deeper on our full FAQ page.
Most people land on the 40ft High Cube — that extra foot leaves you near 8ft of headroom once it's insulated. A 20ft High Cube is plenty for a studio or one-room guest space.
Yes — owners around here turn them into guest units, small homes, and offices all the time. Start with a Cargo Worthy or One-Trip box and you're on solid footing.
Cargo Worthy is the one to beat — the frame is sound, and any scuffs vanish behind insulation and cladding once you finish it out.
A tilt-bed truck eases it straight onto your spot. All we ask for is roughly 100ft of clear, straight room for the rig to back in.
For anything you'll live in, most counties want a permit. We can hand you off to builders who already know the Arapahoe and Douglas county desks.
Roughly $1,200 for a 20ft Wind & Water Tight up past $4,500 for a 40ft High Cube One-Trip. The in-stock list shows where each one sits today.
Figure a quarter-century or more in regular use. Corten steel shrugs off the snow, sun, and wind we get out here without rotting through.
