Choosing between prefab modular buildings is usually a site-size question first and a lifestyle question second. A 20-foot-wide steel storage structure solves a completely different problem than a 7-foot-wide mobile office with a bathroom and bedroom. This head-to-head compares the DURO Steel Mini Self Storage 20x100x8.5 and the Chery Industrial 13x7FT Mobile Prefab Office with Bathroom & Bedroom to help you match the right building to your space and intended use.
Quick verdict
Need maximum covered square footage on an open lot? Pick the DURO. It gives you a 20x100-ft steel shell, engineered drawings, and anchor bolt plans. Need a self-contained workspace that functions as both an office and a place to sleep? Pick the Chery. It bundles a private bathroom with shower and a bedroom nook into one compact, prebuilt unit.

Where each product wins
DURO Steel Mini Storage 20x100x8.5 wins when your primary need is enclosed square footage. With 2,000 square feet of floor area (20 ft x 100 ft), it dwarfs the Chery unit. The package also includes an easy-to-read erection manual, full erection drawings, and an anchor bolt plan, which makes it a more documentation-heavy purchase for those installing a permanent steel building. It is engineered for 30 PSF ground snow load and 115 MPH wind load, with a 0.5:12 roof pitch.
Chery Industrial 13x7FT Mobile Prefab Office wins when you need a ready-to-use, compact structure that includes living amenities. It comes prebuilt and features a private bathroom with a soft-flushing toilet, a shower with mixer tap, vanity basin, anti-slip floor, and mirror with hidden cabinetry. The floor plan combines office space with a lounge sleeping area, so it works for remote work, guard posts, or temporary onsite accommodation.
Product notes
DURO Steel Mini Self Storage 20x100x8.5
This is the size play. The listed price is USD 16,778.00, and for that you get a 20x100-ft steel structure with 8.5-ft side walls and ten 9-ft wide x 7-ft tall roll-up door openings. The included engineering package details ground snow load, wind load, and anchor bolt plans, giving you the documentation needed for a permanent installation. The trade-off is that roll-up doors themselves are not included, so you will need to source those separately. Made in the United States, this building suits a large site where enclosed storage for multiple units, trailers, or heavy equipment is the goal.
Chery Industrial 13x7FT Mobile Prefab Office with Bathroom & Bedroom
Paired with the DURO, the Chery is all about compact convenience. At USD 12,500.00, it is the lower-priced of the two and brings a complete live-work setup: a bathroom with shower and flush toilet, a vanity basin, anti-slip flooring, and a bedroom/lounge area. It is prebuilt and includes a 1-year manufacturer warranty. The 13x7.2-ft footprint keeps it easy to place on tighter lots, but it also means you will not be storing large equipment inside. Choose it for a self-contained office, guard shack, or temporary living quarter where the bathroom and bed are worth more than extra floor space.
Final choice by use case
Go with the DURO Steel Mini Self Storage 20x100x8.5 if you have a wide-open site and need large-format covered storage or a workshop. Go with the Chery Industrial 13x7FT Mobile Prefab Office if your priority is a fully self-contained, compact structure with bathroom and sleeping space already worked in.
